Bathyal-7

The submersible smelled like someone else's sweat. Lena noticed it the moment the hatch sealed - a stale, human sourness baked into the padding of the seat, into the rubber grips on the armrests, into the headrest where someone had pressed their skull for hours on a previous dive. She adjusted the harness across her chest and tried not to think about who had sat here last. The manifest said the sub had been used on the recovery mission two years ago. The manifest did not say whether the person who'd sat in this seat had come back up. "Depth at six hundred meters," Harlan said from the pilot's chair. He did not look at her. He watched the instruments the way a man watches a dog he does not trust. "Pressure's nominal. Descent rate steady." Outside the porthole, the ocean had already eaten the sun. What remained was a blue so deep it looked like the memory of a color - not blue itself, but the last thing blue had been before it gave up. Lena pressed her forehead to the glass. Somewhere below them, four thousand meters below them, Bathyal-7 sat on a shelf of rock that was not rock. She had read the geological survey. She had read it four times. The language was careful in the way corporate language is careful when it is trying not to say what it knows. *Calciumite substrate of indeterminate biological origin. Noniteiteite non-ite non-* She blinked. The sentence in her memory had stuttered. That happened sometimes - a word catching on itself like a skipping record. Fatigue. She hadn't slept in thirty-one hours. "You all right?" Harlan asked. "Fine." "You went somewhere." "I'm here." He grunted. The sub groaned around them - a low, intestinal sound, the hull flexing under pressure that increased with every meter. Lena counted. She always counted. It was the thing she did instead of being afraid. *Seven hundred. Eight hundred. Nine hundred.* At twelve hundred meters, the last of the light died. The ocean outside the porthole was not dark the way a room is dark when you turn off the lamp. It was dark the way the inside of a body is dark - wet, close, pressing against the glass as if it wanted in. The sub's external floods cut two cones of white into the black, and in those cones, nothing moved. That was worse than if something had. Empty water at twelve hundred meters should have had particulate - marine snow, the slow rain of dead things falling from the surface. There was none. The water was clean. Lena had spent eleven years studying the deep ocean. She had never seen clean water at depth. The absence registered in her body before her mind caught up - a tightening across her shoulders, a dryness at the back of her throat. "Harlan." "I see it." "There's no snow." "I know." "That's not -" "I know what it's not." He said it the way you close a door. She let it close. They descended in silence. The sub's instruments ticked and hummed. The hull sang a single low note that changed pitch as the pressure climbed - a sound like a throat being slowly squeezed. Lena watched the depth gauge. The numbers climbed with the patience of something that had been counting long before she arrived. *Two thousand. Twenty-five hundred. Three thousand.* At thirty-eight hundred meters, the floods caught something below them. It was white. Vast. It stretched beyond the reach of the light in every direction - a pale, ridged surface that looked, from above, like a frozen sea. But it was not ice. The ridges were too regular. The texture was too fine. It looked like - "Bone," Lena said. Harlan did not answer. The sub descended over the bone reef. Up close, the surface was a nightmare of fused anatomy - ribs locked into jawbones, vertebrae spiraling into shapes that belonged to no known animal, skulls the size of cars half-buried in a calcium matrix that pulsed, faintly, with a rhythm Lena could feel through the floor of the sub. A heartbeat. Or something that had learned what a heartbeat was and was practicing. "There," Harlan said. He pointed. Bathyal-7. The station sat on a ledge of the reef like a barnacle on a whale. Six cylindrical modules arranged in a ring, connected by pressurized corridors, all of it crusted with two years of deep-sea growth - pale tendrils, translucent fans, things that looked like fingers if you let your eyes soften. At the center of the ring, the Throat descended into the reef itself, a steel tube punched straight down into the bone. The lights were on. Lena stared. "Harlan. The power was supposed to be off." "It was off. When we left it, it was off." "Then who turned it on?" He did not answer. His hands on the controls had gone still. She looked at his fingers. They were shaking. The sub docked at Module One with a sound like a jaw closing. The docking clamps engaged. The pressure equalized with a long, exhausted hiss. Harlan ran the atmospheric checks twice. Oxygen, nitrogen, carbon dioxide, trace gases - all within range. The air inside Bathyal-7 was breathable. It should not have been. Two years without maintenance, without scrubbers, without anyone cycling the filters. The air should have been a toxic soup of CO2 and mold. Instead it was clean. Like the water. Lena unclipped her harness. "Wait," Harlan said. She looked at him. In the green light of the instrument panel, his face had the texture of something carved. The lines around his mouth were deep. His eyes were fixed on the hatch. "Last time I came through that door," he said, "I found a handprint on the wall of Module Four. Right at eye level. Like someone had pressed their palm flat against the metal and held it there. The print was - it was too big. The fingers were too long. And there were too many of them." He swallowed. "I counted. There were nine." Lena looked at the hatch. The metal was cold. She could feel the cold radiating from it - not the cold of deep water, but something older, something that had been cold for a long time and had gotten good at it. "We have a job to do," she said. "I know we have a job." "Then open the hatch." He opened the hatch. The air that came through was cold and smelled like copper. Like a mouthful of pennies. Like blood that had been sitting in a bowl for a week, oxidizing, turning dark, turning into something that was not quite blood anymore but remembered being blood. The corridor beyond was lit. Fluorescent strips ran along the ceiling, buzzing with the thin, insistent sound of electricity being used by something that did not fully understand how electricity worked. The lights flickered. Not randomly - rhythmically. A pulse. The same pulse she had felt through the floor of the sub when they passed over the reef. Lena stepped through. The corridor was narrow, maybe four feet across. The walls were steel, riveted, institutional. Water stains ran down from the ceiling in brown streaks that looked, in the flickering light, like dried tear tracks on a metal face. The floor was grated. Through the grating she could see pipes, cables, and below that - darkness. The kind of darkness that looked back. She walked. Her boots rang on the grating. Each step sent a small echo down the corridor, and each echo came back wrong - a half-beat late, a half-tone lower, as if something down the corridor was repeating her footsteps but couldn't quite get the timing right. "Module Two is straight ahead," Harlan said behind her. His voice was flat. Controlled. The voice of a man who had decided that if he kept his voice level, the rest of him would follow. "Crew quarters. That's where we set up." "What's in Module Four?" "Lab space." "What else is in Module Four, Harlan?" A pause. She heard him breathe. "That's where we found the wall." "What wall?" "The wall that wasn't there before." She stopped walking. She turned. In the flickering light, Harlan's face was a series of snapshots - lit, dark, lit, dark - and in each dark frame, she could have sworn his expression was different. Afraid. Angry. Afraid. Something else. "What do you mean, wasn't there before?" "The station has six modules. When it was built, Module Four was open-plan. One big lab. When we came back for the recovery, there was a wall across the middle of it. Floor to ceiling. Sealed. No door. No seam. Like it had grown there." "Grown." "I know how it sounds." "What's behind it?" "We don't know. We couldn't cut through it. The material - it wasn't steel. It wasn't concrete. The drill bits broke. The saw blades melted. We hit it with everything we had and it just sat there. Cold. Smooth. Like it was waiting for us to stop." Lena turned back toward the corridor. The lights pulsed. The echo of her last footstep was still coming back, slower now, dragging itself along the metal like something crawling. "I need to see it," she said. "Not tonight." "Harlan -" "Not tonight, Lena. Please." The *please* stopped her. Harlan did not say please. Harlan said *move* and *check* and *copy that* and *we're done here*. Please was not in his vocabulary. Please meant something had gotten inside his vocabulary and rearranged it. "Okay," she said. "Not tonight." They walked to Module Two. The crew quarters were small - six bunks stacked in pairs, a shared head, a galley kitchen with supplies that PFC had sent down on the cargo sub a week earlier. Everything was where it should be. Canned food. Water. Medical kit. Emergency beacon. Lena chose the bunk farthest from the door. She sat on it. The mattress was thin. Through it, she could feel the frame, and through the frame, she could feel the floor, and through the floor - faintly, impossibly - she could feel the pulse. She lay down. She closed her eyes. And from somewhere deep inside the station - from the direction of the Throat, from below, from the place where the steel met the bone - she heard a voice. It was Maren's voice. It said her name. It said her name the way Maren used to say it - soft, with the emphasis on the second syllable, the way you say a word you've been carrying in your mouth all day and have finally decided to let go of. *Lena.* And then, quieter, in a syntax that did not belong to any language Lena knew: *Down come. We here. We here. We waiting you so long.* The lights pulsed. The station breathed. And four thousand meters above her, the ocean closed over the last place anyone would ever think to look.
