The Faces Beneath the Rig

The helicopter had barely touched down before I was calculating deployment times in my head. About 45 miles west of Shetland, within the UK Continental Shelf, platform Kestrel Nine rose from the North Atlantic like a steel city, all pipes and cranes against the grey morning sky. The salt air felt different out there. Thicker, almost metallic.

I grabbed my kit bag and headed for the dive operations centre, trying to shake off the dream I'd had on the flight. I had been drowning again in the flooded River Ouse during the autumn 2000 floods. Only this time, the water had eyes.

Siobhan Kelleher met me at the door with a clipboard in her hand, her Irish accent cutting through the industrial noise.

"Bethan Price? Thank Christ you're here. We've been running with a skeleton crew for three days."

Her handshake was firm, but her fingers trembled slightly. Strands of red hair had escaped her ponytail, and behind her wire-framed glasses her green eyes darted between me and her paperwork, as though she were checking two different lists at once.

"Happy to help," I said, following her inside.

The operations centre smelt of tea, machine oil and the particular sort of stress sweat produced by too many sixteen-hour shifts.

"Right," Siobhan said as we walked. Her accent strengthened when she was tense. "Pipeline section Kilo Four needs immediate attention. There is corrosion at the joints and possible structural compromise. You'll be based in the subsea habitat for five days, with excursions in atmospheric suits. Lucy Harcourt was meant to work the rota with you. She's already here, sorting her kit."

We entered the briefing room, where three people were waiting. The blonde woman in the corner had to be Lucy. She was small, perhaps 157 centimetres tall, and was drawing in a notebook with quick, sharp strokes. She glanced up when we entered. Her pale blue eyes held mine for a second too long before dropping back to the page. Dark circles beneath them made her look as though she had not slept for days.

"That's Gareth Rowlands, equipment specialist," Siobhan continued, indicating a stocky man in a navy boiler suit who was fiddling with a depth gauge.

He looked up and grinned.

"Welcome to paradise," Gareth said. "Where the water's black, the pressure's crushing and the tea tastes faintly of hydraulic oil. Speaking of which..."

He held up the gauge.

"Third one this week giving impossible readings. Says we're already at negative depth, which would mean we're airborne."

Nobody laughed. Siobhan's jaw tightened.

"Replace it," she said, then turned to the woman in the lab coat. "Dr Asha Campbell, marine biologist. She'll be documenting the dive for the environmental monitoring required under the installation's UK offshore consent conditions."

Asha stood and shook my hand. She was about my height, with natural locks pulled back from her face and amber eyes that seemed to catalogue everything about me in seconds.

"Good to meet you. I've read about your North Sea subsea containment and environmental recovery work. Impressive."

"I was doing my job," I said.

Something in her tone made me wonder what else she had read.

Siobhan brought up the schematics on the wall monitor.

"Standard procedure. The one-atmosphere habitat is at about 600 metres. You'll transfer through the suit docking chamber, run rotating maintenance excursions and remain based below for the five-day deployment. Gareth will monitor your systems from up here. I'll coordinate the operation."

"I can't."

Lucy's voice was barely above a whisper, but it cut through Siobhan's words like a knife. We all turned. Her pencil was still moving, scoring violent lines across the page.

Siobhan's professional mask slipped for a moment, revealing something between frustration and fear.

"Lucy, we've discussed this. You've been cleared for the deployment."

"The company occupational psychologist hasn't been down there."

Lucy's pencil snapped. She stared at the broken pieces in her hand as though surprised by them.

"Sorry. I'm sorry. I'll go. Of course I'll go."

The room fell silent except for the hum of electronics and the distant clang of metal against metal outside. Gareth cleared his throat and made a joke about the tea urn being more dangerous than any deep-sea creature, but his timing was wrong and the joke landed flat.

Siobhan resumed the briefing. I kept looking at Lucy. She had begun drawing with the broken pencil stub. From where I sat, it looked as though she was sketching eyes. Dozens of them, overlapping and staring.

After twenty minutes of technical detail, Asha caught me beside the equipment lockers.

"Can I ask you something?"

She did not wait for an answer.

"In your experience, have you encountered visual or auditory anomalies at extreme depth? Specifically, shared hallucinations among dive teams?"

The question was so precise that my skin prickled.

"That's an odd thing to ask."

"It's for my research," she said quickly, though her gaze flicked towards the door as if she were checking whether anyone was listening. "Isolation and unusual sensory conditions can affect the brain. I'm studying the neurological effects."

"I've never had any problems," I lied.

There was no need to mention the dive at 550 metres when I could have sworn I heard my late grandfather calling my name, or the shadows that moved incorrectly at the edge of my vision during night work.

"Right. Of course." Asha adjusted her glasses. "Just academic curiosity."

Siobhan's voice carried from the corridor.

"Final equipment checks in five minutes."

I prepared methodically, checking every seal and gauge twice. The atmospheric diving suit weighed roughly 140 kilograms on deck, but its rigid pressure shell would keep me at one atmosphere throughout the excursion. There would be no saturation decompression obligation, although a failed recovery at that depth could still kill me in half a dozen other ways.

Gareth ran diagnostics, muttering about false readings and interference patterns. Through the window, I watched the waters west of Shetland shift from blue to grey as cloud rolled in.

"Weather closing in," he said, following my gaze. "Should pass north of us, but you never know out here. The Met Office has been wrong before."

Lucy appeared beside us, dressed for transfer apart from her helmet. Up close, I could see her hands trembling.

"They don't like the storms," she said quietly.

"Who doesn't?"

She blinked, seeming to return from somewhere far away.

"The fish. Deep-water fish. They go deeper when storms come."

Gareth and I exchanged a glance. He shrugged and returned to the diagnostics, but I filed the remark away.

Everything about the job felt wrong: Siobhan's nervous energy, Asha's questions, the impossible gauges and whatever was happening to Lucy.

The installation lights came on as evening approached, although it was barely 16:00. The clouds had turned the sky the colour of old steel, and the first drops of rain struck the windows. In two hours, Lucy and I would be descending through darkness while the storm passed overhead.

I touched the worn silver St Christopher medal at my throat, a habit before difficult dives. Whatever waited below, I had faced worse.

At least, that was what I told myself as the North Atlantic turned black beneath the platform lights.

The diving bell descended like a steel coffin on a cable. I checked my instruments for the third time.

Two hundred and forty metres, and descending.

Lucy sat opposite me with her knees drawn towards her chest, staring through the porthole at nothing. Only black water pressed against the glass.

"Are you all right?" I asked, though the answer was obvious.

Her breathing was shallow and fast. Condensation formed on the glass near her face.

"There."

She pressed a finger to the porthole.

"Right there. Do you see it?"

I leaned forwards, following the line of her finger. There was nothing beyond the light, which the void swallowed after a few metres.

"Lucy, there's nothing there."

"It's moving with us." Her voice rose. "Keeping pace."

Siobhan's voice crackled over the communications system.

"Lucy, focus on your breathing. In through your nose, hold for four, then out through your mouth. This is just as we practised in the pool."

The rehearsed calm did not quite conceal the strain beneath it.

"The pool didn't have them in it," Lucy muttered, but she began the breathing exercise.

Gareth joined the channel from the equipment room.

"Harcourt's heart rate is elevated, but all other readings are normal. Oxygen is good. Bell pressure is stable."

I watched Lucy count breaths on her fingers. This was not the first time Siobhan had talked her through an episode. The company had sent someone with a history of panic attacks on a five-day subsea deployment. Either they were desperate or stupid.

Perhaps both.

At 365 metres, Lucy's breathing exercise stopped working. She rocked in her seat, eyes unfocused.

"Lucy?"

I reached across the cramped bell and touched her shoulder. She jerked away.

"The pressure makes them visible. That's why nobody sees them at the surface. But down here, where the water gets heavy, they can't hide any more."

"Who can't hide?"

I kept my voice level, though something cold was crawling up my spine.

"Lucy, your heart rate is approaching dangerous levels," Siobhan said. "We need to consider-"

"No!"

Lucy's shout made me flinch.

"I have to go down. They said I have to go down. That's the only way to-"

She stopped mid-sentence and blinked rapidly, like someone waking from a dream.

"Sorry. I'm sorry. I don't know why I said that."

At 455 metres she began speaking again, but the words came out wrong. It was not gibberish, not quite. It sounded like an attempt to speak English using the wrong set of sounds. Her lips moved too quickly, and her tongue clicked against her teeth in patterns unlike any language I knew.

"Siobhan, something's wrong," I said. "This isn't only panic."

"It can't be a gas effect in a pressurised bell," Siobhan replied, but I heard papers being moved at her end. "Gareth, verify the atmosphere readings."

"Already have. Three times. Everything is normal up here, but I've seen plenty of diving-related neurological incidents. This isn't one of them."

Lucy's strange speech grew faster and more urgent. She gestured towards the porthole, then at me and the bell walls, as though she were trying to explain something vital but could not find the words.

Or any words that belonged to a human language.

"We're aborting her deployment," Siobhan said. "Bethan, secure her for recovery. The bell is returning to the installation. We'll lower your atmospheric suit in its deployment cage and continue you to the habitat separately."

I reached for Lucy's harness. She seized my arm with surprising strength, her fingers digging hard enough to hurt.

"They're already watching us."

The words were perfectly clear. Her eyes focused on mine, completely lucid. There was no panic or confusion in them. Only certainty.

"Who's watching us, Lucy?"

She blinked. The clarity vanished, her grip loosened and she slumped back.

"What? I don't... Did I say something?"

The bell began its ascent. Lucy pressed herself to the porthole as the remotely deployed suit cage came into view below us. I transferred into the atmospheric suit through the bell's lock and secured myself inside the cage while the recovery crew took Lucy upwards.

In the brief moment when our lights crossed, I saw what looked like her reflection in the bell glass.

The angle was wrong for a reflection.

And the face looking back had too many teeth.

I shook my head and checked the suit atmosphere. Every reading was normal, but Lucy's words remained with me as the cage continued down alone.

They're already watching us.

It was the sort of thing people said when they were losing their grip. The sort of thing that sounded absurd until you were 550 metres beneath the North Atlantic and wondering whether the shadow at the edge of your lights had moved by itself.

Siobhan's voice reached me through the helmet communications, calm, professional and tired.

"Bethan, you're approaching the habitat. You should have visual contact in about three minutes."

"Received."

I adjusted the cage controls, trying to ignore how empty the descent felt without Lucy's frightened breathing.

"Siobhan, has Lucy had episodes like that before?"

The pause was too long to be casual.

"She was medically cleared. That's all I'm authorised to discuss."

Which meant yes, she had experienced something before. Siobhan had known, and they had sent her down anyway.

I thought of Gareth's impossible depth gauge, Asha's questions about shared hallucinations and the tremor in Siobhan's hand when she greeted me.

The habitat lights appeared below, a tiny island of aluminium and artificial light in a black ocean. As I descended towards it, I checked the water beyond the cage more often than necessary, searching for movement and watchers, finding only darkness looking back.

At about 600 metres, the deployment cage locked against the habitat's suit docking chamber. I cycled the seals, disconnected from the rigid suit and pulled myself into the pressure-rated, one-atmosphere compartment.

The structure groaned beneath the load of the sea, as if it were digesting something.

The main compartment was smaller than my bathroom at home: two bunks, a tiny galley and equipment storage packed into a space intended to house two people for five days. Now it would house one.

"Bethan, confirm you're secure in the habitat."

Siobhan sounded thin and distant, as if she were calling from another planet.

"I'm in. Systems appear sound."

I ran the checks. Oxygen, CO2 scrubbers, internal pressure, docking seals. All normal. Whatever had happened to Lucy, the habitat was not responsible.

"Received. Lucy is being treated in the medical bay. The offshore medic is consulting the onshore diving medical team. They think severe anxiety or an acute neurological event, although..."

Siobhan trailed off.

"Although what?"

"Her symptoms don't match anything they recognise. Her blood pressure is fluctuating, her pupils are dilated and she keeps talking about-"

The transmission broke into static. Gareth replaced her.

"Bethan, we're having trouble up here. The backup communications array has gone offline, and both the diving bell recovery winch and the secondary lift system are producing error codes I've never seen before."

Wonderful. Six hundred metres underwater with the recovery systems failing.

I secured the atmospheric suit in the docking chamber and changed into a dry boiler suit. The habitat's recycled air tasted metallic, like breathing through a mouthful of pennies.

"How many systems are affected?"

"Four so far. Possibly five. It's as if they're communicating with one another and deciding to fail in sequence. I've seen equipment faults, but never anything coordinated like this."

He sounded puzzled rather than frightened, which frightened me more.

I opened the supply lockers in search of the repair schedule. The third locker stuck. Something had been wedged behind it against the hull. I reached into the gap and felt leather.

It was a small journal, taped to the wall as if someone had hidden it. The cover was water-stained but intact. Several different hands filled its pages.

The first entry was dated three months earlier.

Day three. They are not hallucinations. Pawel Nowak saw them too. Massive shapes that should not exist at this depth. We agreed not to report them. Who would believe us?

Another hand had written an entry two weeks later.

The pressure isn't causing this. I've completed fifty deep-water excursions and never felt watched like this. They are studying us. Learning our routines.

I turned the pages. There were dozens of entries from different divers, all describing the same things: enormous forms in the darkness, the sensation of being observed and equipment failures that made no sense.

"Bethan, respond to radio check."

Siobhan's voice made me jump.

"I'm here. I've been responding."

"Negative. We've had silence for three minutes. Are you disorientated?"

Three minutes? I had been reading for perhaps thirty seconds.

"Siobhan, I've found something. A journal. Previous dive teams have been documenting-"

"There is no journal in the habitat inventory."

She interrupted too quickly. The answer sounded rehearsed.

"Bethan, sensory deprivation can produce extremely vivid experiences."

"I'm holding it in my hands."

"I need you to-"

Gareth cut across her.

"Stop lying to her, Siobhan."

There was a pause. When he spoke again, his voice was quieter.

"Bethan, I've found similar journals on three other installations. Company orders were to destroy them, but I kept copies. Whatever you're reading is real."

The channel remained silent for several seconds.

When Siobhan replied, stress had thickened her Irish accent.

"Gareth, you're breaching your company confidentiality agreement."

"To hell with the agreement. She needs to know what-"

Asha burst onto the channel, breathing hard as though she had been running.

"Siobhan, we have a situation. Lucy has locked herself in the medical bay. She's... God, she's drawing on the walls with blood. Her own blood."

My stomach dropped.

"Drawing what?"

"Eyes. Hundreds of enormous eyes. They're all looking in the same direction. Down."

I stared at the journal, then at the porthole. Nothing showed beyond it but black water.

One of the final entries caught my attention, written in a shaking hand.

They are getting closer. Each team sees them nearer the habitat. Perhaps they are building up courage. Perhaps they are waiting for something.

"Asha, those organisms you sampled - could they cause hallucinations?"

"I don't know yet. Possibly. But Lucy isn't in the water now. She should not still be affected unless..."

She stopped.

"Unless what?"

"Unless the exposure has persisted. The organisms may remain active on her nervous system or in her bloodstream."

The habitat lights flickered for a second, long enough to remind me how complete the darkness outside was.

I moved to the porthole and pressed my face to the cold glass. The work lights illuminated perhaps three metres of murky water.

They flickered again.

In the moment of darkness, I saw a shape just beyond their reach. It was massive and impossible.

When the power steadied, it had gone.

"Siobhan," I said, keeping my voice level. "How many dive teams have reported unusual experiences here?"

Silence.

"Siobhan."

"The earliest concealed reports began two years ago," she admitted. "During the past six months, every team sent to a known contact site has reported something. But the company said-"

"The company knew," Gareth said bitterly. "They've known all along, and they kept sending people down."

I sat on the narrow bunk with the journal in my hands.

Five days down here. Alone. With something watching from the darkness.

The last entry was dated one week earlier.

I think they are trying to communicate. The equipment failures follow patterns, and so do their movements. It is not random. They are intelligent, and they are desperate. The drilling is hurting them. We are hurting them, and they do not know how else to make us stop.

"Bethan." Siobhan sounded small and frightened. "Your first excursion starts in twenty minutes. Pipeline section Kilo Four still needs those repairs."

I looked at the atmospheric suit in its docking chamber, then back at the porthole.

"Yes. I'll be ready."

Ready for what? To go outside and pretend nothing was wrong? To ignore whatever was circling the habitat and drawing nearer with every deployment?

The lights flickered once more.

This time, I did not look outside.

Some things were easier to face when you could not see them coming.

The welding torch cast sparks into the water, where the darkness swallowed them at once. I had been working for twenty minutes, moving along the corroded joints of pipeline section Kilo Four and trying not to think about how alone I was.

The habitat stood about 40 metres behind me. Its lights were barely visible through the murk. It might as well have been 40 miles away.

"How is the repair progressing?" Siobhan asked through the helmet communications, her voice tight with exhaustion.

"Joint three of twelve. The corrosion is worse than the scans suggested. This entire section should have been replaced months ago."

I adjusted the torch and watched the metal bubble and fuse.

"Patch what you can. We need it functional, not pretty."

There were muffled voices behind her, followed by shouting and a door slamming. Siobhan muttered something that was certainly not a blessing.

"Everything all right up there?"

"Lucy is awake. She's..."

A pause.

"Gareth, tell me you're recording this."

"I am," he said. "But no one is going to believe it. She's covered every surface in the medical bay with eyes. Walls, ceiling, floor, even the inside of the door. Hundreds of them, all different sizes, all looking towards the same point. Down and south-west."

I checked my compass. South-west was precisely where I was working.

"She did that while unconscious?"

"Not unconscious. Catatonic. Eyes open, no response, but her hands kept moving. Like automatic writing, except she was drawing."

Gareth sounded genuinely unsettled, which was difficult to achieve.

"The offshore medic says her brain activity is extraordinarily high, but she isn't responding to stimuli."

I concentrated on the weld and tried to ignore the prickling at the back of my neck. It was the feeling of someone standing behind you in an empty room, except I was surrounded by 600 metres of water.

The suit's rear camera showed nothing but black.

"Asha is analysing the water samples," Siobhan said, plainly trying to change the subject. "She's looking for toxins, bacteria or anything else that might account for these experiences."

"They are not hallucinations if several people see the same thing."

"Shared suggestion and mass psychogenic responses are well documented in isolated environments."

Right. Shared suggestion that made machinery fail in sequence and caused a catatonic woman to draw the same images as people hundreds of metres below her.

The fourth joint was almost completely severed. I ran one gloved finger along the break. Its edges were smooth rather than jagged, as if something had dissolved the metal from inside.

"Gareth, are you receiving my camera feed?"

"Yes. That isn't ordinary corrosion. Metal doesn't fail like that unless..."

He stopped.

"That's odd."

"What is?"

"Your external camera glitched for half a second. It looked like an interference pattern, but there's nothing near you that should produce one."

I turned slowly and swept my lights through the darkness. There was nothing there. Only empty water and drifting particles that resembled snow falling upwards. The pipeline vanished into blackness after six metres in either direction.

"Bethan, your heart rate is rising," Siobhan said. "Do you need a pause?"

"I'm fine."

I was not. The sensation of being watched had intensified, as if the watcher had moved closer. My lights seemed weaker, though the power readings were normal.

"I need to finish this section."

I forced myself back to the weld, but my hands were less steady. The torch sputtered once, then again. In the brief darkness between flashes, I saw something pale at the edge of my vision.

When the light steadied, there was nothing.

"Asha wants to know whether you've noticed any bioluminescence," Siobhan said. "She's found unusual microscopic organisms in the samples. They glow under certain conditions."

"Nothing glowing. Only darkness."

I moved to the fifth joint. It was bent at an unnatural angle, as if something beneath it had pushed upwards.

"How is Lucy?"

"Unchanged, although..." Siobhan hesitated. "Just before she became catatonic, she said, 'They've been trying to warn us.' When the medic asked who she meant, she pointed down."

The torchlight reflected from something in the distance. I turned my helmet lamp towards it, but the beam vanished into the void. Whatever had caught the light was gone, or had moved beyond my range.

"There's something out here," I said, surprised by how calm I sounded.

"Probably fish. Deep-water species can grow quite large."

"Fish don't cast shadows that size."

Silence followed.

Then Gareth asked, "How large?"

I looked upwards, trying to measure something I had sensed more than seen. The darkness above seemed heavier and more substantial.

"Large enough to block the little light reaching this depth. Like a building hanging over me."

"A whale, perhaps," Siobhan began.

"Whales don't hover. And they don't remain perfectly still for three minutes."

More silence. I heard Asha speaking urgently in the background, too far from Siobhan's microphone for me to distinguish the words.

"Asha says the organisms respond to electromagnetic fields," Siobhan told me. "Fields like those produced by your equipment. They may be attracted to your lights and torch."

"Attracted or disturbed?"

"She doesn't know."

I completed the fifth joint and moved to the sixth. It was intact but coated in something resembling organic growth. Fine filaments waved in water where there was no current.

I reached out to brush them away. They recoiled from my glove and curled back like tiny fingers.

"That's new."

I activated the macro setting on my helmet camera.

"Can you see this?"

"We're recording it," Gareth said. "Asha will want a sample."

Every light went out.

Not only my suit lamps, but the habitat lights behind me, the emergency markers along the pipeline and even the faint glow of the helmet display.

The darkness was absolute. I had never experienced anything like it, not even in cave dives. It was the kind of darkness that made you question whether your eyes were open.

Then everything returned at once.

"Bethan, respond!" Siobhan's voice burst through the restored communications.

"I'm here. What happened?"

"A power disturbance across the installation. It knocked everything out for about ten seconds."

Ten seconds. It had felt like less than one.

"My chronometer records a one-second interruption."

"Mine recorded thirty," Gareth said grimly. "Siobhan's recorded ten. And Lucy has just sat upright and said, 'They're trying to talk, but we're not listening.'"

I looked at the sixth joint. The filaments had disappeared without a trace.

Where they had been, a pattern had been etched into the metal. The marks were not corrosion or random damage. They formed a deliberate spiral of repeated symbols, each about the size of my thumb.

"I'm returning to the habitat."

"Negative," Siobhan said, although there was no conviction in it. "You have three hours remaining on this excursion."

"Something is down here with me. Something large enough to cause power failures and leave messages on our equipment."

"We don't know that-"

"Then what is it?"

I engaged the suit's thrusters and followed the pipeline towards the habitat. Its lights looked impossibly distant.

"From where I am, something is trying to communicate, and we're too stupid or too frightened to listen."

A shadow passed over me again, closer this time. I felt its mass displace the water, producing currents that should not have existed at that depth.

My lights dimmed. They were not failing. Their beams were being absorbed by something so vast that the illumination simply vanished against it.

"Bethan, your camera is showing... Jesus Christ." Gareth's voice cracked. "There's something behind you. I can't tell what I'm looking at. It's too large for the frame."

I did not turn. Some primitive part of my brain knew that if I saw it clearly, I would never be able to unsee it.

I kept the thrusters steady and moved towards the habitat while something immense shifted in the darkness behind me.

"It isn't immediately hostile," I said. I did not know why I believed it, only that I felt certain. "If it wanted to kill me, I'd already be dead. It's been avoiding direct contact, and it hasn't touched the habitat."

"Then what does it want?" Siobhan asked.

The habitat was thirty metres away. Then twenty. Ten.

When I reached the docking chamber, I finally turned towards the pipeline.

There was nothing there but darkness and the dying glow of the torch I had left behind. Yet the darkness possessed weight now. Presence. Somewhere within it, attention focused on me so intensely that my teeth ached.

"I think it wants us to know it's here," I said as the suit locked into the habitat. "Not merely see it on sonar or glimpse it in the dark. It wants us to understand what we're doing."

"Doing what?"

I thought of the smooth breaks in the pipeline, the filaments recoiling from my glove and the pattern cut into the metal like a written language.

"Trespassing," I said. "We're trespassing in someone's home."

The habitat air still tasted of pennies, with the added tang of my own fear. Gareth and Asha reviewed the recordings while I replaced the torch feed and inspected the suit. The footage showed interference, darkness and fragments of something too large for the camera to resolve. It showed enough to prove that I had not imagined everything, but not enough to identify what had followed me.

Asha requested another water sample from the growth around joint six. Siobhan argued that the repair could not remain incomplete. After an hour in the habitat, I went back outside.

I worked on joint seven, trying to convince myself that the earlier shape had been a trick of light and particulate matter. The torch flame danced across the corroded metal, each spark dying in the black water like a tiny failed star.

"Bethan, listen to this."

Asha's voice came through my helmet communications, high with excitement. Not the pleasant sort. It was the excitement scientists felt when they discovered something capable of rewriting textbooks or ending careers.

"I'm a little occupied."

I altered the torch angle and watched the metal seal. The joint was worse than the others, eaten through in a pattern like lace.

"The water samples are extraordinary. The organisms don't appear in any database and have no close known relatives. They're bioluminescent, but that isn't the strange part."

I paused mid-weld. If bioluminescence was not the strange part, we were in trouble.

"What is?"

"They respond to electromagnetic fields, particularly the weak fields associated with human neural activity. I placed a sealed sample near an EEG unit in the medical bay. The organisms illuminated in distinct patterns corresponding to different brainwave frequencies. It looked like the Blackpool Illuminations in miniature."

The torch sputtered. Its fuel indicator still showed half full.

"You're saying they react to thoughts?"

"To the electrical signatures associated with thought. More importantly, they appear to amplify those signatures, almost like biological signal relays. If enough of them surrounded a person-"

Siobhan interrupted.

"Could they cause hallucinations or neurological symptoms?"

"I don't know yet. Possibly. The brain works through electrical and chemical signals. If these organisms can amplify, transmit or interfere with them..."

Asha let the sentence trail off, but we all understood where it led.

"They may still be active in Lucy," I said.

"Yes. Preliminary microscopy suggests some entered through tiny cuts in her skin and may have persisted in her blood. Others could be adhering to nerve tissue. We need proper imaging and genetic sequencing before I can be certain."

I moved to joint eight. It bore the same smooth breaks, as though dissolved from within.

"How long have these things existed?"

"I can't date them directly from a fresh sample. Their cellular structure is highly streamlined, apparently adapted to one specialised function. I've compared the images with archived samples collected from other northern North Atlantic sites, and there are suggestive matches in material classified as contamination. Preliminary genetic evidence may indicate a very ancient lineage, possibly millions of years old, but that conclusion is provisional."

Gareth joined the channel.

"Speaking of strange, Lucy is awake and drawing again."

My hand slipped on the torch control.

"More eyes?"

"People this time. Or something roughly humanoid. They're too tall, and the features are soft and indistinct. Every one of them is crying."

I remembered the immense shadow above me and the pressure of its attention.

"How many?"

"Fourteen so far. Different sizes and positions, but all with tears running down their faces. She's marked them like locations. Asha thinks they may correspond to the fourteen proposed drilling sites scheduled across the following nine months. The offshore medic says Lucy's motor control is perfect. There's no sign of the earlier catatonia. She's lucid, but she will not stop drawing."

My wrist depth display began to fluctuate.

Six hundred metres. Five hundred and eighty-five. Five hundred and fifty. Four hundred and fifty-five.

The values leapt through impossible changes that would have meant catastrophic movement if they were real.

"Gareth, my depth readings are unstable."

"Everything is steady here. You're at 600 metres. It must be a gauge fault."

It did not feel like one. Every change was accompanied by a subtle alteration in the water against the suit, as if invisible currents were pushing and pulling at me.

I directed my helmet lights into deeper water, beyond the point where the pipeline disappeared into blackness.

For a second, I saw features there: the curve of a cheek, the hollow of an eye socket, the bridge of a nose. They were vast and indistinct but undeniably face-like. When I looked directly at them, they dissolved like smoke.

"There's something below me."

"Fish," Siobhan said automatically, though she no longer sounded convinced.

"Fish with human faces."

No one spoke.

Then Siobhan said quietly, "Lucy has just said they've been waiting for someone like Bethan."

My blood chilled.

"What does that mean?"

"I don't know. She's coherent now. Completely coherent. She says the previous teams saw them as well."

I stopped welding.

"That isn't what the reports say."

"No," Siobhan replied, and I heard papers moving. "The official reports record no unusual incidents. But Lucy says she spoke to divers from other installations. They all saw faces in the water. They all felt watched. They were threatened with the loss of redundancy terms, pension rights and future offshore certification if they spoke."

"I can confirm it," Gareth said. "I have recordings and witness statements. The company has concealed incidents across its northern North Atlantic operation and beyond. There are reports associated with 47 active or monitored installations across the UK Continental Shelf. The earliest are two years old, but contact has become consistent and more intense during the last six months."

"Forty-three recorded encounters in that six-month period," Siobhan said. "All classified as equipment faults or pressure-related sensory disturbances."

The torchlight caught something below. This time I did not look straight at it. I allowed my peripheral vision to hold the shape.

It was a face, or the visible portion of one. It was perhaps fifteen metres across, but its edges merged into a body far larger than the light could reveal. Its features looked soft, like wax exposed to heat.

It was looking up at me.

The suit's external microphones detected a sound. At first I thought it was whale song, the low mournful call that travels for miles underwater. But this was too regular and rhythmic.

It sounded like sobbing.

"Can you hear that?"

"Hear what?" Gareth asked.

"Crying. Something is crying down here."

The sound grew louder, or perhaps nearer. It was not a single voice but several, joined in grief.

My depth display spun through meaningless values. Two hundred metres. Nine hundred. Thirty.

"Asha, could the organisms transmit sound, or the perception of it?"

"Theoretically. If they respond to neural activity, they might stimulate the auditory cortex and make you hear something that isn't physically present. Or they may translate frequencies outside normal human hearing."

"A biological translator."

"Possibly. More like a communications network."

The sobbing intensified. My chest tightened beneath an emotion that did not belong to me. The grief was so profound that my eyes watered inside the helmet.

The face below had not moved, yet I knew it was the source. It was crying, and through the microscopic organisms in the water I was feeling its sorrow.

"I need to go deeper," I heard myself say.

"Absolutely not," Siobhan snapped. "Return to the habitat immediately."

I had already engaged the suit's downward thrusters, leaving the pipeline behind. The face clarified as I descended.

It was not human, only human-like. Its eyes were closed, its mouth slightly open. Its features suggested immense age and exhaustion.

"Bethan, this is a direct order. Return to the habitat now. A rapid uncontrolled recovery could damage the suit, sever communications or leave the bell unable to capture you."

"It isn't attacking. It's grieving."

"You don't know what it is."

I descended another three metres, then six. The visible face filled my entire field of vision, while the rest of the being extended beyond the reach of my lamps like a submerged cathedral.

The sobbing ceased to be merely a sound. It became vibration, passing through the suit and into my bones.

"Lucy's drawing again," Gareth said. "Christ. She's drawing precisely what your camera shows. The face, your position, everything."

"How can she see it?"

Asha answered before anyone else could.

"The organisms. If they remain active in Lucy and are surrounding Bethan, they may be carrying the same neural pattern between them. They're forming a biological network."

The being's eyes began to open, slowly, like those of someone waking from a dream that had lasted for centuries.

Its pupils were enormous and as dark as the water surrounding them. There was intelligence in that gaze. Ancient and alien, but unmistakably aware.

"It sees me," I whispered.

In that moment, looking into those impossible eyes, I understood why they were crying.

Images flooded my mind. They were not my memories, but theirs: drilling, destruction, the slow poisoning of their deepest places. We were not merely trespassing. We were destroying their world, and they did not know how to make us stop.

"They're trying to talk to us," I said. "They've been trying for months, and we've called it hallucination."

The vast mouth moved, shaping words in no language I knew, yet I felt their meaning through the organisms in the water, through the biological network Dr Asha Campbell had discovered. One word came again and again.

Please.

The sobbing ceased. Somehow, the silence was worse.

I hung beside joint eight of pipeline section Kilo Four, my torch dead in my hand, listening to my breathing and the distant hum of the habitat's life-support system. The terrible sound had reverberated through the water for thirty minutes. Now it had stopped as abruptly as if someone had thrown a switch.

"Bethan, your heart rate has been elevated for twenty minutes," Siobhan Kelleher said through the communications link. "I need you to return to the habitat for evaluation."

"Something's below me." I angled the atmospheric suit away from the pipeline and engaged the downward thrusters. "Whatever made that sound is still there. I can feel it."

"Feel what? There is nothing on sonar."

"Sonar doesn't detect everything."

I descended another three metres. My lamps cut through water so black it seemed to swallow their beams.

"Sometimes you have to get close enough to see."

Stress thickened the rhythm of Siobhan's Irish accent. "That is precisely the sort of thinking that causes diving accidents. You may be experiencing pressure-induced paranoia."

"Then explain why I feel as though something the size of a building is watching me."

I was fifteen metres below the pipeline now, descending through water that felt heavier and more substantial than seawater, almost like liquid metal. My depth gauge passed 615 metres, but the pressure readings fluctuated as though I were far deeper.

"Bethan, please." Siobhan's voice cracked. "I am ordering you to return to the habitat immediately."

"In a minute."

I kept descending, following an instinct I could not name. The darkness ahead seemed to possess texture and weight.

"I just need to see."

My lamps found something pale. At first I mistook it for the seabed, some immense rock formation rising from the abyssal plain. Then I saw that the surface was too smooth and organic. I adjusted my angle, sweeping the beams across what looked like skin.

Impossibly vast skin stretched over something whose edges my lights could not reach.

"Jesus Christ," I whispered.

"What? Bethan, what can you see?"

I moved closer, my heart pounding against my ribs. The pale surface curved away in every direction and vanished into the dark. Subtle ridges and hollows suggested structures beneath it. I followed one ridge upwards with my light.

An eye opened.

It was not human-sized or whale-sized. It was the size of a building. The pupil alone seemed larger than the habitat, as black as the surrounding water and somehow deeper. The iris was pale grey, threaded with silver veins that gave off their own pulsing light.

"Oh God."

The eye focused on me. It tracked my movement as I hung paralysed in the water. An intelligence looked back from that impossible gaze - ancient, alien and unmistakably aware.

"Bethan. Bethan, answer me."

Siobhan's voice broke through my paralysis.

"Your readings have spiked across the board. Heart rate, blood pressure, neural activity. What is happening down there?"

"There's a face," I said, astonished by the steadiness of my voice. "A human-like face, nearly a hundred metres across. One of its eyes has opened, and it's looking at me."

The channel fell silent. Then Gareth Rowlands spoke, disbelief tightening his voice.

"Say that again."

"An enormous face. It's watching me."

"That isn't possible," Siobhan said, but certainty had left her voice.

"Lucy has just sat upright," Gareth reported. "She's drawing again. Fast - as if her hand can scarcely keep up."

"What is she drawing?"

I already knew.

"A vast face with one eye open. She's adding details before you describe them."

Asha cut in, breathless with fear and excitement. "The organisms are not merely responding to neural activity. They are transmitting it. They appear to be creating a biological network between exposed individuals. If Lucy can see what Bethan sees -"

The second eye opened.

Both pupils fixed on me. In twelve years of deep-water work, I had never felt anything like what passed through me then. It was not fear. Fear would have been sane and familiar.

It was recognition, like meeting an old friend in an impossible place.

"It knows me," I said.

"Bethan, ascend immediately," Siobhan ordered. "Whatever you think you are seeing -"

"I'm not thinking it. I'm looking at it."

As my eyes adjusted, the face emerged more clearly. Its features were soft and indistinct, as if carved from fog, but unmistakable. Its mouth hung slightly open, as though it had been speaking when I arrived.

"That sobbing was communication. It has been trying to talk to us."

"Hallucinations can seem entirely real under pressure," Siobhan said, though she no longer sounded convinced.

"Then how is Lucy drawing exactly what I can see?"

No one answered.

I engaged the suit's thrusters and moved closer, drawn by something deeper than curiosity. The face showed neither hostility nor threat. That ancient intelligence studied me with the patience of something that had waited a very long time.

"Its mouth is moving," I said. "It's trying to speak."

"Bethan, get away from it. Now."

Real panic sharpened Siobhan's command, but I could not obey. The being's expression altered, its features settling into something almost hopeful. It was as though it had waited for someone to see it properly instead of dismissing it as equipment failure or pressure psychosis.

"It isn't hostile. It seems curious. Relieved, perhaps."

"You cannot know that."

From about thirty metres away, I could see that the irises were not solid grey. They consisted of thousands of tiny lights, like stars behind cloud. They pulsed in rhythmic, purposeful sequences.

"The lights in its eyes are signalling. It resembles coded naval signalling, but it is far more complex."

"Lucy is drawing the patterns," Gareth said grimly. "She has covered an entire wall with dots and lines arranged in repeating groups."

"Language," Asha breathed. "It may be trying to teach you its language."

The mouth opened wider. Vibrations passed through the water, not quite sound but something deeper, focused directly upon me.

"I can feel it talking. Not hear it - feel it in my bones and chest."

"Bethan, please," Siobhan said. "This is beyond our understanding. Return to safety."

Safety was meaningless. The being could have crushed me effortlessly. It could have destroyed the pressure-rated habitat, platform Kestrel Nine and everyone aboard. Instead, it was exercising extraordinary restraint while trying to make me understand.

The eyes closed in a slow blink that lasted several seconds. When they opened, hope remained in them, but grief lay beneath it - the same bottomless grief I had heard in the sobbing.

"It's crying," I said. "Not yet with tears, but it is grieving."

"Lucy has written something," Gareth said. "In English. She wrote, 'They're dying because of us.'"

The face turned, exposing part of its profile. Along the immense cheekbone were scars: straight lines and geometric wounds disturbingly like drilling patterns.

"There are marks on its face. Scars. They look like damage from drill heads."

Siobhan drew a sharp breath.

"How many active or monitored installations are there across the UK Continental Shelf?" I asked.

"Forty-seven connected to the reports," she said quietly.

"And how many have recorded unusual experiences?"

A pause.

"All of them."

The being turned back. Its gaze intensified, and the suit's pressure sensors fluctuated wildly. The truth was there in front of us. We had not merely drilled into its territory. We had drilled into bodies, homes and lives.

"They aren't hallucinations," I said. "They're alive, and we're killing them."

The enormous eyes held mine, and the darkness around me vanished.

I was eight years old again, thrashing in the flooded River Ouse during the autumn 2000 floods. Muddy water closed over my head. My lungs burned as I sank, seized by the certainty that I was going to die. Then my late grandfather's hand caught my coat and dragged me towards air.

The memory did not belong solely to me now. The being saw it too. Its expression shifted with recognition and understanding as the intelligence behind those colossal eyes read my memory like writing on a page.

"Bethan, your readings are spiking again," Siobhan said, distant and tinny through my helmet communications.

The mouth opened. Meaning flowed directly into me: water, drowning, and the terror of knowing that the substance sustaining all life could also take it away.

Beneath that terror lay compassion.

"It knows," I whispered, my fingers closing around the worn silver St Christopher medal beneath my suit's inner layer. "It knows about the drowning."

"Bethan, listen to me." Siobhan's voice carried guilt and exhaustion. "There is something I must tell you about why you are really down there. The company knows about these beings. The earliest concealed reports began two years ago, at platform Kestrel Nine. Encounters have become universal and much more intense over the past six months. Management classified them as equipment faults, pressure psychosis - anything except the truth."

Cold spread through me.

"You knew?"

"I have been documenting incidents across forty-seven active or monitored installations on the UK Continental Shelf. The company threatened my redundancy terms, my pension and my future offshore certification if I went to the authorities. But management wanted more information. They sent divers to known contact sites deliberately, to provoke encounters and study human reactions."

"You used me as bait."

The words came out flat, though anger burned through me.

"I'm sorry," Siobhan said. "God, Bethan, I'm so sorry."

"She isn't the only one with secrets," Gareth cut in. "I've recorded every conversation, incident report and order to keep quiet. I have testimony from divers throughout the company's northern North Atlantic operation. I prepared an evidence package before this deployment and arranged for it to be transmitted if communications failed."

The being's eyes tracked the exchange, their lights pulsing faster.

"How many divers?"

"Hundreds. All reporting enormous shapes, coordinated equipment failures and the feeling of being watched. All threatened into silence."

Asha returned to the channel. "I have compared the organisms from Lucy's samples with archived material quietly retained from previous incidents. Microscopy confirms that the structures are consistent across sites. Preliminary genetic work suggests deliberate organisation rather than a naturally evolved colony. The dating is provisional, but the archived mineral associations may place the lineage millions of years in the past."

"What are they?"

"Biological technology, perhaps. A communications network dispersed through the water, able to interface with nervous systems. The organisms remain active in Lucy's bloodstream or on her nervous tissue even after removal from the sea. That is why she can still see through you."

The being began to weep.

Tears the size of a small fishing boat streamed from its eyes and surged upwards. They did not fall at this depth; they rose with tremendous force, generating currents that struck the atmospheric suit like an express train.

"Jesus! Siobhan, I'm caught in a current."

"Engage downward thrusters and set the suit to maximum negative trim. Gareth, ready the diving bell recovery winch and secondary lift system."

I fired the thrusters. The upward flow seized the roughly 140-kilogram suit and spun me end over end. An uncontrolled ascent would not give me decompression sickness inside an atmospheric system, but it could overwhelm the joints, rupture a seal, rob me of control or carry me beyond the bell recovery envelope.

Each tear possessed enough force to crush the suit, yet each one curved aside. The currents battered me, but the vast bodies of water themselves parted deliberately around me.

"It isn't trying to hurt me," I gasped. "It's avoiding me."

Another grief-driven surge sent me tumbling. In the erratic sweep of my lamps I glimpsed a second face in the distance. It was smaller only by comparison, with more clearly defined human-like features. It watched the weeping elder with concern, perhaps even alarm.

"There's another one. A younger one, I think."

"How many are there?" Siobhan asked.

"I don't know. But they aren't solitary. They're a community - a civilisation."

The younger face turned towards me. Its gaze was sharper and more immediate than the ancient sorrow of the first. Its mouth moved, sending urgent vibrations through the water.

"Asha, could the organisms translate between different forms of consciousness? Human to whatever these beings are?"

"In theory. If they interface with neural activity, they might act as a biological translator between any thinking organisms."

Images struck me again: drilling installations collapsing, gigantic forms rising from the deep, and the ocean turning violently against intrusion. These were not threats alone. They were warnings of geological structures failing, seabeds rupturing and waves striking the coasts and island communities of northern Scotland.

Beneath every image was the same plea.

Please.

"They're warning us," I said. "The failures, visions and tears are attempts to stop the drilling before something catastrophic happens. They can disable our infrastructure, and if we force them to defend themselves - or destabilise the geology around them - the consequences will be beyond anything we can contain."

The currents weakened as the elder's tears slowed. Hope returned to those immense eyes, desperate and fragile.

"Siobhan, how much more drilling is planned?"

After a long pause, she said, "Fourteen proposed sites over the following nine months, all in deep water and previously unexplored territory."

The younger being looked relieved when I said, "We have to stop it. All of it, until we understand what we're damaging."

The elder's tears ceased. In the stillness, both beings watched me with an attention that made my bones ache. They were waiting to learn whether humanity would listen or whether they would need another way to protect their home.

I fought the last of the current until the thrusters arrested my ascent about fifteen metres above the one-atmosphere habitat. Then I descended towards its suit docking chamber.

"Siobhan," I said, "how long have you really known?"

"Two years. The first reports came from Kestrel Nine: huge shapes, failures and the sense of being watched. The company occupational psychologist labelled it pressure psychosis. Management wanted human responses studied under controlled conditions. I did not choose this, Bethan, but I cooperated, and that is on me."

"I've got enough to prove it," Gareth said. "Records from all forty-seven installations, including the deliberate deployments."

I locked into the docking chamber. Mechanical arms secured the suit, equalised the interface and opened the rear hatch into the habitat's one-atmosphere interior. Only then could I climb out without exposing the living compartment to the sea.

My hands shook as I pulled on a dry boiler suit.

"You weren't sent merely to repair Kilo Four," Gareth said. "You were sent to make contact."

"I've analysed Lucy's drawings," Asha said. "They are detailed topographical maps. She has marked fourteen locations so far - the proposed drilling zones, or perhaps the beings most endangered by them. Lines connect those sites like neural pathways."

The habitat lights flickered twice. In the brief darkness, shapes moved beyond the porthole: immense, coordinated forms at the edge of the external lamps.

"They're talking to one another," I said, pressing close to the glass. "Whatever this is, it is much larger than a few isolated beings."

Alarms began sounding over Gareth's equipment.

"I'm losing contact with Kestrel Nine. Both the primary and backup communications arrays are showing structured interference."

"From what?" Siobhan demanded.

"I don't know, but it is coordinated."

The habitat shuddered. Metal groaned under stresses its instruments could not explain. A third face emerged from deeper water, smaller and more sharply defined than the others, its features almost human despite their impossible scale.

"Another one is approaching."

"Bethan, step away from the porthole," Siobhan ordered.

I could not move. The third being's eyes held an intelligence that felt accessible, almost familiar. Recognition passed between us. Its mouth opened, and sound filled the water - not the elder's bone-deep resonance, but articulated speech with unmistakable cadence and structure.

"It's talking. Using words."

The pressure hull became a resonating chamber. Alien phrases echoed through the cramped habitat, and I strained towards a meaning that seemed always just beyond reach.

"Asha, do the organisms pulse in patterns?"

"Yes, but how did you -" She stopped. "Oh my God. The frequencies match. Its vocalisations are triggering corresponding patterns in the organisms."

The face moved nearer until only one eye fitted within the porthole. Its next utterance seemed to bypass my ears and vibrate directly in my chest. I understood fragments of emotion: urgency, desperation, a plea to be understood.

"Bethan," Siobhan said through worsening interference, "Kestrel Nine is suffering cascading failures. Navigation, communications and backup life support are shutting down in sequence. A coordinated offshore response involving HM Coastguard and the platform's standby vessel is being arranged, but the interference is delaying it."

"It isn't an ordinary failure," Gareth said. "Other installations are reporting simultaneous shutdowns wherever encounters have occurred. All forty-seven associated sites have recorded malfunctions within the past six hours."

The eye followed me as I paced the tiny compartment. Its ancient patience was running out.

"My contacts extend beyond the UK Continental Shelf," Gareth continued. "There are whistleblowers in Norway, the Gulf of Guinea and offshore Brazil. Deep-water operations everywhere are recording similar encounters."

Something vast passed the porthole, making the habitat tremble. More partial faces and bodies gathered beyond the light, some building-sized in the portions I could see, others extending into forms so enormous that the darkness concealed their true scale. They were like living cathedrals assembling in the abyss.

"They're calling others," I said. "This is a gathering."

A new voice broke through the emergency channel.

"Bethan? Can you hear me?"

Lucy Harcourt sounded clear and calm, with no trace of her earlier panic.

"I'm in the medical bay. The offshore medic thinks I'm sedated, and the onshore diving medical team is monitoring me remotely, but I'm awake. The organisms are still inside me. I can see what you see and feel what they feel. They aren't hostile, but they are desperate. They're trying to prevent a catastrophe."

"What catastrophe?"

"The drilling is destabilising something much larger. They are connected to geological structures we do not understand. Continued drilling in their territory could trigger seismic events across the waters west of Shetland and devastate northern Scottish coasts and islands."

"That matches reports from the other sites," Gareth said. "Seismic activity has increased around the encounters. The company concealed that as well."

The third face pressed nearer. Its expression changed with the realisation that I was listening instead of dismissing it.

"Every failure and shared vision has been an attempt to make us understand," Lucy said. "They have grown more intense because we kept ignoring them."

I looked into the immense eye and made a decision that violated every safety instinct I had.

"Siobhan, I'm going outside."

"Absolutely not. Bethan, that could be suicide."

"It's communication. This being has been trying to speak to us. I have to meet it halfway."

"You don't know what it will do."

"I know what we've done to it."

I climbed back into the atmospheric suit and sealed the rear hatch. The docking chamber flooded around me while the being continued to speak, its voice humming through the hull. Through the viewport, I saw surprise cross its face, followed by unmistakable relief.

"It has been waiting," I said. "All this time, it has been waiting for someone to listen."

The chamber released me into the black water. The face filled my entire field of view, its features soft and indistinct but undeniably alive. I activated the suit's external speaker.

"I'm here," I said. "I'm listening. Tell me what we need to know."

The eye closed and opened in one immense, deliberate blink. Something shifted between us: not merely contact, but understanding, the beginning of a conversation that might save both civilisations if either possessed the courage to continue it.

A finger emerged from the darkness like a pale mountain. My rational mind screamed at me to engage the thrusters, but I remained still. It was roughly eight metres long and perfectly formed, with a fingernail the size of a pub table.

When it touched my suit, I expected crushing force. Instead, it settled against me as gently as a butterfly landing on a shoulder. The sensors registered warmth through the hull.

The world exploded into light.

It was not physical light but mental illumination. Images overwhelmed me with the force of a tidal wave, yet instead of drowning me they carried me backwards through time.

I saw the waters west of Shetland thousands of years before steel installations and subsea pipelines. They were an underwater garden. Forests of kelp moved in clean currents, and shapes of impossible beauty travelled among them.

The beings had not been alone. Dozens glided through the sea like living cathedrals, their vast bodies sheltering countless smaller creatures. Whales swam beside them, and shoals of fish formed patterns as elaborate as the Blackpool Illuminations.

Then the destruction began. Ships came first, their anchors scoring the seabed. Trawling nets stripped whole ecosystems away. At last came the drilling installations, their foundations and boreholes piercing the beings' homes like spears through flesh.

"Jesus," I whispered as tears misted my faceplate. "We had no idea."

The finger pressed a little more firmly against the suit, and new images flowed into me. Equipment failures had been deliberate attempts to attract attention and halt operations. The dive teams' supposed hallucinations were shared visions, transmitted through the organisms so humans could witness what they were destroying.

Siobhan's voice reached me through the interference. "Bethan, Gareth's evidence package was transmitted. UK offshore regulators and emergency authorities have ordered an immediate precautionary suspension of drilling at the affected installations. Investigators from the Health and Safety Executive, the North Sea Transition Authority and the Offshore Petroleum Regulator for Environment and Decommissioning are being mobilised. A full investigation will follow."

The being appeared to understand. My visions shifted to other places: vast underwater cities and trenches beyond the reach of our technology, sanctuaries where its civilisation still existed in something close to its ancient harmony. Even those refuges were shrinking as industrial activity pressed into deeper water.

"There are more of you," I said. "Other places where you are still safe."

The finger withdrew, weakening the connection without severing it. The vast face came closer until I stared directly into a single enormous eye. Its intelligence was ancient beyond measure, but patient. It had waited millennia for this moment.

"We weren't trying to hurt you. We didn't know you were here."

The eye blinked. I felt something that might have been forgiveness, or perhaps only exhaustion. The being had struggled for so long that coexistence seemed almost too much to hope for.

Its face receded into the darkness. Before it vanished completely, the massive hand returned, pressing something small into
