The Purple Harvest

The briefing room at NATO Forward Operating Base Otopeni, north of Bucharest, smelt of burnt coffee and testosterone. It was the usual Monday morning mixture, and it made me nostalgic for almost anywhere else.

Colonel Harriet Ashcombe stood at the front, her uniform pressed sharply enough to cut glass, clicking through satellite images on the wall display.

"Fourteen Romanian nationals missing from villages across the Fagaras Mountains," she said. Her British accent cut through the recycled air. "Local authorities are promoting the Russian infiltration theory, but NATO wants independent verification."

Political theatre. The Russians had not operated that far west in years, but they remained a convenient bogeyman.

I kept my face neutral. Across the table, Nadia Price caught my eye and raised one sceptical eyebrow. She was not buying it either.

"Your objective is reconnaissance only," Colonel Ashcombe continued. Her green eyes travelled across our four-woman patrol. "Document, assess and report. No engagement unless you are directly fired upon."

The display changed to an aerial view of Carta, a hamlet tucked into the Fagaras foothills like a secret someone had forgotten to keep.

"One road in and the same road out. Population 287 at the most recent census. Carta has been under a complete communications blackout for nineteen days. No mobile signal, no internet and no landlines."

Her hand trembled as she clicked to the next slide. It was barely perceptible, but after two years of reading people in combat zones, I noticed. Whatever had frightened her, it was not Russians.

Dru Bennett leant forwards and adjusted her glasses. "Ma'am, what about the Romanian military? They must have sent someone."

"A mountain-gendarmerie patrol. It failed to report back."

The room went quiet. Even Nadia stopped fidgeting with her pen.

"The weather has been clear," Colonel Ashcombe added, as if weather might explain trained personnel vanishing. "You deploy at 0600 tomorrow. Questions?"

Nobody had questions. We had concerns, doubts and that special dread attached to missions where the briefing created more mysteries than it resolved, but no questions.

Outside, we gathered at the equipment lockers like schoolchildren comparing dinner money. Nadia took out her rifle and checked the sight.

"So we're really doing this? Marching into Dracula country to find some missing villagers?"

"It isn't Dracula country," Dru muttered as she loaded technical equipment into her pack. "You're thinking of Wallachia."

"Same difference. Transylvania, vampires, mysterious disappearances." Nadia grinned, but the smile never reached her eyes. "Perhaps I should pack garlic."

Marta Kowalska checked her rifle in silence, her movements mechanically precise. When she thought nobody was looking, she crossed herself. The quick, practised gesture made me wonder what she knew that we did not.

"It's another reconnaissance patrol," I said, trying to inject confidence I did not feel. "We go in, document what we find and come out again. Simple."

Nobody answered. We all knew simple missions did not require a specialist reconnaissance troop operating within UK Special Forces support structures.

The helicopter lifted from Otopeni at precisely 0600 on Tuesday, 3 November 2026. It carried us across a Romanian landscape that grew emptier by the minute. Bucharest gave way to towns, the towns to villages, and the villages to nothing but forest and mountain.

The pilot, Warrant Officer Lucian Ionescu, was a weathered Romanian who looked as though he had been flying since helicopters were invented. About forty minutes into the flight, he began glancing repeatedly at his instruments.

"Compass and avionics interference," he announced. "It is worsening as we approach."

"Is that normal?" I asked.

He laughed, and it was not a comfortable sound. "Nothing about this region is normal. I will have to put you down early."

We landed in a frost-covered clearing three kilometres from Carta. The rotors slowed, and silence rushed in to occupy the space they left behind. It was the kind of complete quiet that reminded you how much noise the living world usually made. There were no birds, no insects and not even wind among the trees.

Dru took out her motion sensor as we formed up. Its display remained blank.

"Equipment failure?" Nadia asked.

"No. It's working." Dru tapped the screen. "There are simply no movement signatures. None at all."

The forest path to Carta was barely wide enough for us to proceed in single file. Our boots crushed frozen leaves, the sound obscenely loud in the stillness. Every few metres I caught myself looking over my shoulder, certain that something was watching us. Dru's sensor remained empty, however, and the forest remained dead.

We smelt the village before we saw it. Woodsmoke and livestock should have meant civilisation, but the smoke was old and stale, and there were no animals to be heard.

The trees thinned around the main road. Three vehicles blocked the entrance to Carta, abandoned at awkward angles as though their drivers had stopped in a hurry. Doors stood open. A child's stuffed rabbit lay in the mud beside one of them.

I approached the nearest car, a battered Dacia Logan with Romanian registration plates. The keys remained in the ignition. Its engine was so cold that touching the bonnet hurt my palm.

"It's been here a while," Dru said after checking another vehicle. "Dead battery. Half a tank of fuel."

Nadia looked through the rear window of a small van. "Shopping in the back. Milk, bread, vegetables. All spoilt."

The villagers had been leaving, or attempting to leave, when something made them abandon their vehicles at the very edge of the hamlet.

"Tactical formation," I ordered, pleased that my voice sounded steadier than I felt. "Weapons ready. Proceed as trained."

We moved into Carta. Its main street was lined with modest houses that should have displayed all the ordinary signs of life: washing on lines, smoke rising from chimneys, faces behind curtains. Instead there were closed doors, dark windows and an oppressive silence that made my teeth ache.

The Orthodox church stood in the centre of the village, its door hanging open like a mouth arrested in mid-scream. Beyond it were more houses, a Romanian primary school and a small magazin mixt, the village shop. All were empty. All were wrong.

"Where is everyone?" Marta whispered. They were the first words she had spoken since we left the base.

I had no answer. Looking at my patrol, at Nadia's failing bravado, Dru's white-knuckled grip on her equipment and Marta clutching her rifle like a lifeline, I knew we all felt the same thing.

Whatever had happened in Carta was not over. It was waiting.

The first house stood three metres from the church. Its blue door was open just far enough to make the back of my neck prickle. I raised a fist to halt the patrol, then pointed to Dru and the entrance.

She nodded. Dru entered low while I covered high. The hallway smelt of spoilt milk and the sweetly sick odour of food left too long. Three coats hung beside the door, with shoes arranged neatly underneath. Everything was ordinary except for the dust already settling over it.

"Clear," Dru called from the kitchen.

I found her staring at the table. Three places had been laid for breakfast. Black mould had claimed the bread, and the eggs had turned green and collapsed. Half-full coffee cups held a skin of scum. A fork rested on one plate with a piece of food still impaled on its tines.

"They just left," Dru said.

She touched the television in the corner. Static hissed across the old cathode-ray screen. Despite nineteen days of abandonment, the casing was warm.

"Why leave the television on?"

A calendar hung beside the refrigerator. An entry had been written in red: "15 November 2026 - clinic, 10.00." It was the remnant of an ordinary life, interrupted before the appointment could arrive.

We cleared six more houses during the next hour. Each told the same story. Meals had been abandoned, televisions continued to murmur and lives had stopped in the middle of mundane acts. In one house, a bath had overflowed long ago, sending damp and water damage through the ceiling below. In another, a sewing machine remained threaded, with cloth pinned beneath its foot and a hem waiting to be finished.

The primary school crouched at the end of the street, its windows dark. Inside, small chairs surrounded low tables and colouring books lay open at unfinished pages. The smell was worse there. Cartons of sour school milk in the dining room mingled with the waxy odour of crayons and paper.

Children's pictures covered the walls, their edges curling and their colours fading. Most showed the usual things: houses with smoking chimneys, families holding hands and dogs with too many legs. In a back corner, separated from the rest, I found a different collection.

The pictures showed stick figures with raised arms, staring at red circles in black skies. One pupil had drawn eyes inside the circles.

My radio crackled.

"Boss, you need to see this." Nadia's voice was steady but taut.

The magazin mixt stood opposite the school. Nadia waited behind its counter beside an open till. Romanian lei remained stacked in the compartments, and coins were scattered where someone had been giving change.

"Nobody robbed it." She lifted a shrivelled brown apple from a display. "The fruit is rotting and the dairy stock is well past its date, but all the money is here. I found a wallet on the floor as well, cards and everything."

"Anything else?"

"Yes."

She led me into the rear office. A delivery schedule on the wall recorded shipments until nineteen days earlier, then stopped. Beside it, someone had taped up a page of handwritten observations.

"Ion Barbu saw the lights again. Third night. Sorina Dobre's chickens will not lay. Dogs howling at nothing."

They were the kind of notes people in an isolated community made when they knew something was wrong but lacked the words to describe it.

"We'll establish our command post in the pensiune," I said. "Central position and several exits."

The concrete-built pensiune occupied the heart of Carta. It had a bar and a dining room large enough for thirty people, though only dust motes occupied it now. Empty glasses stood on the tables, and a chess match remained frozen halfway through.

Marta unpacked the radio equipment on the bar, her hands moving with practised efficiency. Static filled every frequency. It was not normal interference. There was a rhythm beneath it, slow and regular, almost like breathing.

"The atmospherics are all wrong," she said quietly. "This isn't natural."

While she worked, I examined the reception desk. The guest register lay open beside two fountain pens. Its final entry was dated nineteen days earlier and written in a shaking hand.

"Strange lights again last night. The animals know something."

I turned back through the pages. Two months earlier, everything had been normal: visitors from Bucharest, a German walking party, locals reserving the dining room for a birthday. Then the references began. "Beautiful aurora last night" became "Lights kept me awake", then "Why won't they stop?"

"Imogen." Dru stood in the doorway of the back office. "I've found something."

The innkeeper's room was organised chaos: invoices, family photographs and half a sandwich fossilised on a plate. An old wooden desk dominated the space. Its drawers were locked, so I forced the lowest one with my knife, splitting the wood around the catch.

A leather journal lay inside, worn smooth by handling. The handwriting matched the register, though the earliest entries were steadier and more deliberate.

The first relevant entry was dated two months before our arrival.

"Aurora borealis appeared last night, although the weather service said it was impossible at this latitude. Beautiful, but wrong somehow. The dogs would not stop barking."

As I read onwards, the writing deteriorated.

"The lights came on three consecutive nights. Ion Barbu says he lost four hours. He went to inspect his sheep at 0000. The next thing he knew, dawn had come and he was standing in his kitchen. His wife found him there, still wearing his boots and coat."

Another entry read:

"Sorina Dobre says she woke in the churchyard with no memory of walking there. Father Andrei Popescu found her at dawn, kneeling before a grave sealed for fifty years. There was soil beneath her fingernails."

The entries became frantic.

"We are all having the same dreams. Three heads on one body, too many arms, eyes where eyes should never be. The children draw them constantly. Lidia Barbu will not stop crying. She says the shadow people are coming for the harvest."

Dru read over my shoulder. "Mass hysteria."

"Keep reading," I said, although my hands had begun to shake.

"The animals left first. Every dog, cat and rat vanished overnight. Then the birds. Now it is so quiet that we can hear our own blood moving. Father Andrei Popescu says it is demons, but demons do not leave geometric patterns burnt into wheat fields. I found them this morning. Perfect triangles and circles. The grain was fused into glass."

The next pages contained sketches of intersecting circles, triangles and lines. At first they looked like idle doodles. The longer I studied them, the more my eyes watered. The patterns appeared to rearrange themselves whenever I looked away, forming structures that could not exist in three-dimensional space.

"Found these burnt into Gheorghe Stan's wheat field. Perfect angles. Impossible angles. During Father Andrei's special prayers, forty people heard singing above the church. Not hymns. Something mathematical, as if geometry had found a voice."

More drawings followed. The innkeeper had placed Carta at the centre of converging lines, like a fly trapped in a web. Numbers ran along the margins, perhaps coordinates or measurements, repeatedly crossed out and rewritten as he tried to solve an equation he did not understand.

"The children knew before the rest of us. They drew the things with three heads. I kept the pictures and wrote their names on them. Lidia Barbu. Radu Stan. Anca Voinescu. Every child drew the same creature, down to the fingers on each hand. Seventeen. Always seventeen."

The final entries were scarcely legible.

"They are not lights. They are eyes. God help us. They see everything. They know we are here. They have always known.

"The children disappeared during morning prayers. Thirty-four pupils vanished between the opening prayer and the next response. Most parents now insist that they never had children, but some of us remember. The forgetting spreads like sickness. I am writing their names so someone will know."

The list continued for two pages.

The last sentence ended abruptly: "The harvest comes and we are-"

The ink trailed across the paper as though the writer had been interrupted or dragged away.

"Movement in the church." Nadia's voice cut through the radio static. "Thermal registered something for about three seconds."

"On our way."

I closed the journal, then put it in my pack. It was evidence, or proof that I was not losing my mind.

"Dru, with me. Nadia and Marta, hold the pensiune."

The church door stood wider than it had before. I was certain of it. The drag marks in the soil had not changed, but the opening had widened from a narrow gap to one broad enough for a person to pass through.

Dru checked her equipment. "Nothing now. There was a clear return, though. The thermal image looked like a cold mirage."

We entered together with our weapons raised. Our boots echoed on the stone. Orthodox icons watched from every wall, but every face had been altered. The eyes of each saint, angel and depiction of Christ had been scratched away. It had not been done violently. The cuts were careful and precise, made by someone with a sharp tool and a steady hand.

"Recent?" I asked.

Dru examined the nearest icon. "No dust in the grooves, but the exposed wood has oxidised. Perhaps two weeks old. It happened after the blackout began."

Symbols had been carved deeply into the ancient altar. They matched the geometry in the journal. The marks seemed to pulse at the edge of my sight, yet remained motionless whenever I looked straight at them. My camera could not settle on a focal plane. Its autofocus hunted backwards and forwards as though the carvings occupied several distances at once.

"Document everything," I said, although every instinct urged me to leave.

"Imogen." Dru had reached a side door. "The priest's quarters."

The small room beyond resembled the cell of a man recording his own descent into madness. Biblical passages covered the walls in what my mind insisted was red paint, although the copper smell suggested blood. Most came from Revelation, particularly the descriptions of angels that were not remotely human, beings of wings, eyes and thunderous voices.

Other texts had been added among them. Some appeared to predate modern Romanian, perhaps even Roman occupation. Others were entirely unknown to me: mathematical sequences that hurt to follow and star charts depicting constellations that did not exist.

Across the ceiling, one passage had been written larger than all the rest.

"And they had faces before and behind, and wings that were eyes. And their voice was the sound of many waters, saying: The harvest comes. The harvest comes. The harvest comes."

"The mission report is going to be interesting," I muttered as I photographed it.

"Do you think anyone will believe this?"

"I don't believe it, and I'm looking at it."

Behind the door, Dru found pages torn from different books and pinned to the wall with rusted nails. Some contained anatomical drawings of creatures that were not human, although recognisably human parts had been incorporated into them. Others displayed mathematical proofs that seemed to establish the impossibility of their own existence.

We recorded every unique piece of evidence and returned to the pensiune as darkness settled over Carta. In the half-hour we had been inside the church, the temperature had fallen by 10 C. Our breath clouded in front of us.

Marta met us at the door, pale and wide-eyed.

"I saw figures in the forest. Multiple heat signatures moving in formation."

"How many?"

"Twelve, perhaps more. But when I looked through the optical sight, there was nothing. Thermal showed them clearly. The visible spectrum showed empty forest."

Security drills took over. We withdrew inside, established overlapping fields of fire and arranged two-hour watches. Nobody was to leave alone.

While Nadia and Marta prepared sleeping positions, I spread our photographs and notes across the bar. Dru picked up the innkeeper's sketch of the three-headed creature, its body a tangle of limbs that bore little relation to human anatomy.

"My Welsh grandmother used to tell us about an emptied mining hamlet in Snowdonia," she said. "Her own grandmother claimed that things came down from the sky one winter and took everyone. The buildings were left empty. There were burn marks in the ground, all laid out in patterns."

"Folklore," I said automatically, but the word sounded hollow.

"Yes. Folklore."

She set the sketch beside the photographs from the school. The resemblance was undeniable: the same three heads on serpentine necks, the same impossible arrangement of limbs, the same eyes placed where eyes should not be. Different children, different ages and different levels of ability had produced the same creature.

"It could still be mass hysteria," Dru offered without conviction. "A shared delusion passed down through the village."

"Your grandmother's story was from another country, and the priest copied texts older than Carta."

We stared at the evidence. Military training taught us to trust only what we could verify, but everything before us defied verification while remaining undeniably real.

At 2200, I attempted our scheduled check-in. The radio returned only static with the same slow rhythm Marta had noticed. It resembled breathing through a ventilator, or something enormous inhaling and exhaling in the dark.

"Atmospherics," I told the others, seeing my doubt reflected in their faces. "We'll try again at 0000."

Nadia took first watch while the rest of us tried to sleep. I lay on a dusty sofa listening to the building settle. Old timbers creaked in patterns that almost became footsteps. Through the window, the stars appeared too bright and too close. The radio continued its rhythmic pulse: in and out, in and out, like something vast and patient waiting beyond the limits of perception.

A scream tore me from sleep. I rolled from the sofa with my rifle in hand before my mind had caught up with my body.

Marta stood at the window. Her mouth opened in a second, soundless scream as she pointed outside.

Red light flooded the pensiune.

It was the impossible red described in the journal, neither fire nor flare nor anything I could name. It passed through the walls as though they were not there, throwing shadows in the wrong direction. Its pulse made my teeth ache.

"Everyone, full kit. Now."

I seized my body armour, fumbling with the fastenings. Dru was already moving, but her night-vision equipment sparked and died when she switched it on. The radio on Marta's pack emitted a high shriek that bored into my skull.

I checked my analogue watch. Its hands had stopped at 03.17. The second hand twitched backwards and forwards, fighting an invisible restraint.

The red glow intensified until the dining room looked soaked in fresh blood. Through the window I saw that it descended directly over the village square. Looking towards its source hurt like staring through crimson glass at the sun.

"It's happening," Dru said. "Just like the journal."

Her words died as Nadia walked past the window.

She was not running towards a threat or seeking cover as we had trained a thousand times. She walked slowly into the square, arms hanging loose, her face raised towards the light.

"Nadia, get back inside."

I wrenched open the door. The metal handle burnt cold against my palm.

"That's an order!"

She did not react. She stopped in the square, her skin made ruby-red by the light. Her eyes reflected it like mirrors, sending it back at angles that made my vision swim.

I ran outside. The air was thick and electric, tasting of copper and ozone. I grabbed Nadia by the shoulder and shook her.

Nothing. Every muscle in her body was locked. I put my weight behind the effort, but she would not move. It was as though her boots had fused to the cobbles.

"Nadia, snap out of it."

Footsteps sounded behind me. Dru walked past with the same mechanical stride and upward stare. The light seized her three metres from Nadia, and her body became rigid.

"Dru, no."

I lunged for her, but touching her was like grasping stone. Her skin was too cold and too hard, vibrating at a frequency I felt inside my bones.

The pulsing accelerated. The light no longer merely illuminated them. It penetrated their bodies like an X-ray. Nadia became translucent. I could see the cobbles through her, with the dark shadows of her bones suspended inside fading flesh.

"Christ."

I staggered back. "Nadia, Dru, fight it!"

They were dissolving. There was no other word. Each pulse erased another layer of them. Nadia's rifle slipped through her vanishing hands and struck the ground with a sound that seemed to come from kilometres away.

Movement showed in the doorway. Marta stood silhouetted against the darkness, one foot raised to step outside.

The journal had been clear about the people who walked into the light. I moved on training and desperate instinct, tackling her with my full weight. We crashed backwards into the pensiune.

Marta gasped as we struck the floor. Whatever had possessed her broke.

"Stay inside."

I kicked the door shut, although the red light passed through the wood unhindered.

"The cellar. Move."

Through the window, I watched the last of Dru disappear. Her helmet, vest, rifle and equipment fell through empty air, striking the cobbles one after another like a countdown. Then there was nothing where she had stood, not even dust.

Nadia lasted three seconds longer. Her face was the last part to fade, her mouth open in what might have been a scream or a prayer. Her mirrored eyes reflected red until there were no eyes left to reflect anything.

"No. No, no."

I pressed against the glass, searching for some trace of them. Their equipment remained scattered across the square, but my soldiers and friends were gone. My chest seemed to collapse, and my lungs forgot how to work.

Nadia and Dru were the family I had chosen, the only people who understood what we had endured together. They had been erased as though they had never existed.

I struck the window frame with my fist. Pain shot through my arm. It was good. It was real, something that still made sense.

Marta caught my arm and dragged me towards the cellar stairs. I could not think beyond Nadia's dissolving face and Dru's body turning transparent. They were my patrol. My responsibility.

I had failed them.

"Imogen." Marta's grip bruised my arm. "Imogen!"

I still had one soldier left to protect. Training forced my grief into a box to be opened later, if there was a later.

We stumbled into the cellar, descending beyond the strongest light. I could still feel it pressing through the floorboards above. The room smelt of centuries of stone and dust. A small window near the ceiling admitted a shaft of crimson, painting a red rectangle on the opposite wall.

We huddled in the corner farthest from it. Marta held her rifle like a talisman.

"What's happening?" Her voice remained steady, but her body shook against mine. "Where did they go?"

"I don't know."

The pulse above quickened like a heart nearing its limit. Even underground, the light found paths through cracks in the boards, around the doorframe and through the window. It intensified until closing my eyes made no difference. Red blazed through my eyelids and through the hands I pressed over them.

The cellar window exploded inwards without an impact. The glass simply ceased to exist, leaving a perfect rectangular opening. Light poured through like liquid and spread across the floor towards us.

Marta gripped my hand.

"Our Father, who art in heaven..."

The light reached us, and she suddenly weighed nothing. Something began pulling her away, not by her limbs but by the space she occupied. I held on until my muscles screamed, but retaining my grip was like trying to hold water.

"Imogen." Her voice stretched and warped. "Please."

Her fingers did not slide from mine. They passed through them as Marta lost material form, translated into a state I could neither grasp nor follow.

I reached again and caught only air.

The red light flared. Marta vanished in the middle of the prayer, her voice cutting off between "hallowed be" and "thy name".

The light went from red to white and then to nothing. Every nerve in my body fired. I tasted metal, smelt burning ozone and felt as though my bones were trying to crawl out through my skin.

Darkness rushed in. I fell towards it, grateful for the emptiness that swallowed me.

The cellar floor was cold against my cheek and gritty with dust that tasted of rust when I breathed. My skull felt packed with cotton, my thoughts moving through treacle.

Marta was gone. I had watched her become insubstantial and felt her fingers pass through mine. The memory struck like a blow.

There was only my breathing and a low humming in my ears, like the sound beneath high-voltage cables.

I forced myself upright. Every muscle protested. The cellar looked wrong. Purple-tinted light entered through the empty window frame, like morning seen through coloured glass, although no glass remained.

My watch was still stopped at 03.17. The radio was dead, the night-vision equipment ruined and my torch would not light, though the batteries rattled when I shook it. Only my grandfather's compass showed any movement. Its needle spun endlessly, searching for north in a world that no longer possessed one.

The wooden stairs groaned beneath my boots. Every step disturbed clouds of dust that should not have existed. We had been down there for hours at most, but the dust suggested years, perhaps decades. Time felt loose and slippery, impossible to hold.

The pensiune's dining room stopped me cold.

Everything had aged a century. The bar where we had spread our maps was a skeleton of rotten wood. Bottles stood on the shelves beneath green mould that pulsed faintly in the purple light. Wallpaper hung in strips like dead skin. The walls beneath it looked organic, veined and damp.

The sofa where I had slept had collapsed inwards, its springs protruding through fabric that disintegrated under my fingers. All our equipment was gone. Every trace of my patrol had vanished. Even the dust on the floor preserved no footprints but mine.

The front door hung from one hinge. I pushed through it, and the impossibility outside struck with physical force.

Carta had become a corpse.

Buildings slumped as though they had been melting for decades. Roofs had caved in, and walls bulged outwards. Black thorned vines as thick as my arm strangled the ruins, growing through windows and bursting from doorways. Their thorns gleamed like obsidian. The vines pulsed with a slow heartbeat that made my skin crawl.

The sky was a bruise-coloured purple. There was no sun and no cloud, only a sick light coming from everywhere and nowhere. The air was thick as syrup and coated my throat with every breath. It tasted of pennies and battery acid.

A house across the square had split down the middle, its halves leaning apart like a broken wishbone. Through the opening I glimpsed an interior that defied physics. Rooms were stacked vertically. Furniture clung to walls. A staircase spiralled into nothing.

My boots crunched over what I first mistook for gravel. It was composed of tiny bones, thousands of them, belonging to creatures I could not identify. They had been arranged into deliberate patterns along the street. Looking directly at those patterns made my eyes and thoughts ache.

The church drew me towards it, although every instinct demanded that I run. Its stone walls had partly liquefied, flowing like candle wax before freezing in mid-drip. The bell tower twisted into a spiral that should not have supported its own weight, yet it remained standing in contempt of everything I understood about physics.

Inside was worse.

The icons we had photographed had changed. The saints now possessed multiple screaming faces. Their halos had become geometric figures that shifted whenever I looked away. Christ had grown additional arms upon the cross, each hand pointing towards an exit that did not exist in normal space.

The altar had sprouted. No other word fitted. Black branches grew from the carved symbols and reached towards the melted ceiling. They dripped a fluid that hissed whenever it struck the floor.

A sound outside made me freeze.

Heavy footsteps approached, but the rhythm was wrong. There were too many legs, moving unevenly, like something still learning to walk. Then came breathing, wet and laboured, as though its lungs were filled with fluid.

I crept to a window and looked through warped glass that distorted the square like a fairground mirror.

What I saw made my mind refuse the evidence for several seconds.

The thing stood three metres tall, perhaps more. It was difficult to judge because its proportions kept shifting. Three heads rose on necks that moved like snakes, weaving independently. Each face was almost human, but stretched into something subtly and profoundly wrong.

Its body was worse. I still do not know how to describe it properly. Flesh and exposed bone had been twisted together, its ribs forming an external cage around organs that glowed faintly purple. Arms sprouted from its torso at angles that made me nauseous. Each ended in a hand with too many fingers, or fingers with too many joints.

It moved through the square with purpose, its three heads scanning in different directions.

Others followed it. Some walked on two legs but had reversed torsos, with faces set where their backs should have been. One crawled on dozens of human hands, its body a mass of writhing flesh. Another looked almost normal until it turned and I saw that its skin was covered in human eyes. Hundreds of them blinked in perfect unison.

They were searching.

Their movements followed a pattern, systematic and thorough. The three-headed creature gestured with one of its many arms, and the others spread out to inspect buildings and peer through windows.

I pressed myself against the church wall and did not dare breathe.

One of the eye-covered things passed directly outside my window. At that distance, I could see that its eyes were different colours: blue, brown, green and grey. For a moment they all turned towards me. Each iris contracted in sequence, a wave of recognition that never quite completed, and then the creature moved on.

Hours passed, or minutes, or days. Time had no meaning in that purple hell.

The creatures continued their search, occasionally calling to one another. They did not use words. Their voices were mathematical tones, as though equations had learnt to speak.

At last they moved towards the forest and disappeared among trees growing in impossible directions. Some stood sideways. Others hung upside down, with roots and branches impossible to distinguish.

I waited until my legs cramped and the purple light deepened, although no true night fell. Then I crept from the church to the pensiune, moving between shadows cast in the wrong direction.

In the kitchen pantry, I found tins of food that had somehow survived the decay. The writing on their labels changed whenever I looked away: Romanian became Russian, then symbols that did not belong to any alphabet I knew. The contents tasted of copper, batteries and ash, but my stomach accepted them.

Water still ran from the taps, thick and oily. It burnt my throat. The first time I drank it, I vomited at once. The next time, I kept it down for nearly an hour. Eventually my body adapted, or I became something capable of digesting whatever it was.

I barricaded myself in the cellar with furniture from upstairs. Much of the wood crumbled beneath my hands, but it offered the illusion of a barrier. Through the empty window frame, purple light pulsed with its own rhythm. Sometimes I heard the creatures calling to one another in their equation speech.

My patrol was gone. Carta was gone. The world itself seemed to have vanished, replaced by a nightmare in which physics had gone to die.

Yet I was alive. Somehow, impossibly, I was breathing wrong air beneath a wrong sky. Somewhere beyond the cellar, those things were still searching. I did not know what they wanted, but I had a sick certainty that it was me.

I turned the cellar into something resembling a base. Tins lined one wall. I used the innkeeper's journal to record patrol routes, observations and tally marks representing what I called days, though I labelled every count as an estimate. Even the marks felt dishonest beneath a sky that neither brightened nor dimmed.

My body insisted that time was passing. Stubble grew on my legs. I lost weight until my uniform hung loosely from me. By my estimate, I had been there more than two weeks.

The creatures moved in patterns. Using pulse counts, breathing drills and long sequences of "one thousand, two thousand", I estimated that the three-headed creature crossed the square from east to west every six hours. Roughly two hours later, the crawler made of hands circled the buildings anticlockwise. The eye-covered thing followed no pattern I could identify, but remained close to the church.

They entered most buildings. They never entered the primary school. Nor did they approach the forest paths leading away from the village.

On what I called day twelve, I tried to leave by the main road. It should have taken me to the clearing where Warrant Officer Lucian Ionescu had put the helicopter down, three kilometres from Carta.

I walked for three hours with the purple forest pressing in on both sides. Black vines pulsed with their own heartbeat. Trees grew horizontally, twisted into corkscrews or thrust their roots upwards while their branches burrowed into the ground.

The road ended at Carta's entrance.

The same abandoned vehicles waited there, including the battered Dacia Logan. The same buildings decayed beneath the bruised sky. I had walked directly away from the village and arrived back where I had started.

I tried again, marking trees with my knife. An hour later, I found the marks, but approached them from the opposite direction to the one from which I had carved them.

The forest paths were worse. A northern trail brought me into Carta from the south. Walking backwards delivered me to the church. I could face east, walk west and find myself outside the pensiune. The geometry was not merely wrong. It was actively hostile to reason.

I filled pages of the journal with diagrams. Some routes worked only if I did not look towards my destination. Another required me to close my eyes and take exactly one hundred steps. One path allowed me through only when I crawled.

By my estimated fifteenth day, I had accepted the truth. Carta existed inside a bubble of distorted space, and there was no exit governed by rules I understood.

The school basement door had been locked during our original sweep. Now it stood open, with darkness yawning beyond it.

I had avoided it for days because every instinct warned me away. But my supplies were running low, and I had searched everywhere else.

The stairs descended much farther than the dimensions of the building allowed. My torch had been dead since the red light, so I navigated by the purple radiance seeping from the air itself.

The walls became organic. They resembled the inside of a throat and pulsed faintly beneath my hand, warm to the touch. The smell reached me first. It was not decay, but ozone, copper and something cloyingly sweet.

Then I saw her.

"Marta."

My voice broke on her name.

She was not standing against the wall. She had been deposited inside it. Her back and left side merged with the pulsing surface. Her face turned towards me and her eyes tracked my approach, but her lips had fused into an unbroken seam.

Seven additional arms sprouted from her torso. Each was perfectly formed and completely wrong. They moved independently, their fingers grasping at the air and shaping gestures like a form of sign language devised for dimensions beyond our own.

"Marta, hold on."

I reached for her, trying to find the boundary between her body and the wall. The instant my fingers touched her skin, the world exploded.

I saw thousands of villages across an infinity of Earths. Over each came the red light. People walked into it and their bodies dissolved into useful matter.

It was a farm spanning parallel worlds.

The creatures were not monsters. They were farmers.

We were the crop.

I watched Nadia Price dissolve again, but this time I saw where she went. She had not been destroyed. She had been translated, processed and broken into components for which I had no language, then sorted and stored in structures outside three-dimensional space.

I saw Dru Bennett as well. Her consciousness was extracted and catalogued. Her body was repurposed into something else.

The visions accelerated. Earth after Earth appeared, each at a different stage of harvest. Some remained green, blue and ignorant. Others were empty, their dead cities lying beneath purple skies. A few had learnt to fight with weapons that bent reality, but they always lost. In the end, every world was harvested.

The farmers had been doing it for a span my mind could not express as a number. The concept forced into me meant always, forever and longer than matter itself had existed.

We were not special. We were not unique. We were one crop among infinite fields.

The vision released me. I collapsed to my knees and vomited oily water across the basement floor.

Marta watched me with something that might have been pity, warning or both. All nine of her hands moved. Seven traced patterns while the two that had always been hers dragged their fingers slowly and carefully through the dust.

BLUE LIGHT. FOREST. ESCAPE.

Tears ran down cheeks already partly absorbed into the wall. Even then, she was trying to save me.

"I can't leave you like this."

Her original hands formed a gesture I knew from a hundred operations.

Go now. That is an order.

I took tins from my pack and bottles filled with the terrible water and placed them within reach of her hands. It was probably useless. I did not know whether she could eat or drink, but I had to do something.

"I'll come back," I lied. "I'll find help."

One of her new hands waved, almost cheerfully, its fingers waggling as if saying goodbye to a child. Another pointed urgently towards the stairs.

The creatures were coming.

I heard their wet breathing above us.

I ran up the impossible staircase, through the school and out of the rear door just as the three-headed creature entered at the front. I plunged into the purple forest, where trees grew sideways and up could become down without warning.

BLUE LIGHT. FOREST. ESCAPE.

Marta had given me a mission, the final order issued by anyone in my patrol. I would obey it, even if it killed me. Remaining in that cellar beneath another endless pulse of purple light was killing me already.

Somewhere in the impossible forest, there was blue light. There was a way out. I only had to survive long enough to find it.

The forest became my world: purple sky above, black vines below, and me between them, weakening through whatever passed for days.

I mapped approximately eleven square kilometres of impossible terrain in the journal and in my head. The three-headed creature crossed what I had labelled grid Alpha Seven at intervals of roughly six hours. The hand crawler preferred the eastern slopes, where trees grew upside down. The eye-covered creature never moved more than two hundred metres from the church, as though tethered to it.

My body began to fail around my estimated twentieth day. Clumps of hair came away in my hands. Brown hair, the colour my mother had given me, littered the purple forest floor. What grew in its place was brittle, pale and rapidly turning white.

I saw it in puddles of thick water, although each puddle showed four versions of me rather than one.

My fingernails turned black around the twenty-fifth day. They were not bruised or stained. The colour resembled ink driven down into the bone. I scraped at one with my knife until blood rose around the blade, but the blackness extended deeper than I could reach.

Some time after my thirtieth tally, I found the ravine.

It should not have existed. I had walked that route many times, marking trees and memorising every twisted trunk. Yet a gash twenty metres wide now split the earth. Its walls were exposed rock gleaming like oil under the purple light.

The smell was older than decay. It was like opening a tomb sealed before human beings learnt to write.

My analogue watch, which had stopped at 03.17 during the red-light event, had begun moving again after my search for the blue light started. The hands advanced normally, but I no longer trusted what they measured. At best, it helped me estimate the creatures' intervals.

I climbed into the ravine. My boots found purchase, although the rock was warm and slightly soft beneath them, like skin.

Halfway down, I saw the skeletons.

There were dozens, perhaps hundreds, but they had not been scattered or buried. They were fused into the rock in perfect spirals. Femurs twisted into helices. Ribcages opened like flowers. Skulls formed a pattern that made my eyes water when I tried to follow it.

Something metallic lay inside one skull. I worked it free with my knife while the bone crumbled like chalk.

It was a corroded British Army identity disc.

PRIVATE ALASTAIR JAMES MCRAE 22468193 CHURCH OF SCOTLAND 1952

The disc felt far heavier than it should, as though it carried the weight of McRae and everyone who had vanished with him. This place had been taking people for generations.

How many had reached this purple world? How many had dragged themselves through its forests in search of an escape that never came?

I put the disc in my pocket and continued searching. More bones emerged from the rock, some far older and not entirely human. There were skeletons with too many ribs, femurs jointed in the wrong places and a skull with three sockets arranged in a triangle.

Once I understood what I was seeing, the rock became a record. Layer upon layer marked successive harvests. The bones were not random. They formed a monument to everything taken and processed there.

The place had been operating since before humanity possessed words for it.

My legs failed around my estimated thirty-fifth day.

It happened gradually. First my left knee stopped locking properly. Then my right ankle began to bend in directions no ankle should. I cut a branch to make a crutch. It bled black sap that burnt my palms before hardening into a resinous grip.

By roughly day thirty-eight, I could no longer walk. The bones in my legs felt soft, as though they were being reshaped into something new. I crawled through purple dirt that tasted of copper whenever it entered my mouth.

My uniform, already worn almost to threads, finally disintegrated. The fabric dissolved, leaving me in my underwear and boots, which somehow remained intact.

The creatures grew curious. I saw them at the edge of my vision, keeping their distance but watching. Whenever the three-headed thing spotted me, all three heads tilted like a dog trying to understand speech. Once, the hand crawler approached within ten metres. Dozens of fingers drummed the ground in a rhythm almost like Morse code.

They knew I was dying, or changing. Perhaps, in that place, those were the same thing.

Around the fortieth tally, if any of my estimates meant anything, I saw it.

At first it was only a glimmer, so faint that I thought my sight was failing.

Blue light.

It was clean, sharp and utterly alien against the purple world. It came from deeper in the forest, beyond a grove whose trees formed perfect mathematical spirals.

I crawled towards it. Every metre lasted an eternity. My body screamed its objections in languages I did not recognise. Black vines tangled around me, their thorns tearing skin that no longer bled red. The fluid was dark and viscous, like the water from the pensiune taps.

The blue light strengthened as I approached. Unlike the constant purple sky, it flickered unsteadily, like a fluorescent tube about to fail.

A clearing opened ahead.

A fracture hung in the air, roughly one metre high and fifteen centimetres wide, its edges fraying with static. Through it I saw fragments of a normal sky: blue, moving clouds and a sun that looked like a sun.

Home, or at least somewhere that was not there.

I dragged myself forwards, black fingernails clawing through the earth.

Branches snapped behind me. Wet breathing filled the forest.

They had found me. All of them were converging.

Twenty metres remained. My right leg was entirely numb and dragged behind me like dead meat.

Fifteen metres.

The three-headed creature burst from the trees on my left. Every mouth opened, revealing human molars arranged in geometrical patterns of triangles and hexagons.

Ten metres.

The crawler scuttled in from my right, its fingers reaching and grasping. Some wore wedding rings that caught the blue light.

Five metres.

The eye-covered creature stood in my path. Hundreds of eyes wept blood which flowed upwards in defiance of gravity.

I lunged for the fracture.

The three-headed thing moved with impossible speed. One of its hands closed around the ankle in which I could still feel pain. It had seventeen fingers.

Its grip burnt with a cold like dry ice. I kicked with my useless leg. The bones bent wrongly, but my boot struck something that might have been its knee. The creature released me, more surprised than injured.

I threw myself towards the blue light and gripped the ragged edges of reality.

The sensation was like seizing a live electrical cable while drowning in ice water and feeling every bone turn to glass. Every atom in me screamed to let go.

But letting go meant remaining there. It meant becoming like Marta, conscious inside a living wall.

I pulled.

The opening was too narrow. My shoulders compressed. Bones ground together and skin stretched as though heated. My body tried to exist in two dimensions at once, some parts remaining in the purple forest while others entered whatever waited beyond.

My vision divided. One eye saw the forest. The other saw the blue sky.

Behind me, the three-headed creature thrust an arm through the fracture. It lengthened impossibly, seventeen fingers brushing my back. Wherever they touched, I felt my cells forget how to remain joined.

But most of me was through.

With one final pull, muscles tearing and joints wrenching from their sockets, I forced myself across. Blue light flared brightly enough to burn through my closed eyelids.

The creature's hand remained in the fracture when reality snapped shut. It was severed at the wrist and fell back into the purple world, twitching, all seventeen fingers grasping at nothing.

Then the blue consumed everything.

I fell into light that tasted of coming home and dying at the same time. Across the closing gulf between dimensions, I still sensed the three-headed creature standing before the sealed fracture.

All six of its eyes were human. I recognised Nadia's brown eyes and Dru's hazel ones. The other four belonged to people I had never known. They wept blood upwards into the purple sky.

The harvest would continue, but it would not take me. Not that day.

The blue light carried me away. My body stretched across dimensions like paint smeared over canvas. I felt myself disassembled and put together again, but wrongly, never fitting quite into the space I was meant to occupy.

Behind me, the purple world pulsed with its alien heartbeat. Ahead, Earth waited.

If I survived the passage between them, I awoke with leather restraints biting into my wrists.

The Romanian military hospital in Bucharest smelt of bleach and old cigarette smoke. The combination made my empty stomach contract. My throat felt lined with sand, and my tongue was thick and swollen.

Colonel Harriet Ashcombe sat beside my bed. Her uniform was immaculate, but her face looked drawn. Dark circles lay beneath her green eyes.

"You were missing for seventy-two hours," she said. "We found you unconscious in Carta's village square. Three days, Imogen."

The words would not settle into meaning. I had spent weeks beneath that purple sky. I had marked each estimated day in the innkeeper's journal. My legs had failed. My hair had fallen out. I had crawled through a dimensional fracture on softening bones.

"No," I managed. My voice was cracked and scarcely recognisable. "Longer. Much longer."

Colonel Ashcombe's expression remained controlled, but something shifted behind her eyes. She knew, or at least knew that seventy-two hours could not account for what had happened to me.

"The medical team says you're severely dehydrated and malnourished." She glanced at the chart. "Your blood results contain anomalies, but in this world you were gone for only three days."

I tried to sit up, but the restraints held me.

"Why am I tied down, ma'am?"

"You were combative when they brought you in. You kept screaming about red lights and three-headed creatures. The sedatives eventually calmed you."

Memory struck in a single crushing wave: Nadia walking into the red light, Dru losing material form, Marta embedded in the wall with seven new arms.

My chest tightened until breathing hurt.

"My patrol."

"I'm sorry," Ashcombe said, and for a moment her voice softened. "Sealed, badly contaminated remains were recovered yesterday."

"That's impossible."

The words escaped before I could stop them.

"Nadia and Dru dissolved. Marta was translated in the cellar and deposited somewhere else. I saw it happen."

Colonel Ashcombe rose and smoothed her uniform.

"The exposure caused severe hallucinations. You're fortunate to be alive, Captain Vale."

"Exposure to what?"

She placed an official report on the bedside table. The paper felt obscenely normal after everything I had touched in the other place.

I scanned the typed words. They formed a carefully constructed lie: an alleged leak of Soviet-era organophosphate nerve agent from an abandoned depot, producing hallucinations, seizures and fatal respiratory failure. Three personnel dead. One survivor recovered in critical condition. Sealed contaminated remains recovered and prepared for repatriation.

"There was no nerve agent. There was a dimensional shift. A purple world. Those creatures-"

"Captain."

Her tone cut through me, professional and final.

"You have suffered severe trauma. Your mind is attempting to impose meaning on it."

"You know this report isn't true."

Her jaw tightened.

"What I know is that three soldiers are dead and you are alive. The official investigation is complete."

"Investigation? You're simply going to-"

I stopped when I saw the warning in her eyes.

Not here. Not then.

There was a dark observation window in the far wall.

Ashcombe bent to adjust my intravenous line and lowered her voice to almost nothing.

"Play along, Captain. For your own sake."

Then she straightened and spoke for whoever was listening.

"The medical team will continue monitoring you. Defence Intelligence will debrief you when you are stable."

She left without looking back.

The interviewers arrived six hours later. Mr Callum Reed and Mr Tariq Mahmood wore plain suits and displayed Defence Intelligence credentials. They asked the same questions repeatedly.

Tell us about the mission. Describe what you saw. How did you survive when the others did not?

At first, I told them the truth. I described Carta frozen in the middle of ordinary life, the red light that had removed my patrol, the purple dimension in which geometry turned hostile, and the three-headed creature with too many arms. I told them about Marta in the school basement, spelling a warning with hands that should not have existed.

They took notes without visible reaction.

Reed produced a tablet.

"This is satellite imagery from three days ago."

He turned the screen towards me. It showed Carta during the period when I had been crawling through the purple forest. The streets and buildings appeared normal. Romanian personnel walked past houses beneath an ordinary sky. There were no black vines, no melting church and no purple light.

"That's impossible."

"The mind can construct elaborate scenarios under extreme stress," Mahmood said, "particularly after organophosphate exposure."

"There was no nerve agent."

Reed displayed another photograph. Three sealed body bags were being loaded into a medical transport.

"Your patrol members were found in the church," he said. "The official findings are consistent with exposure to a Soviet-era organophosphate nerve agent. You were recovered twenty metres away, unconscious but breathing."

"I watched Nadia and Dru disappear. Marta was taken in the cellar."

"You witnessed your personnel die during a chemical incident," Mahmood said. "Your mind constructed another narrative to protect you. Dissociation in survivors is well documented."

I laughed. The sound was bitter and broken.

"And my hair turning white?"

"An extreme stress response."

I held up my hands.

"My nails?"

"Tissue damage associated with the alleged exposure. It may resolve with treatment."

They had a tidy answer for everything. None included parallel Earths, harvesting or the fact that humanity was one crop among infinite fields.

"I want to see the bodies."

Reed and Mahmood exchanged a glance.

"That isn't advisable," Mahmood said. "The remains are severely contaminated. The coffins will remain sealed."

Of course they would.

The questioning continued for hours. Whenever I spoke of the purple world, the creatures or its impossible geometry, they redirected me towards hallucination, trauma and survivor's guilt.

At last Reed leant back.

"Captain Vale, you need to understand the consequences of continuing to make these allegations publicly. You could face compulsory psychiatric assessment and medical discharge. Your service-related compensation may be reviewed."

"Is that a threat?"

"It is the reality of your position," he said.

Mahmood closed his notebook.

"Alternatively, you can accept that you survived a tragic incident involving an alleged Soviet-era nerve agent. You will receive appropriate recognition, continuing medical care and support through your transition to civilian life, should discharge prove necessary."

The choice hung between us. Insist upon the truth and be confined, discredited and stripped of my remaining independence, or accept the lie and walk away.

"I need time to think."

They left me with the report.

I read it again and memorised every detail of the fiction I was expected to endorse. Soviet-era organophosphate nerve agent. Three dead. One survivor. Nothing about farmers outside dimensional space. Nothing about human beings as crops.

My pack had been confiscated, along with the innkeeper's journal and Alastair McRae's identity disc. I never saw either again. As soon as I was able, I began reconstructing the journal from memory, reproducing its entries, my maps and every observation I could recall.

That evening, Colonel Ashcombe returned with a civilian doctor in her thirties carrying a medical bag.

"This is Dr Priya Nair," Ashcombe said. "She will conduct your psychiatric evaluation."

Dr Nair had intelligent, watchful eyes. She drew up a chair with careful, deliberate movements.

"Captain Vale, I specialise in trauma recovery among service personnel who have experienced unusual events."

She glanced towards Ashcombe.

"Could we have some privacy, Colonel?"

Ashcombe hesitated, then left. Dr Nair waited for the door to close.

"Those restraints must be uncomfortable. May I?"

She began undoing them before I answered.

"There. Better."

I rubbed my wrists and studied her.

"You don't believe the nerve-agent report."

"What I believe is not yet relevant. What matters is helping you process what happened."

She took out a paper notebook rather than a tablet.

"Tell me what you remember. All of it."

So I did.

I described the purple sky, the creatures and the distortions of time and space. I told her about Marta in the wall, the global harvest across parallel worlds, the fracture in the forest and the creature's severed hand falling back into the purple world as the opening closed.

She wrote without interrupting, asking only for clarification. When I finished, she placed down her pen.

"There have been twelve other incidents in the past five years. Different locations, but elements of the pattern recur. Survivors report impossible events, then accept an official explanation or disappear into secure psychiatric care."

"You believe me."

"I believe you experienced something that does not fit our present understanding of reality." She leant closer. "The question is what you choose to do with that experience."

Before I could answer, Colonel Ashcombe returned. Darkness had closed around the hospital, and the room felt smaller.

"Time's up," she told Dr Nair. Then she turned to me. "You will be transferred to the Royal Centre for Defence Medicine at Queen Elizabeth Hospital Birmingham. After that, there will be a private remembrance service. The families will attend."

The families.

Nadia Price's grandfather, Ernest Price. Dru Bennett's brother, Owen. Marta Kowalska's parents and younger brother. All of them deserved answers they would never receive.

"I can't face them."

"You can, and you will," Ashcombe said. "You owe them that much."

She was right. I owed them what little closure the official lie allowed.

The service took place after my transfer back to Britain, in a small military chapel. Three Union-flag-draped coffins stood before the altar under strict contamination protocols. Officials claimed they contained sealed remains. I was denied any opportunity to verify that claim, and I believed the coffins were empty or held something that had never truly been my patrol.

Military bearers stood beside them. The chaplain spoke of courage, service and sacrifice. The Last Post sounded through the chapel, followed by silence and Reveille.

Nadia, Dru and Marta received posthumous Mentions in Despatches. I was given an operational gallantry commendation for attempting to save my patrol during the alleged chemical incident. They called me a hero for surviving.

The families wept and held one another. Afterwards, their relatives' personal effects were handed to them in private.

Ernest Price was small, upright and fierce even in grief. He took both my hands.

"Nadia wrote about you," he said. "She said you were the finest commander she'd served under."

I wanted to tell him that Nadia had remained brave until the end. I wanted to explain that she might still exist somewhere, separated into components beyond my understanding and stored outside our dimension.

Instead, I said, "She was the finest soldier I ever served with."

Owen Bennett showed me a photograph of himself and Dru as children on a Welsh beach, both of them grinning into the wind.

"She was meant to come home next month," he said. "We were going to take Mum back to the coast."

Marta's mother spoke little English, so her husband translated.

"Was it quick? Did she suffer?"

"It was quick," I lied.

The truth burnt in my throat throughout the service.

That night, alone in temporary accommodation near Queen Elizabeth Hospital Birmingham, I looked properly into a bathroom mirror.

My hair had grown back entirely white, stark against my olive skin. The face looking at me seemed older and fixed with the stare of someone who had seen too much. In the right light, purple glimmered in my eyes.

I raised my hands and examined the black nails. I scraped one with my pocket knife, but the colour lay deeper than keratin and flesh. It was as though I had been marked, tagged and altered.

There was one clear reflection at the centre of the glass. In my peripheral vision, however, I saw others: two, three, four versions of myself standing at slightly different angles.

Too many faces stared back.

The official account would stand. I would return to Britain permanently, begin therapy with Dr Nair and attempt to construct something resembling a life.

But I knew the truth. We were crops on a farm spanning dimensions. The harvest was real, and it would come again. More villages would empty. More soldiers would walk into red light. More families would sit before sealed coffins and wonder why they could not say goodbye.

Somewhere in a purple world parallel to ours, Marta remained fused into that wall, spelling warnings with hands that should not exist. The farmers continued tending their fields.

I had survived. Somehow, impossibly, I had survived. Now I had to decide what to do with that survival, because knowing the truth and being unable to speak it felt worse than dying beside my patrol in the red light.

I touched the mirror. For an instant, all four reflections moved independently.

The next day I accepted the official account and began treatment. But that night I stood in a military hospital bathroom, counting my reflections and wondering which of them was truly me.

Months later, the medical-supplies distribution depot on Trafford Park stretched before me like a concrete tomb. About 3,700 square metres of industrial shelving and shadow made it ideal for someone who no longer slept properly.

"Night shifts are quiet," the day security officer said as he handed me the keys. "Walk the perimeter every two hours and check the loading bays. That's about it."

Easy money, in theory. Nothing was easy when every emergency exit sign resembled the beginning of the end.

I accepted the keys because I needed the work more than I needed to avoid red lights. My Armed Forces Compensation Scheme payment and ill-health pension did not comfortably cover rent on my Manchester flat, and explaining the end of my military career was harder than pretending to function for eight hours at a time.

The first week passed without incident. I devised patrol routes that kept me away from the exit signs and lowered my eyes whenever I passed the flashing fire-alarm beacons. The depot held gauze, syringes, dressings and other medical supplies that would never see a purple sky.

During the long intervals between rounds, I researched on my mobile, using encrypted connections and temporary email addresses. Missing-person reports formed patterns if one knew what to seek. Entire families vanished from rural homes, leaving meals half-eaten. Livestock were found arranged in geometrical formations. Aurorae appeared at latitudes where they had no business being.

News reports gave each incident a separate explanation: cult activity, gas leaks, mass hysteria. But the pattern remained.

Regional events recurred every sixteen to twenty-two years, and the interval was shortening. It resembled a harvest schedule.

Dr Nair's consulting room smelt of vanilla candles and lies. She sat opposite me with her pen poised over the same paper notebook and the carefully patient expression that psychiatrists must practise.

"How are the nightmares, Imogen?"

"Better," I lied.

We both knew I had not slept for more than three consecutive hours since Romania.

"The medication helps."

She made a note. Dr Nair always wrote, but her eyes conveyed something different from her pen. Whenever I recited the official account, she leant forwards and watched my face as though searching for fractures in a mask.

"Tell me again about the chemical exposure," she said, although we had covered it in every session during the past two months.

"An alleged leak from a Soviet-era depot. Organophosphate agents. Three days of lost time."

The words emerged mechanically, polished through repetition.

"My patrol died from exposure. I survived with significant psychological trauma and physical changes."

She indicated my hair, white beneath the surgery's fluorescent light.

"And the explanation for that?"

"An extreme stress response. The specialists at Queen Elizabeth Hospital Birmingham said it was rare but documented."

She wrote again.

"What about the cellular abnormalities?"

My fingers tightened around the chair arms.

"The Royal Centre for Defence Medicine recorded anomalous cellular changes said to be consistent with exposure to an unidentified source of radiation. No one explained what sort of radiation turns fingernails black or makes a person's DNA appear partly rewritten. They said it would stabilise."

"Has it?"

"Yes."

That was another lie.

If anything, it was worsening. Shapes moved in my peripheral vision and vanished when I turned. Sometimes my reflection lagged half a second behind me. Once, I had reached for a mug and my hand had passed through it before becoming solid again.

Admitting any of that risked compulsory assessment and confinement.

"It has stabilised," I repeated.

Dr Nair put down her pen and leant back.

"Imogen, I have treated service personnel for fifteen years. Post-traumatic stress, combat trauma and brain injuries. Your case does not resemble an ordinary response to chemical exposure. The cellular changes, the precise nature of your symptoms, even the consistency of what the reports call hallucinations - they are too specific and too coherent."

My heart hammered against my ribs.

"I don't understand."

"I think you do."

Dr Priya Nair drew out another file, older than the first and worn soft at the edges.

"I had a patient eight years ago. Sergeant Ewan Mercer, Royal Marines. He had been involved in a classified operation on South Georgia. He came back with white hair, black fingernails and a story about lights in the sky that nobody believed."

The official report blamed contaminated operational ration packs. She slid a photograph across the desk. A young Royal Marine, perhaps twenty-five, stared at the camera with the same white hair and the same vacant eyes I saw in my mirror every morning.

"He took his own life six months later," she said quietly. "He left a note saying they were coming for him. That he could feel them getting closer."

My mouth went dry. "Why are you showing me this?"

"Because I've treated four similar cases during my career. Different units, different locations, but always the same physical changes and always an official explanation designed to close the matter." She leant forward. "All of them are dead except you."

The silence between us grew heavy with implication.

"I can't help you if you continue lying to me," she said. "More importantly, I think you need to find other people who have survived whatever really happened. The isolation killed my other patients. They believed they were alone with an impossible truth."

She wrote something on a prescription pad, but it was not the name of a medicine. It was an email address and a phrase: THE SKY WAS WRONG.

"Send those exact words to this address," she said. "Someone will answer."

That night, at the medical-supplies distribution depot on Trafford Park, I opened my laptop in the security office and created another anonymous email account. Beyond the glass, the loading bays of the 3,700-square-metre warehouse lay dark and silent.

My fingers hovered over the keyboard. Sending the message felt like crossing a boundary. It meant admitting that the official story was false, and that I had never truly left the purple world behind.

I typed: THE SKY WAS WRONG.

The reply arrived twelve minutes later.

IT WAS PURPLE WHERE YOU WERE. RED WHEN THEY CAME. YOU ARE NOT ALONE.

WE REMEMBER TOO.

An encrypted link was attached. I followed it and found dozens of accounts written by survivors around the world. They offered fragments of impossible experiences: a French soldier who had lost his unit in Mali, a Japanese researcher from an Antarctic station, and a Brazilian police officer who had investigated the disappearance of a village in Amazonas.

They all described the same things.

Red lights. Purple skies. Creatures that could not exist. Human bodies that returned altered.

I began recording everything, cross-referencing their accounts against missing-person records, local news archives and declassified reports. The patterns gradually emerged. The incidents were not random. They followed ley lines, occurred during particular astronomical alignments and clustered around areas of intense electromagnetic activity.

Someone on the forum had mapped them and marked likely windows for future events.

Three weeks into my research, a different sort of message arrived.

YOU FOUND PRIVATE ALASTAIR JAMES MCRAE'S IDENTITY DISC.

I SERVED WITH HIM. KOREA, 1953. WE NEED TO TALK.

A photograph accompanied the message. It showed a group of soldiers in Korean War uniforms, their faces pale beneath caps and helmets. One had been circled. He was perhaps nineteen, smiling with the ease of someone who had not yet seen horror.

The file also contained a recent photograph, taken two months earlier. The same face looked back at me, older but nowhere near old enough.

Gordon Shaw lived at a static caravan park outside Inverness, if his manner of existence could still be called living. I drove north from Manchester, following the M6 and then the A9, stopping only at motorway services for bitter coffee and petrol. The journey took roughly seven hours.

Twice, I saw shapes pacing the car from the treeline. They kept perfect speed with me, even when the road was clear and I was travelling at motorway pace. At one service station, the lavatory mirror showed four versions of me.

One was still recognisably human. The other three were at different stages of becoming something else.

Gordon had chosen an old transport cafe on the A9 for our meeting. Its windows were misted with grease and rain, and the place looked as though it had served the same stewed tea since the 1950s.

He sat in a rear corner wearing an old field jacket with the badges removed. Even from across the room, I could see what we shared: white hair, black nails and the fixed stare of someone who had seen too much.

Up close, he appeared to be about seventy. If he had served in Korea in 1953, he had to be approximately ninety-two.

"Dimensional exposure," he said before I had even sat down. He had noticed me assessing him. "It changes the way we age. Or stops parts of it. I'm still trying to understand it after more than seventy years."

He raised one hand. His fingernails were as black as mine.

"Tea?"

"Please."

A waitress brought a pot and two mugs without looking closely at either of us. Gordon waited until she had returned to the counter.

"McRae was a good lad," he said. "Wrote to his fiancee every day. Jean Fraser. Carried her photograph inside his helmet."

He stared into his tea.

"When the lights came, he walked straight towards them. Didn't hesitate. None of them did, except me. I hid while the rest of my unit lost material form."

"Surviving isn't cowardice."

"That's what I've been telling myself since 1953."

He took a worn notebook from inside his jacket. Its pages had yellowed with age.

"I've tracked the incidents ever since. The pattern, the frequency, the escalation."

The notebook contained hand-drawn charts, newspaper cuttings and photographs spanning decades. They documented settlements in Siberia, fishing communities in northern Scotland and Iceland, and remote communities across South America, Africa and Asia.

The details scarcely varied. Lights in the sky. Mass disappearances. A handful of survivors whose bodies came back wrong.

"It's accelerating," Gordon said. "The regional interval used to fall somewhere between sixteen and twenty-two years. Now look."

He opened a folded map marked with red pins.

"Four incidents in the previous twenty months."

"The harvest," I said, remembering the visions Marta's transformation had forced into me.

His eyes sharpened. "You saw the full picture."

"Earth after Earth being cultivated. We're one crop among thousands."

"Millions," he said. "Possibly billions. I've had more than seventy years to assemble fragments from other survivors. The beings that take us exist outside our dimensional framework. To them, we're livestock or a cultivated field. Imagine grain becoming conscious. Would it understand the farmer, or the idea of a harvest season?"

"So we're supposed to accept it? Let them take us?"

"No."

He leant across the table, lowering his voice.

"That's why we're building a network. Survivors who remember. Scientists willing to believe the evidence. Former service personnel who've seen too much to accept the cover stories. There's a gathering next week at a remote site in the north-west Highlands. No mobile signal, no mains electricity and no official record of the place."

He pushed a piece of paper across the table. It bore coordinates, a date and instructions for reaching the Inverness contact point before travelling onwards by local roads.

"How many people?"

"Thirty-nine confirmed survivors. About eighty others: researchers, relatives and former service personnel, including people who've lost someone to the lights."

He finished his tea.

"We're trying to understand the pattern and predict the next harvest sites. Perhaps we'll find a way to resist, though I don't yet know how you fight something that exists in more dimensions than we can perceive."

I memorised the coordinates. Gordon tore the paper into narrow strips, dropped them into his empty mug and soaked them with the dregs of the pot.

"They know about us," he said. "Those of us who survived carry residue from their dimension. It marks us. Makes us visible to them."

He watched my face.

"You've seen them, haven't you? Watching your block of flats."

Cold spread through my chest.

"Shadows that move wrongly," he continued. "Figures in windows that disappear when you turn towards them. They're scouts. They want to know whether we're worth retrieving, whether we've learnt too much and whether we're spreading the truth."

He stood and left several pounds on the table.

"Be careful. The more of us gather, the more attention we attract. But alone..."

He gave a small, defeated shrug.

"Alone, we lose our minds and die."

When I returned to Manchester that night, they were waiting for me.

Three figures stood in the residents' car park outside my block of flats, perfectly still beneath a street lamp. Their proportions were wrong. They were too tall, their arms hung too low, and their heads did not sit properly on their necks.

I blinked.

They were closer.

They had crossed six metres without moving.

I remained inside the car with the engine running, watching them as they watched me. Other residents passed within metres of them without reacting. A dog began barking wildly and tried to drag its owner away, but the man merely tightened the lead and continued towards the building.

Only the dog and I could see them.

They remained for three hours. They did not move in any ordinary sense, but every time I blinked they were nearer.

As dawn approached, they ceased to be there.

They did not walk away or fade. One moment they occupied the car park. The next, the spaces beneath the street lamp were empty.

I went upstairs and packed everything I still owned into two bags. I took the laptop containing my research, the few clothes that fitted my changing body, Private Alastair James McRae's corroded identity disc and the journal in which I had reconstructed the Carta innkeeper's account from memory alongside everything I remembered of the purple world.

The gathering was five days away. I would spend the intervening time moving, sleeping in different places and making myself more difficult to follow. Then I would return north, meet the others and compare what we knew.

Perhaps we would find answers.

Perhaps we would merely lose our minds together, a collection of damaged soldiers and civilians trying to comprehend a universe that regarded humanity as another crop.

Either way, I had finished pretending to be normal. I was finished lying to therapists, flinching at red lights and waiting for those things to enter my room at night.

If Earth was merely another field in an infinite harvest, perhaps it was time for us to become something other than grain awaiting the blade. We could be weeds: difficult to kill, impossible to remove completely, spreading the truth wherever it might take root.

Five days later, I left Manchester and drove north again. The M6 carried me towards Scotland, and the A9 drew me deeper into the Highlands, towards the gathering and whatever answers thirty-nine survivors might possess.

In the rear-view mirror, my reflection changed whenever the road curved. Sometimes my hair was white and my nails were black. Sometimes my face was stretched and hollow. Once, something with too many joints appeared to be sitting behind me.

When I looked round, the back seat was empty.

The watchers followed in the glass, in the roadside shadows and between the dark ranks of trees. I knew they would always follow now.

But I was no longer running from them. I was travelling towards something: towards others who knew the sky could turn purple, who had seen their friends dissolve into light and who carried the mark of dimensions no human being was meant to survive.

Towards the damaged and displaced.

Towards those who had looked upon the beings cultivating our world and lived to remember them.
