The Mark of Discord

The briefing room at FOB Calder smelt of burnt coffee and dust. That particular Afghan dust got into everything, no matter how often you cleaned.

Lieutenant Colonel Alistair Vane stood at the front beside a map that looked older than Hadley, pointing to coordinates that might as well have been on Mars for all the use our GPS had been lately.

"Sergeant Mercer, you'll be taking a resupply patrol up to OP Kestrel," he said, as if he were asking me to nip to the shop rather than drive roughly 48 kilometres through Taliban-controlled mountain passes. "Standard resupply. Medical stores, ammunition and rations. Should take eight hours there and back."

I nodded, already calculating the real time. Twelve hours if we were lucky, sixteen if we were not.

Lieutenant Imogen Clarke sat to my left, her Sandhurst posture making the rest of us look as though we were melting into our chairs. She had been taking notes since the briefing began, her pen moving in precise lines across the page.

Two weeks in theatre, and she still thought documentation mattered more than instinct. She outranked me and commanded the patrol, but she had formally delegated ground movement and tactical control to me. Sensible on paper. Less comfortable when we disagreed.

"Sir, I'm not seeing OP Kestrel on our digital mapping system," Clarke said, holding up her tablet. Of course she had noticed. "Those coordinates place it in unmarked terrain."

Vane barely glanced at her. "Technical problems with satellite coverage in that region, Lieutenant. Use the paper maps."

I watched Clarke's jaw tighten. She wanted to press him, but she was still new enough to swallow her questions.

The paper map on the wall showed OP Kestrel clearly, a small triangle marking an observation post overlooking three valleys. A strategic position, assuming anyone was actually there to observe anything.

Private Lewis Hadley sat on my other side, his knee bouncing like a pneumatic drill. The lad had been in theatre for six weeks and still jumped whenever a door slammed. His hands kept moving to his L85A3, then back to his lap, then to his water bottle. I had seen that nervous energy before in inexperienced soldiers. Sometimes it kept them alive. Sometimes it got them killed.

"Hadley, you're driving," I told him.

His knee stopped bouncing for precisely two seconds before starting again.

"Yes, Sergeant," he said, his voice cracking slightly on the second word. His Northumberland accent was still thick beneath the clipped phrases he had learnt at Catterick. "I've been practising mountain roads in the simulator."

The simulator. Christ. As if a programme could prepare him for roads crumbling beneath the tyres, or for the Taliban piling rocks where vehicles had to slow.

Corporal Nadiya Shah sat behind Hadley, her fingers moving across her communications equipment even during the briefing. She had been monitoring local traffic all morning, and her Pashto was good enough to catch nuances some translators missed. She looked up when she noticed me watching.

"Radio traffic has been quiet around those coordinates," she said. "Almost too quiet."

"Maybe they're all having a day off," Lance Corporal Bethan Price said from her corner without looking up from the medical supply list. "Even terrorists need holiday entitlement."

Price had the dry humour of someone who had watched too many eighteen-year-olds bleed because of stupid mistakes. Two deployments as a medic, though she had once said neither involved much real combat. Training accidents and heat casualties, mostly.

This would be different. I was not about to tell her that.

"You leave at 0600," Vane continued. "That should put you at OP Kestrel by midday and back before dark."

Clarke's pen stopped moving. "Sir, that assumes ideal conditions and no delays. The terrain analysis suggests-"

"The timetable is what it is, Lieutenant," Vane cut in. "Any other questions?"

She had about fifty. I could see them building behind her eyes like storm clouds, but she pressed her lips together and shook her head. At least she knew when further argument would achieve nothing.

After the briefing, we went to the vehicle park to prepare the Foxhound. The morning air was already heavy with heat, an oppressive weight that made every piece of kit feel twice as cumbersome.

Hadley walked around the vehicle three times, checking things he had already checked, his hands still shaking as he tested the tyre pressures.

"First combat patrol?" I asked, though I knew the answer.

"First time outside the wire, Sergeant," he admitted, trying to steady his hands by gripping the gauge harder. "Back in Northumberland, we didn't... I mean, the careers office made it sound different."

They always did. They sold lads trade training, qualifications and a steady wage, and left out the improvised explosive devices and watching your mates die.

I wanted to tell him it would be fine, that this was only a routine run, but the words stuck in my throat. My brother had believed my lies about everything being fine right up until he swallowed a bottle of tablets while I was training at Catterick.

Clarke appeared with a stack of paper maps and spread them across the Foxhound's bonnet.

"I've plotted three alternative routes," she announced. "The primary route has two known choke points where an ambush is statistically more likely."

"We're taking the main road," I said, without looking at her charts. "It's fastest."

"Speed isn't everything, Sergeant. A tactical analysis of-"

"Ma'am, how many resupply patrols have you done?"

Her silence was answer enough.

"You placed ground movement under my control," I said. "My recommendation is the main road. The longer we're exposed, the more opportunities they have to hit us."

She folded her maps with sharp, angry movements, but did not revoke the delegation or argue further.

Behind her, Shah was loading communications equipment into the vehicle, every item sealed in an anti-static pouch. She had rigged a field-expedient Bowman aerial booster with electrical tape and what appeared to be hope.

"Will that work?" I asked.

"It'll work until it doesn't," she said, which was about as optimistic as anyone became out there.

Price arrived last, dragging two medical bags that looked as though they weighed more than Hadley. She had raided the field medical facility for extra trauma supplies, dressings and morphine. Things we should not need on a simple resupply run, but would be grateful for if everything went wrong.

"Planning for casualties?" Clarke asked, the edge from our earlier exchange still in her voice.

"Always do," Price replied. "I'd rather carry the weight than watch someone bleed out because I didn't pack enough gauze."

We loaded the remaining supplies in silence. Boxes of operational ration packs nobody would want to eat. Ammunition for weapons we hoped would not be fired. Water bottles that would be hot enough to brew tea by midday.

Hadley kept checking his watch, counting down to 0600 as if it were the hour of his execution.

"Sergeant Mercer," Clarke said when we had finished loading. "I want it recorded that I consider this timetable unnecessarily aggressive."

"Noted, ma'am," I said, though we both knew nobody cared what went on the record. "Anything else?"

She hesitated, then took out her tablet again.

"The last contact from OP Kestrel was four days ago. A routine check-in. Nothing unusual, but four days is a long time to remain silent."

Four days was an eternity in a place where everything could go wrong in four seconds. Yet Vane had not seemed concerned. Either he knew something we did not or he did not care. Neither possibility made me feel better.

"Could be equipment failure," Shah offered. "The mountains play havoc with communications."

"Could be," I agreed, though my gut was already tightening. It was the familiar sense that something was wrong, the same instinct that had saved my section in Kandahar and failed my brother in Birmingham.

Hadley dropped a case of water, sending bottles scattering across the ground. His face reddened as he scrambled after them, apologising repeatedly. Clarke watched with poorly concealed frustration while Price crouched to help him.

"It's fine," I told him, though my patience was already thinning. "Just load them."

He nodded, his hands shaking worse than before.

I remembered being eighteen and thinking I was ready for war because I had played Call of Duty and listened to second-hand regimental stories. Reality was nothing like either. There were no respawns and no dramatic music, only heat, fear and the constant burden of knowing that any decision might kill everyone around you.

"Get some sleep," I told them. "0600 comes early."

They dispersed towards the accommodation block, leaving me alone with the Foxhound and my doubts. The vehicle sat like a metal coffin on wheels, waiting to carry us towards whatever waited at OP Kestrel.

I ran my hand along its armoured flank, feeling the dents and scratches from earlier patrols and wondering whether tomorrow would add more.

Clarke's paper map was still spread across the bonnet. I studied the route, memorising every bend and change in elevation. The outpost itself was marked by that simple triangle, but something about its position troubled me. It was too isolated and too far from support, as if someone had deliberately placed it where help could not reach.

My forearm suddenly itched. A sharp pain made me look down. At first I saw nothing but sun-darkened skin and old scars. Then, for an instant, I thought I could make out a faint grey thread beneath the skin near my wrist.

I rubbed it and the impression vanished, but the sensation lingered, like something crawling beneath the surface and trying to escape.

Tomorrow would be simple, I told myself. Drive up, deliver the supplies, drive back, keep everyone alive. Add another successful patrol to my record and pretend my luck would last for ever.

Hadley would get his first taste of the real Afghanistan. Clarke would learn that theories meant little once bullets began flying. I would do what I always did: whatever was necessary to bring them home.

The sun set behind the mountains, staining them the colour of dried blood. Somewhere among them, OP Kestrel waited in silence, roughly 48 kilometres and a world away from the relative safety of Calder.

I folded the map and headed for the accommodation block, the burden of responsibility settling on my shoulders like a physical weight.

Six hours until departure. Six hours to pretend I knew what I was doing, that my reputation meant something, that I could protect them all.

The fear sat in my stomach like a stone. It was not fear of dying. I had made peace with that possibility years ago. It was fear of failing them, of being exposed as the fraud I knew I was, of adding more names to the list of people I had not saved.

I lay on my bunk and stared at the ceiling, counting down the hours until morning. Outside came the ordinary noises of the base: helicopters landing, sergeants shouting, someone laughing at something idiotic.

Normal sounds in an abnormal place. The soundtrack of a war that had continued so long that nobody remembered what we were fighting for.

OP Kestrel waited in the mountains, silent and patient. The next morning, ready or not, we answered its call.

The smell reached us first.

It was the sickly, sweet mixture of burnt flesh and explosives that meant something had died violently. We had been climbing for two hours, the Foxhound's engine labouring against the gradient while Hadley gripped the steering wheel through hairpin bends with sheer drops beyond them.

"Stop," Shah said suddenly from the rear, binoculars pressed to the window. "Valley floor, ten o'clock."

I raised my binoculars and followed her gaze.

The narrow valley below our route was strewn with bodies. A shattered caravan of donkeys and goats lay scattered across the rocks like broken toys. Pieces of packs and household goods had been flung among them. Some of the carcasses were still smoking.

The crater pattern told the story plainly enough. Someone had authorised a drone strike on what they believed was an insurgent convoy. It had been a family moving animals and belongings through the valley.

"Christ," Hadley whispered, his face paling.

The lad had seen photographs of dead women and children during pre-deployment training, but this was different. This was waste on a scale that made no sense.

"Keep driving," I told him, but his foot was already coming off the accelerator.

"Are those...?"

He could not finish.

"Donkeys and goats," Price confirmed from behind him. "Probably belonged to a local family. Their entire livelihood."

Hadley pulled over so sharply that I nearly struck my head on the fascia. He was out of the vehicle and vomiting before anyone could stop him, his breakfast splashing across the rocks. The sound echoed from the canyon walls.

"We need to move," I said, scanning the ridgelines.

Nothing stirred above us, but stopping in the open invited trouble.

"We should have used the alternative route," Clarke said, her voice tight with contained anger. "I marked three routes that would have avoided this valley entirely."

"They would have added at least four hours," I said, still watching the high ground. "Four more hours of exposure."

"Against traumatising Private Hadley."

Hadley climbed back behind the wheel, wiping his mouth with the back of his hand. His eyes kept drifting towards the valley.

"I'm fine," he said, although his hands shook as he selected the gear. After we had travelled another hundred metres, he asked, "Why?"

I waited.

"Why kill animals? They're not Taliban. They're not anything."

I wanted to offer an answer that made sense, something about collateral damage and the fog of war. The truth was simpler and uglier. Someone had seen movement on a thermal feed and made a bad decision. It happened. We simply did not usually have to drive past the consequences.

"Sometimes people make mistakes," Price said when I did not answer. "Expensive, terrible mistakes."

"That's not a mistake," Hadley said, his voice cracking. "That's someone's whole life down there. Those animals were probably all they had."

He was right. In that part of Afghanistan, livestock could mean the difference between eating and starving. Some family would return to find its future reduced to carrion.

"Calder Operations, this is Kestrel Resupply One," Shah said into her radio, requesting confirmation of recent air activity at our grid reference.

Static swallowed her transmission. She changed frequency and tried again. More static.

"Mountains are interfering," she said, though her frown suggested she did not quite believe it. "I'm receiving fragments, then nothing."

Price took out her GPS unit and tried to mark our position for the return journey.

"That's odd," she muttered, showing me the screen.

According to the device, we were simultaneously five kilometres east and three kilometres west of our actual position.

"Try again."

She did. This time it placed us at FOB Calder.

"Useless thing," she said, pushing it back into her kit. "Good job we've got the paper map."

The paper map that showed OP Kestrel when nothing digital did. Our only guide through terrain that seemed intent on confusing every modern instrument we carried.

Hadley stopped again twenty minutes later, dry-heaving because there was nothing left in his stomach. The destroyed caravan had affected him worse than I expected. Perhaps because animals were innocent in a way people never seemed to be in a war zone. They chose no side, carried no weapons and planted no bombs. They merely tried to survive, and we turned them into smoke and meat.

"It's not right," he kept saying. "None of this is right."

Clarke watched him with an expression I could not read. Frustration, pity, understanding. She had been so focused on tactics and timetables that I wondered whether this was the first time she had truly considered what we were doing there.

"War isn't about what's right," I told Hadley. "It's about finishing the task and getting home."

"Then what is the task?" he asked. "What are we actually trying to achieve?"

Another question I could not answer. We were delivering supplies to an outpost that might not exist, through territory we barely controlled, in a war that had lasted so long that most people at home had forgotten British troops were still there.

"The task is OP Kestrel," I said, because that was easier than admitting I did not know either.

Shah tried the radio again as we climbed. She caught fragments: someone discussing weather, another voice requesting a casevac, then nothing but white noise painful enough to make her pull the headset away.

"I've never encountered interference this severe," she said. "It's as though the mountains are eating the signals."

The road narrowed until it was barely wide enough for the Foxhound. To our left, the mountain rose as a sheer wall of grey stone. To our right was a drop of perhaps a hundred metres.

Hadley's knuckles were white on the steering wheel. His breathing came in short, sharp gasps.

"You're doing fine," I told him, though I was gripping the door handle hard enough to leave marks.

"GPS is completely dead now," Price announced. "No false position. Nothing at all."

I studied the paper map across my lap. We were perhaps halfway to OP Kestrel, assuming its distances could be trusted. The route ahead promised more narrow roads, steep gradients and an isolation that deepened with every kilometre.

"There," Clarke said suddenly, pointing ahead. "Is that a checkpoint?"

A cluster of rocks had been arranged across part of the road, forcing vehicles to slow and weave between them. A familiar Taliban tactic: slow you down and make your movement predictable.

"Hadley, don't stop," I said. "Weave through."

"What if there's an IED?"

"Stopping won't help."

He guided the Foxhound between the rocks while all of us held our breath. Nothing detonated. Nobody fired. They might have been placed by insurgents or simply fallen from the cliffs. There was no way to know.

The sun was directly overhead, turning the vehicle into an oven. Despite the air conditioning, sweat streamed down Hadley's face and dripped onto his Multi-Terrain Pattern uniform. Price passed water forwards and reminded everyone to drink.

"How did they build an observation post up here?" Clarke asked, studying the map. "There's no infrastructure and no proper supply line."

"The same way they built everything else in this country," I said, then realised how inadequate that sounded.

She had a point. OP Kestrel's location made no tactical sense. It was too isolated to support other operations, too exposed to defend properly and too far from anything worth observing.

Unless something existed up there that we had not been told about. Something worth placing twelve soldiers on a mountain with no immediate support.

My forearm itched again. The same sharp sensation as the previous evening. I scratched at it absently while studying the map. The faint grey thread at my wrist had darkened, though I could still have mistaken it for grime or a vein.

We were entering country so remote that even local people seldom travelled through it, the kind of place where someone could disappear and never be found.

"I'm scared," Hadley said, so quietly I almost missed it.

"Good," I told him. "It means you're paying attention."

"Were you scared on your first patrol?"

I considered giving him the hard-sergeant performance, but he deserved better.

"Terrified. Threw up three times before we even went outside the wire."

"Did it become easier?"

"No. You become better at functioning while you're frightened."

Shah abandoned attempts to reach base and began monitoring local frequencies instead. Even those were silent. It felt as if we had driven beyond the edge of the world into a pocket where radio waves did not exist.

The road bent around a massive boulder. Beyond it, the landscape opened into a view that silenced us all. Mountains stretched in every direction, raw, hostile and utterly indifferent to our presence.

Somewhere among them waited OP Kestrel, in its impossible location, as silent as every frequency Shah tried.

"Another two hours," I said, consulting the map. "Perhaps three."

Nobody replied. We all knew the estimate was optimistic.

The road continued to deteriorate. Our equipment failed piece by piece, and Hadley looked ready to bolt from the vehicle if we stopped again. Still we climbed, because that was what soldiers did. We followed orders and completed tasks even after they stopped making sense, even when the mountains themselves seemed to want us gone.

The ruined caravan was kilometres behind us, but Hadley was still thinking about it. So was I. All that death for nothing, to be recorded as collateral damage in a report nobody would read.

Perhaps that was what we were: collateral damage that had not happened yet. Driving towards an outpost that should not exist through mountains that swallowed radio signals and confused satellites.

We continued anyway, guided only by the paper map, deeper into terrain that felt less like Afghanistan and more like the edge of something else.

The woman appeared beyond the next bend as though she had emerged from the rock itself. She stood in the centre of the road, clutching something wrapped in filthy cloth against her chest.

I had my hand on Hadley's shoulder before he could brake.

"Don't stop."

He was already slowing.

"There's a woman."

"I see her. Keep moving."

"She has a child," Clarke said behind me, reaching for the door handle. "We can't simply-"

"Yes, we can."

I kept my L85A3 pointing forwards while I watched the ridgelines. It was textbook: a lone distressed woman in the middle of nowhere. Insurgents had used variations of the same method since the Soviet occupation.

The woman began walking towards us, her voice carrying over the engine. The desperate pleading required no translation.

"She's asking for help," Shah said anyway, listening to the Pashto. "Her child is ill. She says he's dying."

Hadley stopped the Foxhound twenty metres from her. She continued towards us with the bundle in her arms, her face streaked with dirt, tears or both.

"We're combat troops, not a medical convoy," I said.

Clarke was already releasing her harness. "We have medical supplies. Price is a trained medic. What sort of people are we if we don't help-"

"Living people," I cut in. "This is exactly how they-"

"How they what? How desperate mothers try to save their children?"

Clarke's Sandhurst certainty made me want to shake her.

"Not everything is a threat, Sergeant."

The woman was perhaps ten metres away. I could see the bundle more clearly now. It was small and much too still. Something about the way she held it was wrong: too rigid, too careful.

"Stay inside," I said, opening my door.

"Sergeant-" Clarke began.

I met her eyes. "Ma'am, you put tactical control in my hands. Keep everyone in the vehicle."

Then I stepped out, rifle ready but not yet aimed at the woman. The sun struck like a physical blow, and sweat ran down my back almost at once.

The woman stopped when she saw me and spoke faster.

Shah translated through the open window. "She says, 'Please. My son is very ill. I walked from my village. I need medicine.'"

I moved closer, watching her hands, the ridgelines and everything except the thing I most needed to watch.

The bundle. Always watch the bundle.

At five metres, I saw the child's face. Grey, waxen, eyes half-open but seeing nothing. He had been dead for hours, perhaps days.

The woman continued pleading, but her eyes were not on me. They were looking past me towards the rocks.

My rifle was already rising when I saw the wires running from beneath the child's wrappings to something strapped beneath her clothes. She saw that I had noticed. Her hand moved towards the dead boy's body, where the trigger was probably concealed.

A shot came from high to our left.

The woman's head snapped back. She collapsed as if her strings had been cut, and the child's body rolled free. Blocks of explosive were taped to his tiny chest. A single wire connected them to the woman's vest, and the trigger mechanism remained clenched in her dead hand.

Then the world became noise.

Automatic fire struck from the high ground. I saw six distinct firing positions: two on the left ridge, two on the right and two ahead.

I threw myself down and rolled behind a rock far too small to protect me. Rounds sparked from the road where I had been standing.

"Contact left! Contact right! Contact front!"

I heard myself shouting as I returned fire at muzzle flashes I could scarcely see.

The Foxhound's engine roared. Hadley threw it into reverse, accelerated forwards and hauled it into a hard turn that nearly rolled us. He was driving like a lunatic, which was exactly right. A moving target was harder to hit.

"Where's Mercer?" Clarke shouted over the gunfire.

"Here!"

I scrambled towards the vehicle as Hadley swung it round again, the armour ringing beneath bullet impacts. Price kicked open the door and I dived through, landing hard on the floor.

"Shah, get us some bloody air support!"

She was already transmitting, unnervingly calm as she sent our position.

"Calder Operations, this is Kestrel Resupply One. Troops in contact at grid reference..."

An RPG screamed over us and detonated against the cliff, showering the vehicle with fragments of stone. Hadley wrenched the wheel left and we slammed into one another.

"I can't see them!" he shouted. "I can't see where they are!"

"Just drive!"

I pulled myself upright and fired towards the flashes. Clarke was doing the same from the other side, her Sandhurst training worth something after all. Price raised her rifle, but Clarke grunted and dragged her left arm back.

"I'm hit," she said, sounding almost surprised.

Price was on her immediately, cutting away the sleeve.

"Shrapnel, not a bullet. You'll live."

As she worked, she glared at me.

"This is your fault. You should never have got out."

She was right. I had broken my own rule, allowing the sight of a desperate woman to override my instincts. Except she had ceased to be a mother to the men on those ridges. She was only another weapon. The child had been dead before we arrived, his corpse turned into bait.

"Two minutes to air support," Shah announced, still impossibly composed.

Two minutes was for ever in a firefight.

Hadley kept us moving, wrenching the wheel in what looked like panic but resolved into a pattern designed to make us unpredictable. The simulator had taught him something after all. Some reflexes transferred.

I checked the ridges again. Six firing positions. Exactly six.

It was a standard insurgent ambush. They had expected us to stop and cluster around the woman, presenting an easy target. When that failed, they shifted to pinning us down and waiting for an RPG to find its mark.

A second rocket shrieked past, closer than the first. Hadley turned sharply. The Foxhound lifted onto two wheels before crashing back down.

"Where's that air support?" Clarke asked through clenched teeth while Price bandaged her arm.

Then I heard it: the beautiful sound of salvation, rotor blades approaching fast and low.

The Army Air Corps Apache swept over the ridge like an angry metal angel. The ambushers shifted their fire towards it.

A serious mistake.

The Apache's cannon opened up, tearing chunks from the ridge. The shooting ceased as abruptly as it had begun. One moment there was chaos; the next, only the circling helicopter and our heavy breathing.

"Clear," Shah reported after speaking to the aircrew. "They confirm six insurgents killed. No movement detected."

Six. I had counted correctly.

Hadley finally stopped the Foxhound. His hands shook so violently that he could not engage the handbrake. Tears streamed down his face while he stared through the windscreen.

"You did well," I told him. "That driving saved us."

He nodded but could not speak.

Clarke's arm was bandaged and the bleeding controlled. She stared at me with an expression I could not read. Not quite anger, but close.

"The child was already dead," I said, unsure why I needed to explain.

"I know," she replied quietly. "I saw."

"They used a corpse," Hadley said at last, his voice hollow. "They put explosives on a dead child."

Nobody had an answer. What could we say? That this was war? That people did monstrous things? That a dead child was merely another means of killing British soldiers?

The woman's body lay ahead of us. The child's corpse, still carrying its explosives, rested nearby. A Royal Engineers bomb-disposal team would have to clear both before anyone could use the road safely.

The Apache continued to circle, searching for further threats.

"We need to move," I said. "OP Kestrel is still two hours away."

"After this?" Price looked at me as if I had lost my mind. "We should return to base."

"Our task hasn't changed."

"Everything has changed. They were waiting for us. That was prepared."

She was right. The ambush had been laid for any patrol using that road, perhaps after insurgent observers saw us leave Calder or watched our ascent. We had no evidence of a leak, but someone had known a vehicle would come through.

"We continue to OP Kestrel," Clarke said, pale with pain. She looked at me. "Your tactical recommendation, Sergeant?"

"Press on, ma'am. Turning round means passing this position again before bomb disposal arrives."

She gave a tight nod. The decision was hers; the movement was mine.

"Hadley, can you drive?"

He wiped his face and nodded. His hands were steadier now, possessed of that strange calm that sometimes followed combat.

"The child," he said again, though it was not a question.

"I know," I told him. "I saw him too."

We drove around the bodies, giving them a wide berth in case of secondary devices.

The Apache escorted us for another ten minutes before being called away to another emergency. Shah thanked the crew over the radio, professional and composed as though the previous twelve minutes had not happened.

My forearm was burning. When I pulled back my sleeve, the faint thread had become a thin black line running from my wrist towards my elbow. It was not quite a vein, though it resembled one.

I covered it before anyone noticed.

The mountains rose around us, indifferent to what had happened. Somewhere above, OP Kestrel waited in its impossible location. We had lost time in the ambush, and the sun was already beyond its highest point. We would be returning in darkness, assuming we returned at all.

"Why?" Hadley asked suddenly. "Why use a dead child?"

"Because it works," Clarke answered before I could. "Because they know we'll stop for women and children. Because they depend upon our humanity."

"Then what's the point?" His voice rose towards hysteria. "If helping gets us killed, and refusing to help makes us monsters, what's the bloody point?"

I wanted to give him an answer about duty, protecting people or fighting terrorism. All I could picture was the dead boy turned into a weapon by those who should have protected him.

"The point is that we finish the task," I said at last. "We deliver the supplies, check OP Kestrel and get home."

It was not enough. I knew that, but it was all I had.

We continued into the mountains. The road narrowed and the drops grew steeper. Behind us, a Royal Engineers bomb-disposal team would be sent to clear the bodies and explosives. The official report would describe a failed ambush: six enemy killed, one friendly minor injury.

It would not mention the child.

The reports never mentioned the children.

The tyre tracks appeared about fifty metres beyond the point where OP Kestrel should have stood. Two faint lines climbed through the rocks at an angle that hurt my teeth to contemplate.

We had been circling the coordinates for ten minutes. Shah worked through every frequency while I checked the paper map again and again, as though the triangle might move to match reality.

"OP Kestrel, this is Kestrel Resupply One. Respond."

Her voice had become flat and professional. She had made the call perhaps twenty times.

"OP Kestrel, this is a supply patrol from FOB Calder requesting confirmation of your position."

Static. Always static.

"We're in the right place," I said, though the empty mountainside suggested otherwise.

There were only rocks and scrub where twelve soldiers should have been living and working.

"The GPS may be wrong, but these paper coordinates are exact."

"Then where is the post?" Clarke asked. For once, I had no clever answer.

Hadley leant forwards and squinted through the windscreen.

"Sergeant, those look like tyre tracks."

I followed his gaze. He was right. They were barely visible in the dust, leading up a slope that looked too steep for vehicles. The incline was not marked on our map. According to the contours, that whole section of mountain should not have existed.

"Could be an earlier patrol," Price said, though she sounded unconvinced.

"An earlier patrol to where?"

I raised my binoculars and followed the tracks until they disappeared around a formation two hundred metres above us.

"There's nothing up there according to the map," Clarke said.

"The map has already proved unreliable."

She wore the expression that meant a regulation or tactical doctrine was coming.

"We follow the tracks," I said.

"That exceeds our stated parameters," she replied. "We're meant to deliver supplies to OP Kestrel, not explore an unmarked mountain trail."

"OP Kestrel isn't where it's meant to be. Those tracks are our only lead."

"A lead to what? We should contact Calder and request clarification."

"With what radio?" I gestured towards Shah, who was still receiving nothing but white noise. "We're already here. My tactical recommendation is that we investigate."

Clarke considered the slope, then nodded once. "Agreed. Proceed carefully."

Hadley put the Foxhound into gear. The engine strained against the gradient, and the tyres scrabbled for purchase on loose stone. The incline was brutal, perhaps thirty degrees, steep enough to roll us if he made one mistake.

"Easy," I told him, though he was already doing everything correctly.

The lad learnt quickly.

The tracks carried us around the rock formation and another hundred metres upwards before levelling onto a narrow shelf cut into the mountainside.

There stood OP Kestrel, built into the mountain as if it had grown from the stone.

"How the hell...?" Price breathed.

The outpost was invisible from below, concealed by the mountain's natural curve and painted to match the surrounding rock. Even after seeing it, I had to concentrate to distinguish fortifications from stone. Whoever designed the position knew exactly what they were doing.

"That explains why ordinary satellite imagery wouldn't reveal it," Shah said. "It's concealed from above as well as below. It doesn't explain why it is absent from the task force systems."

The main gate stood open. It had not been damaged or forced. It simply gaped as though someone had forgotten to close it when leaving.

That was wrong. Nobody left a gate open in Afghanistan. Not ever.

"Where are the sentries?" Clarke asked.

A post of that size should have had at least two visible, with others in concealed positions. Nothing moved except dust in the wind.

Hadley eased us through the gate while we searched for threats.

The compound was larger than expected. Several buildings had been excavated into the mountainside. Reinforced positions overlooked the approach, and a helicopter landing pad had been carved from solid rock. It contained everything a remote post required to survive, except people.

"I don't like this," Hadley said. The brittle edge had returned to his voice.

Neither did I. My skin crawled with the sense of being watched, only worse. The air itself felt wrong: too thick, too still, too unnatural in some way I could not name.

We stopped in the centre of the compound, in a flat space about thirty metres across. Personal kit lay scattered about: bergens, water bottles, webbing. An L85A3 rested against a wall as though its owner had put it down for a moment. A half-eaten chicken tikka operational ration sat on a crate, the spoon still buried in it.

Beside it stood a mug of strong tea. I touched the metal and snatched my fingers back.

It was still warm.

A field kettle nearby had been boiled recently enough that a trace of steam clung beneath its lid.

For four days, OP Kestrel had failed to answer Calder. Yet someone appeared to have stopped eating and making tea only minutes before we arrived.

"Shah," I said, staring at the warm mug, "try the radio again."

Corporal Shah did, cycling through emergency frequencies and command channels, even trying to raise the Army Air Corps Apache that had saved us earlier. Nothing. Not even static now. Just dead air.

"It's not atmospheric," she said quietly. "Something's blocking us. It might be jamming, but it's more sophisticated than anything the Taliban has."

"Could be the mountain," Lance Corporal Price suggested. "All this rock around us, maybe."

But I'd served at mountain outposts before, and they always had some answer to the terrain: relay stations, signal boosters, something. This felt deliberate.

"Hadley, Price, stay with the Foxhound," I said. "Keep the engine running. If anything happens, you get out of here."

"What about waiting for you, Sarge?" Hadley asked.

"You don't wait. Something goes wrong, you drive back to Calder and report."

He nodded, but I could see him fighting the urge to argue. Good. It meant he was thinking rather than merely following orders.

Lieutenant Clarke was the patrol commander by rank, but before we'd gone outside the wire she had formally delegated ground movement and tactical control to me. She had the education and the commission; I had the years of judging when a quiet place was about to become lethal. So far, the arrangement had kept us alive.

"Ma'am, Shah, we'll check the main buildings," I said. "Quick sweep. We find anyone we can or work out what happened, then we leave."

Clarke was already moving, her L85A3 ready despite the bandage around her wounded arm. Shah took her equipment bag, probably hoping she might find a working radio inside.

The first building was the command post, its door standing open like the gate. Maps covered one wall, marking patrol routes and supply drops. Two workstations faced a bank of communications equipment.

A field kettle had recently boiled. Beside it sat a mug of strong tea that was still warm.

"Someone was just here," Clarke said, touching the side of the mug. "This is fresh."

The duty roster showed twelve names. According to the morning entry, all twelve had been present and accounted for. But accounted for to whom? Shah had been unable to raise OP Kestrel for four days.

The contradiction sat badly with me. Warm tea, powered equipment and a recently completed check against four days of silence. Either someone had falsified the record or time inside the post was not behaving as it should.

The second building was the supply depot, exactly where we were meant to deliver our cargo. There was plenty of room for what we'd brought. The shelves were already half stocked with ammunition and operational ration packs. Everything looked normal except for a box of rifle rounds spilled across the floor, as though someone had knocked it over while leaving in a hurry.

"Sergeant," Shah called from across the compound.

She had found the communications shack, a small reinforced building bristling with aerials. Inside, every piece of equipment was powered and apparently functioning. The displays showed good signal strength. Every frequency was clear.

But when Shah tried to transmit, nothing happened. The sets were not broken and the signal did not sound jammed. There was simply no response, as though each transmission were being swallowed before it could leave the building.

"This is impossible," she said, checking the connections, power supply and field-expedient Bowman aerial booster. "Everything is working perfectly, except it isn't actually working."

My forearm began burning again, the sharp pain spreading towards my elbow. When I glanced down, the black line had grown by perhaps two centimetres. It had begun to branch like a tiny bolt of lightning frozen beneath my skin.

I pulled my sleeve down before the others noticed.

"We need to check the accommodation block," Clarke said. "That's where they'll be if they're not on duty."

I knew she was right, but something in me did not want to open that door. The sense of wrongness was growing stronger, pressing against my skull like a headache that had not quite begun.

The door was closed but unlocked. I reached for the handle. The metal was cold, far too cold after an afternoon of fierce sun.

"Wait," I said, although I could not have explained why.

It was instinct again, the same instinct that had saved me before and failed me too. Clarke glanced at me, then eased the door open with the muzzle of her rifle.

The smell reached us immediately. Not death exactly, but something that made my mind refuse to understand what my eyes were seeing.

"Oh God," Shah whispered behind me.

Ten soldiers lay in their bunks. They looked almost peaceful, as though they had simply gone to sleep. Their boots had been placed neatly beside their beds and their weapons were secured in the racks.

Black veins spread across every exposed patch of skin. They formed intricate, identical patterns, like dark ink worked beneath the flesh by an impossibly precise hand. Looking directly at them made my eyes ache.

They were the same as the mark growing along my arm.

Clarke stepped towards the nearest body and I caught her wrist.

"Don't touch him."

"We need to check for signs of life."

"There aren't any."

I knew it with absolute certainty. Whatever had killed these soldiers, they had been dead for hours. Perhaps since that morning check that could not possibly have happened.

"What could do this?" Clarke's voice had gone clinical as she tried to force the impossible into a useful category. "A chemical weapon? A biological agent?"

I did not answer because I did not know. My arm was burning more fiercely now, the black line pulsing in time with my heartbeat.

Somewhere at the back of my mind, I could almost hear something. It was not quite a voice and not quite music, but it wanted my attention.

"We need to leave," I said. "Now."

For once, Clarke did not argue. We backed out slowly, as if noise might wake the dead. Once outside, she pulled nitrile examination gloves from Price's medical pouch and snapped them over her hands.

"Check your protective kit," she said, her training at Sandhurst taking over. "Respirators, gloves, full CBRN precautions. This may be biological."

But I knew it was not. I could not have said how. Whatever had killed those soldiers was not something our standard CBRN protective kit could filter out. The veins were too deliberate, too symmetrical, almost artistic.

"We need to document it," Shah said, taking out her camera.

She photographed the room with the same calm efficiency she brought to every task, although her hands trembled slightly.

"Task force intelligence will want evidence," she said. "Otherwise they won't believe us."

Clarke crouched near the threshold, careful not to touch anything.

"Look at the patterns," she said. "They're symmetrical. A biological agent doesn't produce identical symmetrical markings on ten different people."

She was right. The pattern matched from body to body: the same branching, the same density, the same faint suggestion of movement beneath the skin, even though the soldiers had been dead for hours and perhaps for days.

"Don't touch them," I said again.

"I wasn't planning to."

She stood, favouring her injured arm.

"They didn't die fighting, Sergeant. Their weapons are racked. Their boots are lined up. It looks as though they were compelled to prepare for bed, then lay down and never woke up."

I moved deeper into the accommodation block, trying not to look at their faces. Most were young, probably pleased when they'd first received a remote posting, thinking they might see some real action in the mountains. Instead, they had died quietly from something that left marks like infected tattoos.

On a makeshift desk - a board laid across two ammunition crates - I found several half-finished letters. One soldier was writing to his mum about the food. Another was telling his girlfriend about the sunrise, and how the view seemed to stretch for ever when the morning light struck the mountains.

"Sarge."

Hadley's voice crackled over the short-range radio from outside.

"How much longer? This place is... it's really getting inside my head."

"A few more minutes," I told him, although I wanted to leave just as badly.

We returned to the command post. Shah went straight to the radio bank while Clarke and I checked the workstations. Behind one desk, partly hidden from the entrance, a soldier was slumped over a map. Another had collapsed across the transmission console. Both bore the same black markings.

Ten in the bunks and two here. Twelve names on the roster. Every member of OP Kestrel accounted for.

"The equipment is still powered," Shah said. "They were transmitting when this happened."

She opened the logs and worked through them. The first entries were routine: supply requests, weather reports and all the dull traffic that filled military communications.

Then she reached an entry from three days earlier.

"Listen to this. '0800. Breakthrough in lower tunnels. Team Three reports significant archaeological discovery. Requesting guidance from command.'"

"Archaeological?" Clarke leaned over her shoulder. "What were they excavating?"

Shah scrolled down.

"Next entry, 0930. 'Proceeding with excavation despite lack of response from command. Find is too significant to delay. Greek inscriptions confirmed.'"

"Greek?" I said. "In Afghanistan?"

"Alexander the Great came through the region," Clarke said, her mind already racing. "His forces founded settlements and left artefacts, but that was more than two thousand years ago."

The later entries grew progressively more excited. They described structures and artefacts that should not have existed so far from any known historical site.

The final transmission was barely coherent.

"'2147. We opened it. God help us, we opened it. The dreams were true. She's been waiting so long.'"

That was all. Nothing came after it.

"She?" Clarke asked.

I did not answer. My arm had begun to burn again, worse than before. Beneath my sleeve, the black line had advanced and branched, just like the marks covering the dead.

"We need to leave," I said.

"We need to understand what happened," Clarke replied. "If something beneath this post killed them, we need enough information to protect ourselves and whoever comes after us."

"Our best protection is getting away from it."

"And then what do we report? Twelve soldiers dead with identical black veins, no explanation? Headquarters will send another patrol, then a recovery team, then another team if the first one fails. People will keep coming until someone works out what happened."

She was right, and I hated her for being right.

Every instinct I had was telling me to run, to get my patrol away before whatever had collected those twelve soldiers decided there was room for five more.

Shah had found a stack of excavation notebooks beside the command desk. They contained careful drawings, measurements and plans of tunnels extending from behind the post into the mountain.

"These aren't amateur notes," she said. "They were mapping the site properly."

The drawings were detailed and professional. The soldiers had been trained, given precise instructions about what to find and how to document it.

"This was their real mission," I said as the truth settled over me. "The observation post was cover. They were here to dig."

"For what?" Shah asked.

I thought about the log entry: Greek inscriptions, dreams and a discovery too important to delay. None of it made sense, but nothing about the mission had made sense from the beginning. OP Kestrel was absent from every digital map, hidden in the middle of nowhere. Its official silence had lasted four days, yet its kettle had only recently boiled. Twelve soldiers were dead from something that should not exist.

"Sarge." Hadley's voice came over the radio again, higher now. "There's something moving up here. I can't see it, but there's definitely..."

The transmission broke into static.

"Hadley," I said into my radio. "Hadley, report."

Nothing.

We ran for the door, abandoning the careful search in our need to reach him.

Outside, the Foxhound stood where we had left it, engine running. Price had her L85A3 raised as she scanned the rocks. Hadley sat behind the wheel, his hands fixed at ten and two, staring through the windscreen.

"Lewis?"

I approached carefully, rifle ready for whatever had frightened him.

He turned to me and his eyes were wrong. They were not injured or infected, only empty, as though he were looking through me at something a thousand metres away.

"I can hear her," he said in a flat, unfamiliar voice. "She's singing. Can't you hear her singing?"

"Hadley, snap out of it."

Price was beside him at once, checking his pupils and pulse.

"He's in shock," she said. "We need to get him away from here."

But now that Hadley had named it, I could hear it too. Not singing exactly, but a rhythm in the air, in the stone and in the beat of my own heart. My arm pulsed with every note. The black line was spreading as if keeping time with music only the marked could hear.

"Load up," I ordered. "We're leaving now."

We secured what we had unpacked and climbed aboard. Nobody mentioned the medical supplies and ammunition we would be leaving in a depot meant for soldiers who were already dead. Hadley moved into the passenger seat without being asked, his movements mechanical. Price took the wheel, her jaw clenched.

She repositioned the Foxhound towards the gate and stopped. The engine remained running.

Clarke looked back at the concealed entrance marked in the excavation plans.

"Sergeant, wait."

"We've waited long enough, ma'am."

"A brief investigation. No more than a look at the entrance and the first chamber. If we leave with nothing but photographs of bodies, headquarters will send people in blind."

"Those soldiers went in and died. Hadley can hear something that isn't there. My tactical advice is that we return to base immediately."

She met my eyes. She was pale with pain, her wounded arm held close to her body, but her voice remained steady.

"And my decision as patrol commander is that we establish what the immediate hazard is before we report. You've got tactical control underground. The moment you judge it untenable, we withdraw."

The pull inside my arm intensified at her words, urging me towards the mountain.

I could have pressed harder. Perhaps I could have persuaded her. Instead I told myself she was right about the next team and ignored the part of me that wanted to go down for reasons that had nothing to do with duty.

"Price, Hadley, remain with the vehicle," I said. "Keep it facing the gate. If we're not back in three hours, you return to Calder and report everything."

Price stared at me.

"You said we weren't waiting if something went wrong."

"This is different."

"Doesn't feel different."

"Three hours. No longer."

Hadley turned his empty gaze towards the mountain.

"She's still singing," he whispered.

I pretended not to hear him.

The tunnel entrance was exactly where the excavation plans said it would be: a narrow gap behind the supply depot that resembled a natural cave until we came close enough to see tool marks. Some were fresh, left by the dead soldiers. Beneath them were cuts far older than any modern excavation.

"This isn't Taliban work," Clarke said, running her gloved hand close to the wall without touching it. "Look at the surface. It's been polished."

The stone had been worked until it was almost as smooth as glass, catching our torch beams and throwing them back at strange angles. I had seen plenty of mountain tunnels in Afghanistan, rough passages hacked out for storage or ambush positions. This was something else.

"I'll tell Price we're entering," Shah said, adjusting her Bowman set.

The radio was dead. Not hissing with static as it had before, but utterly silent, as if the battery had been removed.

"Equipment failure?" Clarke asked.

Shah checked the battery, connections and power level.

"Everything is working. It simply won't transmit."

Brilliant. We were about to go underground with no means of contacting the two people guarding our exit. Every tactical manual ever written would have called it stupid.

Clarke moved deeper into the tunnel, her torch cutting through the darkness. She held her rifle awkwardly because of the bandaged arm.

"Ma'am, we should reconsider. Those soldiers found something down here that killed them."

"If we don't establish what it was, command will send another team. How many people die before someone investigates properly?"

She had made her decision and was waiting for me to accept it. Worse, my arm was pulling me forwards. The black line pulsed with each step into the mountain, as though it recognised the place.

The passage descended at a steady angle, not steep enough to require ropes but enough to burn in our calves. After several minutes the air changed. It became colder, but there was something else too, something that made my teeth ache.

It tasted of copper and old electricity.

"Anyone else finding it hard to breathe?" Shah asked, her voice tight.

We all were. We were not gasping, but each breath required effort, as if the air resented being drawn into our lungs.

After perhaps fifty metres, the tunnel opened into a chamber. Clarke stopped so abruptly that I nearly walked into her.

"Bloody hell," she breathed, and Clarke rarely swore.

The chamber was larger than the entire post above. Our torches barely reached its walls. What little they revealed made no sense.

Columns had been carved from the living rock and decorated with patterns that looked Greek but felt older. Stone reliefs depicted battles between figures that might have been gods or might have been something else. Every surface had been shaped with a precision that modern tools would have struggled to achieve.

"This cannot be here," Shah said, her voice very small. "Greek influence reached Afghanistan, but nothing in the accepted record accounts for this."

"Someone built it," I said.

Modern excavation equipment lay scattered around the centre of the chamber: picks, brushes, lamps and notebooks, the tools of a careful archaeological operation. The dead soldiers had been working down there for weeks, perhaps months, documenting everything.

I picked up a notebook and turned through measurements and detailed sketches. The handwriting was neat and professional.

"Listen to this," I said, reading an entry dated five days earlier. "'The inscriptions are certainly Greek, but the dialect is wrong. It appears older than anything in the historical record. Dr Julian Harcourt at the University of Oxford believes we may have found a pre-Alexandrian settlement, but that is impossible. The Greeks did not possess the technology to construct anything like this.'"

"Dr Harcourt," Clarke said, taking another notebook. "They were consulting academics."

"Looks that way. This operation was planned from the start."

I continued reading.

"'Lieutenant Colonel Alistair Vane knows we've found something significant, but continues to demand faster progress. He says we need results before the inspection team arrives next month.'"

Vane. Our Vane. The man who had sent us on a routine resupply run without mentioning that OP Kestrel concealed an archaeological operation beneath a mountain.

He had known about the excavation. Whether he had understood what the soldiers were uncovering was another matter.

"Sergeant," Shah called from across the chamber. "You need to see this."

Her torch illuminated something at the far end. My skin crawled before I saw it clearly. As we approached, the sensation worsened, like static building before a lightning strike.

It was a door nearly three metres high, carved from a single piece of stone unlike anything else in the chamber. Greek text covered its surface alongside symbols that looked older and more primitive. Fresh scratches and pry marks scarred its edges.

"They opened it," Clarke said, pointing to the gaps where the slab had been forced from its frame. "Whatever happened to them began behind this door."

The notebooks confirmed it. The final pages were excited and increasingly erratic. The team had spent days translating the inscriptions and prising at the seals. The last entry had been written in a shaking hand.

"'We did it. The door is opening. The dreams make sense now. She's been calling to us all along.'"

"She?" Shah asked. "The same 'she' mentioned in the transmission?"

I was staring at one line of Greek text that Shah had begun to translate. Even with my limited knowledge, I could identify a few words: warning, discord, punishment.

"It's a warning," Shah confirmed, tracing the letters without touching them. "Something about not disturbing the one who brings strife and discord. This section promises eternal punishment for trespassers."

"They ignored it," Clarke said. "They opened the door anyway."

"Or they couldn't help themselves," I said, thinking of the pull in my arm and the way my feet wanted to carry me towards the narrow black gap.

We stood there, three soldiers with enough sense to recognise danger, staring at a doorway that radiated wrongness. We should have left, sealed the tunnel and reported the site as contaminated. Training and logic both demanded it.

But the mark burned so fiercely that I could see its shape through my sleeve. Something beyond the door was waiting.

It had killed twelve soldiers but marked me instead.

"We need to know," Clarke said. "We can't report without understanding what happened."

She was right and wrong at once. We needed to know, but not for the reason she believed. I needed to know why I had been marked, why Hadley heard singing and why the entire mission felt as if it had been drawing me towards this place.

"Stay together," I said. "Nobody goes anywhere alone. We look, document and leave. Touch nothing."

Clarke nodded. Shah readied her camera, although I doubted any photograph would capture what lay beyond the door.

I approached slowly, fighting every instinct that told me to run. The gap was just wide enough for one person to squeeze through. The excavation team had been careful not to damage the slab more than necessary. Professional to the end.

My torch reached perhaps three metres into the darkness before the beam vanished. It was not blocked or reflected. It seemed to be swallowed, as though the dark itself were hungry for light.

"There's something in there," Shah whispered.

She was right. It was not moving or breathing, but it was present. It had been waiting a very long time for visitors.

I thought about the twelve dead soldiers and the black marks covering their bodies. I thought about Hadley outside, listening to a song no one else could hear. I thought about my own mark growing stronger with every step towards the ancient door.

"We go in together," I said.

The words felt like a lie. Whatever waited beyond that threshold was not waiting for all three of us.

It was waiting for me.

I squeezed through the gap.

"Sergeant, what the hell are you doing?" Clarke snapped.

I could not answer. My feet seemed to be moving without permission. Something inside my chest pulled me onwards like a hook beneath my ribs. The mark burned cold and advanced another centimetre as I crossed the threshold.

"Rowan."

Clarke caught my arm. It was the first time she had used my given name.

"This is what killed those soldiers. We need to leave now."

She was right. Of course she was right. But that no longer mattered when every cell in my body was screaming at me to continue, to see what had called me there.

"Give me a minute," I managed. The words felt thick in my mouth. "I need to see what they found."

"We've seen enough," Shah said behind us, her voice high with fear. "Dead soldiers, impossible ruins and warning inscriptions. What else do you need?"

Then my torch caught the space beyond the door, and we all fell silent.

It was a city.

An entire city had been carved from the living rock of the mountain. Streets extended in perfect grids between buildings that looked as though they had been lifted from ancient Athens. Columns, pediments and delicate architectural details stood where none of them could exist, deep beneath Afghanistan and preserved without decay for more than two thousand years.

"That's impossible," Clarke breathed, her grip loosening on my arm.

Thick dust lay undisturbed except for a path of military bootprints left by the soldiers from OP Kestrel. Their tracks followed a broad avenue between rows of empty stone houses. The black doorways watched us like eyes.

"How large is it?" Shah whispered, sweeping her torch across the impossible space.

The beam vanished without finding a far wall.

I began walking before deciding to move.

Clarke swore and followed. Shah came behind her, because leaving me alone in that place was apparently worse than coming with me.

Our footsteps echoed incorrectly. There were too many echoes, rebounding from surfaces we could not see.

The buildings were perfect. No roofs had collapsed. No walls had crumbled. No roots or weeds had broken through the streets. It was as if the city had been sealed in a bubble on the day it was built. Yet every window was empty, every doorway dark, and the silence was so complete that my ears rang.

"This would have taken decades," Clarke said, her analytical mind fighting to impose reason on what she saw. "Hundreds of workers, supply lines, an entire organisation. There should be records. Evidence."

"Unless they didn't want it found," I said, surprised that I could still form coherent thoughts while the pull strengthened with every step.

The avenue led straight towards the centre of the city, where a temple rose above everything around it. Massive columns supported a triangular pediment decorated with carved figures I did not want to examine closely.

The dead soldiers' bootprints led to its entrance.

"We should go back," Shah said. "We've documented enough. Let someone properly equipped handle the rest."

"There is no one else," I heard myself say. "We're here. We're already exposed to whatever killed them. We might as well know what we're facing."

It was logical rubbish, and all three of us knew it. Yet I was already climbing the temple steps.

They were worn smooth along the centre, as though thousands of feet had climbed them over centuries, although no one had done so recently until the soldiers arrived.

The temple doors were bronze, or made of something that resembled it. The metal had turned green with age but had not corroded. Scenes of war, storms and chaos covered the panels. Serpents ate their own tails among figures locked in endless conflict.

Inside lay a vast hall lit by nothing. A dim grey illumination filled it without any visible source, just bright enough to reveal the enormous statue at the far end.

She was beautiful and terrible.

A woman carved from black stone, nearly ten metres tall, sat upon a throne. Her face was serene, almost kind, while her hair formed a mass of serpents frozen in mid-writhe. Her hands rested on the arms of the throne, and even in stone they looked capable of reaching down and seizing us.

"Medusa?" Shah guessed.

But that was wrong. Medusa had been a monster. This was something else, something that had chosen to borrow a monster's shape.

The pull in my chest became almost painful, dragging me towards the statue. Clarke and Shah followed with reluctant, measured steps. Good soldiers following their sergeant into a nightmare.

When we were perhaps three metres from the plinth, a voice filled the temple. It was not loud and did not echo. It simply appeared inside our heads, as though it had always been there.

"Welcome," it said in perfect, unaccented English. "I have been waiting for one who seeks understanding."

Clarke raised her L85A3, although there was nothing obvious to shoot. Shah gripped my arm and tried to pull me back, but I stepped forwards, drawn by something stronger than fear or reason.

"The others came seeking treasure or knowledge," the voice continued, ancient and amused. "But you come seeking purpose. How refreshing."

The statue's eyes opened. They did not crack or shift. They opened like living eyes and fixed upon me.

They were gold, bright as newly struck sovereigns. Looking into them was like staring at the sun, if the sun could stare back.

"Sergeant, we need to run," Clarke said.

Her voice sounded far away, as though she were speaking through deep water.

"Run where?" the statue asked.

Its stone lips moved slightly, just enough to turn terror into horror.

"Back to your little war? Your meaningless missions? Your slow decay into purposeless violence?"

She was not wrong. That was the worst of it. Every word struck like a truth I had spent years avoiding.

"You felt it," she continued, her golden eyes never leaving mine. "The futility. The waste. Children sent to die for causes they do not understand, following orders from men who have forgotten why the war began."

I remembered being eighteen, believing Call of Duty and second-hand regimental stories had given me some idea of war. I remembered the careers office promising trade training, qualifications and a steady wage. None of it had prepared me for ruined villages, pointless patrols or the bodies of young soldiers sent to hold ground we would abandon days later.

"Who are you?" I asked. My throat felt lined with sand.

The statue smiled. Its stone lips curved in an expression that was almost motherly.

"I am discord. I am the necessary chaos that prevents stagnation. I am the conflict that drives growth. I am Eris, goddess of strife and discord, and I have slept for far too long."

Eris. Not Medusa or some nameless Greek monster. A goddess, if such things existed. With a talking statue before me, disbelief had become difficult to defend.

"The soldiers," Clarke said, recovering her voice. "You killed them."

"They killed themselves," Eris corrected gently. "Their minds were too small and too rigid. They could not accept what they had found. They broke like cups attempting to contain an ocean."

"And us?" I asked, already knowing the answer.

"You are different."

The golden eyes narrowed as they studied me.

"You have already broken, haven't you? You have seen how pointless your precious order is. You understand that sometimes chaos is the only honest response to an insane world."

My arm burned. The black mark spread visibly beneath the fabric of my sleeve.

Clarke saw it and took a step back, lifting her rifle towards me and the statue.

"Don't," I told her, although I did not know whether I was protecting Clarke or Eris.

"He is already mine," Eris said with quiet satisfaction. "The mark chose him when he first doubted his mission, when he wondered whether saving lives in a meaningless war was worth the cost."

"That isn't..."

I could not finish, because it was true. Every word was true.

"I offer understanding," Eris continued, her voice warm and inviting. "Purpose beyond following orders. Power beyond human limitation. All I ask in return is service."

"Service?" Clarke repeated flatly. "You want him to serve you."

"I want him to serve chaos. To plant discord where order has grown corrupt. To challenge systems that have forgotten their purpose. To become the necessary disruption that prevents humanity from stagnating into death."

It should have sounded mad. It should have sent us running. But inside an impossible temple, beneath an impossible city, with a goddess speaking through stone, madness had become relative.

"What happens if I refuse?" I asked.

The statue's expression did not change, but the air grew heavier.

"Then you die as the others died. Your mind breaks while trying to deny what you have seen. Your body fails as the mark consumes you. And your patrol..."

She left the threat unfinished.

"You're holding us hostage," Clarke said, anger cutting through her fear.

"I am offering a choice," Eris replied. "The same choice I offered the others. They chose poorly."

I looked at my patrol.

Clarke was brilliant and brave, trying to process something that belonged in no training manual. Shah was terrified but still holding her camera, still trying to do her job. They had followed me into the mountain because they trusted me. Above us, Price was waiting beside the Foxhound and Hadley had already been touched by Eris's song.

"If I agree," I said slowly, "my people go free and unharmed. No marks. No madness. No compulsion. You remove whatever hold the song has on Hadley. They leave this place with their minds and bodies intact."

"Of course," Eris said easily. "I require only one servant at a time, one agent of necessary chaos in your ordered little world. Their memories may blur at the edges, as mortal memories do, but they will carry no mark, madness or command from me."

"Sergeant, no," Clarke said, stepping forwards. "We don't make bargains with..."

"With what?" I cut in. "Gods? Monsters? Whatever she is, she's real, and she's offering a way out."

"She's offering you slavery."

"She's offering purpose," I said, and hated how deeply I meant it.

The statue's eyes flared like twin suns.

"Choose quickly," Eris said. "The mark is spreading. Soon the choice will be made for you."

I looked down. The black line had reached my elbow, dividing into patterns that hurt to follow. Soon I would resemble the bodies above.

"I need your word," I said, meeting those impossible eyes. "My patrol walks out unharmed. No marks, no madness, no compulsion. Hadley is released from the song."

"They may return to safe, ordered and predictable lives, if that is what you desire for them."

It was.

God help me, it was exactly what I wanted. Let their lives be ordinary. Let them be safe and bored and alive.

"Then yes," I said.

Something shifted in the world, as though reality had missed a step.

The statue smiled more broadly. For an instant, I could have sworn she was not stone at all.

Her golden eyes held mine as gravity holds planets, inescapable and inevitable. When she spoke again, her voice bypassed my ears and unfolded inside my mind as thoughts that were not mine but felt as though they should have been.

"You know my name," Eris said.

I did. Not because I had studied Greek mythology or paid attention in whichever school lesson had covered the ancient gods. I knew it in the way you sometimes know you are dreaming while still asleep: knowledge arriving from nowhere and everywhere at once.

"This city was mine."

The stone walls around us seemed to pulse with memory.

"It was built by those who understood that order without chaos is death. They worshipped properly, not with prayers and sacrifices, but through acts that kept the world turning and prevented humanity from hardening into predictable patterns."

Clarke still had her rifle trained on the statue, although we all knew how little use it would be.

"People lived here? Underground?"

"Not underground then," Eris replied, amused like a teacher correcting a slow pupil. "This city stood beneath the sun, a beacon of controlled discord, until jealous mortals decided my influence was too dangerous. They buried my domain, sealed my temple and attempted to chain chaos itself."

The mark on my arm pulsed, and I understood without being told. The burial had failed. An idea could not be imprisoned. A force of nature could not be chained.

Eris had merely waited.

"The soldiers released you," I said as the pieces aligned. "Their excavation broke whatever kept you contained."

"Released is the wrong word." Her lips curved with something like sympathy. "I was never imprisoned, merely inconvenienced. But yes, they opened the door. Poor creatures. Their minds were trained to see the world in simple divisions: enemy and ally, order and chaos. When they met something beyond those divisions, they shattered like ice dropped into boiling water."

"The black veins," Shah whispered. "That's what killed them."

"Divine madness," Eris said, as casually as though discussing the weather. "Their bodies could not endure my presence. Their minds could not accept that their entire understanding of existence was a comforting lie. I clouded their reason and drew them back to their duties. Two remained at their workstations. The others prepared themselves neatly for sleep. Then they died rather than face the truth."

I thought of the twelve soldiers above: two slumped in the command post, ten lying peacefully in their bunks, all marked by the same black pattern. They had come down following orders and doing their duty. They had died for it, just as we might have done.

"But you are different," Eris said, fixing me with those golden eyes. "You have already seen through the lie. You know your war has no purpose. Your missions accomplish nothing. Your orders come from men who have forgotten why they fight."

She was not wrong.

God help me, she was not wrong.

How many resupply patrols had I led to posts with no strategic value? How many soldiers had I watched die for ridgelines we abandoned a week later? The war had become its own purpose, a machine that existed only to keep itself running.

"So what do you want?" I asked, although some part of me already knew.

I want what I have always wanted. Balance. Order is necessary, but order without opposition becomes tyranny. Peace is beautiful, but peace without conflict becomes stagnation.

Humanity needs chaos to grow, to change, to escape the slow death of predictability.

"You want to start wars," Clarke said flatly.

Wars start themselves, Eris corrected. I merely ensure that they serve a purpose beyond destruction.

A forest fire clears old growth so that new life can emerge. A revolution topples a corrupt system. Even your meaningless war could serve a purpose, if properly directed.

The pull in my chest was growing stronger, like invisible hands dragging me towards the statue.

My feet moved without permission. One step, then another.

"Sergeant."

Clarke caught my arm with her uninjured hand, but I shook her off. Her wounded arm remained bound against her chest, the bandage dark where blood had seeped through during our descent.

"She's in my head," I told them, surprised by how calm I sounded. "She has been since we arrived. Maybe since before."

"Then we get you out," Clarke said. "Casevac, psychiatric treatment, whatever it takes."

"There is no out."

I was less than a metre from the statue now, close enough to see the scales carved into the serpents eating their own tails among the stone coils of her hair.

"Look at my arm."

I rolled up my sleeve. The black line had passed my elbow, branching into patterns that seemed to move whenever I looked away from them.

Clarke's face drained of colour.

"That is what killed the soldiers," she whispered.

"That is what will kill me," I corrected.

Unless you accept my offer, Eris finished, her voice warm and inviting. Serve as my agent in your world. Spread necessary discord where order has become corrupt. In exchange, the mark becomes a blessing rather than a curse. Power instead of poison.

"Power," I repeated, hating how tempting the word sounded.

The power to protect those you care about, she clarified, because apparently ancient goddesses could read minds. The power to see through lies. To understand true motives. To know which battles matter and which are meaningless. The power to become the leader you have always wanted to be, instead of the fraud you fear you are.

That struck harder than it should have. She knew my doubts, my fear of failing the patrol, the guilt I carried as routinely as my L85A3.

"And if I refuse?"

Then you die.

There was no cruelty in the answer. It was a simple statement of fact.

The mark will consume you within hours. Your patrol will probably survive. Their exposure has been limited. But you are already too far gone.

I looked back at Lieutenant Imogen Clarke and Corporal Nadiya Shah. They were good soldiers and good people. They deserved better than dying in an underground nightmare because their sergeant had led them into something beyond human understanding.

Lance Corporal Bethan Price and Private Lewis Hadley were still on the surface with the Foxhound, probably out of their minds with worry. Hadley was barely more than a lad. He did not deserve any of this.

"My patrol," I said. "If I agree, they leave here clean. No marks, no madness and no compulsion from you. They get to live normal, boring, safe lives."

If that is what you wish, Eris said, sounding amused. Though I suspect their lives will be anything but boring after what they have seen.

She had a point. How did anyone return to normal after seeing proof that gods were real and actively interfering with humanity?

"Then make them forget," I said. "Whatever you have to do, make them forget this place. Make them forget you. Leave them with nothing but a chemical leak that killed the soldiers."

Memory is troublesome, Eris warned. I can cloud it, redirect it and blunt its sharpest edges, but humans have an irritating tendency to remember truths at inconvenient moments.

"Then do your best."

"Sergeant, what are you doing?" Clarke demanded.

"My job, ma'am. Protecting my patrol."

I reached out and touched the statue's hand.

The world exploded into sensation. Colours that did not exist. Sounds without sources. Knowledge that no human mind was built to hold.

I saw the city as it had once been, full of people who danced along the edge of chaos and found joy in uncertainty. I saw its burial and the fear in the eyes of those who could not accept that discord was necessary. I saw centuries of waiting, patience and careful preparation.

Then I saw myself, not as I was but as I might become: a warrior who understood that destruction could be creation and chaos could sometimes be kindness. Someone capable of planting seeds of necessary discord and watching them grow into change.

The mark on my arm flared with cold fire. It spread several centimetres, racing towards my shoulder, then stopped. Instead of consuming me, it settled into my skin as though it had always belonged there.

It is done, Eris said. Her voice was gentler now, almost maternal. You are mine, and I am yours.

"When what is done?"

When the time comes, you will know what to do.

"What time?"

You will know. For now, take your patrol and leave. Tell whatever lies are necessary to protect them. Live as normally as you can, knowing that normality is an illusion. And when I call, answer.

The golden eyes closed. One moment they had gleamed like newly struck sovereigns; the next, she was only a statue again, carved stone in an impossible temple beneath an impossible city.

The mark remained, dark and real, pulsing in time with my heart.

"We need to go," I said, turning back to Clarke and Shah.

They stared at me as though I had grown another head.

"What just happened?" Clarke demanded. "What did you do?"

"I made a choice. Now we leave. We report a suspected chemical leak, and none of us ever speaks about this place again."

"You cannot be serious. I am the patrol commander."

She was right. By rank, the patrol was hers. Before we had gone outside the wire, however, she had formally delegated tactical movement and ground control to me because I had more experience. That did not give me the right to order her about now, and we both knew it.

So I did not pretend otherwise. I stepped close and held her gaze.

"Then make the command decision, ma'am. Look at Shah. Think about Price and Hadley waiting above us. Think about the twelve soldiers in this mountain. If we stay, we become them. We leave now."

Clarke studied me, breathing hard. Her injured arm trembled in its sling.

At last, she gave a tight nod.

"Move," she said.

We climbed back through the tunnels. Shah stayed close behind Clarke, helping her across the broken ground whenever the pain in her arm upset her balance. I took the lead, my L85A3 raised, although I knew no rifle would protect us if Eris changed her mind.

Her presence faded as we climbed, but it never disappeared. She remained at the back of my mind, patient and eternal, waiting for the moment when she would collect her debt.

I had saved my patrol, or at least given them a chance. In return, I had agreed to serve discord in a world already tearing itself apart.

As we moved towards the daylight, I wondered whether I had prevented a disaster or caused one.

Probably both. That seemed like Eris's style.

The mark pulsed once in agreement.

My life as an ordinary soldier was over. Whatever came next, whatever she asked of me, I would face it. That was the price of making a bargain with a goddess. You lived with the consequences, even when living meant becoming something you had never wanted to be.

The tunnel entrance spat us into the daylight as though the mountain had swallowed us and found us disagreeable.

I stumbled onto the rock shelf, blinking against a sun that felt wrong after the grey, sourceless light of Eris's temple.

Hadley's voice cracked with relief.

"Sarge, Jesus Christ. Where were you?"

He stood beside the Foxhound with his L85A3 clutched in shaking hands, looking ready either to fire at the mountain or be sick against it.

"You were gone for nearly three hours. Price was about to come looking for you."

Nearly three hours.

It had felt like forty minutes. Perhaps less. Time became unreliable when you were bargaining with ancient gods.

"Chemical weapons," I said.

The lie came as smoothly as water.

"A compromised Soviet-era nerve-agent cache. The soldiers must have breached the storage chamber when they broke through the tunnel wall."

Clarke moved towards me, her analytical mind already changing direction.

"Nerve agent? Are we contaminated? We need CBRN procedures and an immediate medical assessment."

"The main contamination is confined to the lower chambers," I said, pulling down my sleeve to hide the mark. "The outer seals mostly held, but the soldiers who opened the inner door took the full dose. It explains the deaths and why they all lay down as though compelled before they died."

It was a good lie because it gave every impossible detail a shape that people could recognise. The Soviet occupation had left all manner of lethal rubbish across Afghanistan. A forgotten nerve-agent cache inside a mountain would barely register among the stranger things task force headquarters had heard that year.

"We need to report this immediately," Clarke said.

Something in her eyes had changed. She watched me as though seeing me for the first time, aware that something was wrong but unable to name it. Eris's promise was already taking hold. Clarke remembered the danger but seemed unable to hold the temple clearly in her mind.

"Calder Operations needs to know," she added.

"Agreed," I said. "But first we seal the accessible entrance. The post has demolition stores for emergency denial. There should be charges in that shed."

"You do not get to make that decision alone," Clarke said. There was less force behind the challenge than there should have been, as though she were trying to remember why she distrusted me.

"No, ma'am. But I am asking you to authorise it. We have twelve dead soldiers and a suspected nerve-agent cache that could threaten every person at FOB Calder if anyone blunders into it. We seal the route, report the contamination and let a British CBRN response and a Royal Engineers recovery team handle the rest."

I met her eyes steadily. The confidence in my voice surprised me. I had spent years second-guessing every decision, terrified that the next mistake would kill someone under my care.

Now I simply knew.

Clarke looked towards the tunnel, then at Shah and Hadley.

"Do it," she said. "Only the entrance. We leave the rest of the site intact for recovery."

"Understood, ma'am."

Hadley was staring at my sleeve.

"Sarge, your arm. You're bleeding through it."

I looked down. Dark lines showed through the fabric like spilt ink. It was not blood, but he did not need to know that.

"Caught it on some reinforcing bar in the tunnel," I said. "Price, can you have a look?"

Hadley was already shouting for her.

"Doc, the sergeant's hurt. His arm looks bad."

Price emerged from the far side of the Foxhound, where she had been checking the medical and CBRN protective kit. She had her trauma pouch in hand before she reached me, professional instinct overriding every question.

"Sit down. Let me see."

I sat on the rear step of the vehicle while she rolled up my sleeve.

The mark was beautiful in its own twisted way. Black branches spread beneath my skin in patterns that shifted whenever they were not observed directly.

Price frowned and examined it with nitrile-covered fingers.

"This isn't a laceration," she said slowly. "It looks more like severe bruising. Maybe a chemical burn. I don't know."

"Probably minor exposure to whatever killed the soldiers," I said. "I noticed it while we were examining the lower chamber."

She cleaned it with alcohol, which did nothing, applied antibiotic cream, which was equally pointless, and covered it with a thick gauze dressing. At least that hid it.

Her hands remained steady, but I caught her glancing at my face with the same expression Clarke had worn. She sensed that something fundamental had changed, even if Eris would not let her understand what.

While Price finished the dressing, I sent Hadley and Shah to retrieve the demolition stores. Clarke supervised, pale with pain and fatigue, her wounded arm held close to her body. We placed the charges carefully around the tunnel mouth, enough to bring down tonnes of rock without collapsing the command post or accommodation block above.

It would seal only the entrance we had used. I knew it could not imprison Eris. Nothing we carried could do that. At best, it would delay the recovery team and discourage anyone from digging without proper precautions.

The dead soldiers would have to be recovered eventually, but not by us. Not that day.

"Shah, get Calder Operations on Bowman," I said. "Report that the resupply has been completed but we have found suspected chemical contamination. Recommend immediate quarantine and specialist recovery."

She nodded and adjusted the field-expedient aerial booster. The set crackled, then cleared. We were far enough from Eris's influence for the electronics to work again.

"Calder Operations, this is Kestrel Patrol. Mission complete with complications. Break."

Shah delivered the report with clinical precision. Twelve personnel found dead. Suspected compromised Soviet-era nerve-agent cache. OP Kestrel to be treated as contaminated. Immediate CBRN response and Royal Engineers support required.

Calder Operations accepted the report without question.

Of course there were chemical hazards hidden in the mountains. Of course the soldiers had died from exposure. It made far more sense than the truth.

While Shah handled the radio traffic, I returned to the accommodation block one last time.

Most of the dead lay in their bunks exactly as we had found them. Two remained slumped in the command post. Twelve soldiers in total, each bearing the same black veins across the skin, as though death had tattooed them before they lay down.

The still-warm mug of strong tea and recently boiled field kettle remained where someone had abandoned them. Equipment still hummed despite the post's four days of silence. The contradiction was impossible, and now deliberate: four days since routine contact, yet everything suggested the soldiers had been alive minutes before we arrived.

I gathered their notebooks, excavation logs, survey sketches and every scrap of evidence describing what they had truly uncovered.

"What are you doing?"

Clarke had followed me. Of course she had.

"Protecting them," I said, feeding the papers into a document-destruction sack. "Their families do not need to hear that they died because someone ordered them to dig too deeply and open something that should have remained sealed. Let them be told it was a compromised nerve-agent cache. Clean, comprehensible and no less heroic."

"That is not your decision to make."

"No. It is yours, ma'am. But Lieutenant Colonel Vane knew this excavation existed, even if we cannot prove he understood the danger. He pushed them for results. If we send these records back, task force headquarters will send more people into that tunnel. More soldiers will die."

I faced her. Something in my expression made her take half a step back.

"The twelve are dead," I continued. "Nothing we do can change that. But we can decide whether anyone follows them."

Clarke watched me carry the sack outside and empty the papers into the burn bin. She could have stopped me. She outranked me and remained the patrol commander.

She did not.

The excavation records curled into ash. Careful notes, measurements and drawings blackened and vanished in the smoke. When the fire had finished, only the ordinary duty logs remained: sanitised, routine and dull.

"You're different," Clarke said quietly. "Something happened down there. Something you aren't telling us."

"Chemical exposure can alter behaviour," I said. "It may be adrenaline and stress. I'll be assessed when we return to base."

Another lie, smooth as the first. I was becoming good at them.

We loaded the Foxhound and prepared to leave OP Kestrel as the sun descended towards the mountain ridge. Hadley returned to the driver's seat, steadier now that we were going home, though he kept glancing at me in the rear-view mirror. Price sat beside him, monitoring him for signs of distress.

Clarke and Shah rode in the rear with me, silent and thoughtful. Clarke's memories of the temple were already losing their edges. Shah looked troubled whenever she glanced towards the sealed tunnel, then seemed to forget what had caught her attention.

Once the vehicle had cleared the immediate blast area, Clarke gave the order.

I triggered the charges.

The explosion rolled through the mountains. Dust boiled across OP Kestrel, swallowing the concealed entrance. When it cleared, the tunnel mouth had disappeared beneath tonnes of broken rock.

It would not keep Eris contained. She had waited for centuries. She could wait a little longer.

"Calder Operations confirms quarantine measures are active," Shah reported. "A British CBRN team and Royal Engineers recovery element will arrive within seventy-two hours."

They would find the sealed entrance, the twelve dead soldiers and traces pointing towards a chemical threat that did not exist. They would wear respirators and protective suits, take samples, write reports and notify families. The official account would settle around the truth like concrete.

The war would continue its pointless grind, and nobody would know that beneath the mountain a goddess of strife and discord waited in an impossible city.

Nobody except us.

If Eris kept her promise, even that knowledge would fade for the others. It would become a half-remembered nightmare, something glimpsed in sleep and lost on waking. Hadley's distant memory of the song would lose its compulsion. Clarke, Shah and Price would carry unease, but no marks and no madness.

The mark on my arm pulsed beneath the gauze and my lies.

I could feel Eris in the back of my mind. She did not speak. Her presence was like music playing in another room, too faint to distinguish the words.

She would call when she was ready. Until then, I had to pretend to be the same Sergeant Rowan Mercer who had left FOB Calder that morning.

"You all right, Sarge?" Hadley asked, meeting my eyes in the mirror.

"Yes," I said, and meant it.

For the first time in years, perhaps for the first time ever, I felt all right. Not good and not happy, but settled. I finally understood that I had a purpose, even if that purpose meant serving discord itself.

"Just ready to get back," I added, which was true enough.

Back to FOB Calder, where I would file false reports and pretend everything was normal. Back to a war that made no sense, serving commanders who had forgotten why we were fighting. Back to a life that was about to become far more complicated.

The sun set behind us as we descended through the mountain passes, staining the sky red and purple. The colours looked like warnings or promises. I could no longer tell the difference.

Price checked my dressing once more, frowning at the way the gauze had darkened where it touched the mark.

"You need that examined properly when we get back," she said. "That isn't normal bruising."

"Nothing about today was normal," I replied.

It was probably the most honest thing I had said since emerging from the tunnel.

She nodded slowly, accepting that much.

We drove into the darkness that swallowed the mountains. We passed the site of the ambush, where dust had already covered the blood from the six insurgents killed by the Army Air Corps Apache. Farther on, we passed the remains of the donkey-and-goat caravan destroyed by the mistaken drone strike that morning. By nightfall, the scavengers would come.

The war continued around us, indifferent to what we had found, lost and become.

In the back of my mind, patient as stone and inevitable as gravity, Eris waited.

I waited with her, knowing that my life as a simple soldier following simple orders had ended for ever. Whatever came next, whatever she asked of me, I would be ready. That was what happened when chaos marked you.

You adapted. You survived. You served your new purpose, even when that purpose was to spread discord through a world already falling apart.

The mark pulsed once beneath its bandage, like approval.

I closed my eyes for the rest of the journey back to FOB Calder.
