Read Chapter 21: The Signal

Jack’s ears rang with the echo of the collapsing tower. The transmitter’s final screech had faded into the groan of stressed metal, and now the corridor around him was dark, tilting slightly to port. The signal was out. If it worked, he’d know soon enough. If it didn’t, the station would simply keep humming its sick, melodic song.

He pushed off the bulkhead, drifting toward the stairwell that led up to the main deck. His suit’s helmet light cut a weak cone through the gloom. Every few seconds, he checked his wrist gauge—oxygen fine, pressure stable. The mark on his hand throbbed, but distant now, like a memory of pain rather than the thing itself.

Then he heard it.

A low moan, drawn out and human, filtered through the habitat’s hull. It wasn’t the organism’s hum. This was a voice—raw, exhausted, almost relieved. Then another, and another, until the station rang with a chorus of them, rising and falling like a tide pulling back from shore.

Jack froze, his hand on the ladder. He’d heard dying men make sounds like that. He’d heard fear and rage and resignation. This wasn’t any of those. This sounded like waking up.

He climbed.

Deck 2 was lit by emergency strobes, red and amber pulsing in slow, arrhythmic waves. Crew members lay sprawled in the corridors—some crumpled against the walls, others face-down on the grating, limbs splayed at odd angles. A woman—Nguyen, the comms officer—was on her knees, hands gripping her own skull, rocking gently. Her eyes were open. They were clear.

Jack moved past her, stepping carefully over a prone figure he didn’t recognize. The man’s chest was rising and falling. Alive.

A shudder ran through the hull, deep and bass-heavy, like the station itself was exhaling. The lights flickered once, twice, then steadied. The moaning faded, replaced by the quiet hiss of air circulation and the distant groan of settled metal.

The hum was gone.

Jack stood still for a long moment, listening. He’d grown so used to the entity’s presence—that low, insistent thrum at the edge of his thoughts—that its absence felt like a void. A silence that pressed against his ears. He flexed his gloved hand. The mark was still there, but it felt cooler now. Dead tissue, maybe. Or scarred over.

He climbed the final ladder to Deck 1, where the main hatch led out to the airlock. The corridor was empty. No moaning, no bodies, no movement. Just the faint green of the exit signs and the rust-colored stains left by earlier events.

The door to the flooded medical bay was where Sam had left it, wedged open with a fire extinguisher. Water still lapped at the threshold, dark and still. Jack leaned in, sweeping his light across the space.

Sam was crumpled in the corner, the straps of the stretcher hanging loose around his wrists. His head was bowed, his breathing shallow but steady. Beside him, the sample container floated in the murky water, its seal intact.

Jack waded in, the cold seeping through the seals of his suit. He reached Sam, crouched, and pressed two fingers to the man’s neck. Pulse was there, thready but present.

“Sam,” Jack said. “Hey. You with me?”

Sam’s eyes fluttered open. They were unfocused at first, then sharpened. He blinked, looked around the room, then up at Jack.

“Mercer,” Sam said, voice cracked. “It’s quiet.”

“Yeah,” Jack said. “It is.”

Sam’s brow furrowed. “Did it work? The signal?”

“I don’t know yet.” Jack helped him untangle the straps. “I need to find Voss. And I need to check the tower.”

“The tower’s gone,” Sam said, rubbing his wrists. “I heard it fall.”

“The signal went out before it did. Whether it reached—whether it worked—” Jack shook his head. “You stay here. Rest.”

Sam nodded, too weak to argue. Jack left him and made his way toward the collapsed section, the path he’d carved through twisted metal and ruptured panels. The way was treacherous, and his light flickered in the dark.

He found Voss at the junction where she’d made her stand.

She was lying on her back, one arm draped over her chest, her face pale beneath the grime. Her flare launcher lay a few feet away, spent. The two transformed crew members were slumped against the far wall, their bodies still, their eyes closed.

Jack knelt beside Voss. He pulled off his glove and pressed two fingers to her throat. A pulse. Weak, but there.

“Voss,” he said. “Voss, wake up.”

She didn’t respond. But she was breathing.

Jack sat back on his heels. The station was quiet around him—no hum, no moan, no presence threading through the walls. Just the sound of his own breath and the faint drip of water somewhere distant.

He lifted his head, listening. The organism’s malevolent intelligence had pulled back, like a tide receding from a shore it had claimed. Whether it was gone for good, or just waiting, he couldn’t say.

But for now—for this one breath, this one heartbeat—the station was quiet.

Jack looked down at Voss, then up at the hatch that led to the surface. No rescue was coming. Not today. Not for a long time. The comms were still down, the tower was wreckage at the bottom of the Atlantic, and the crew was scattered and dazed.

But they were alive.

And that, for now, was enough.
