The first machine came through the door.
Elias swung the fire axe in a wide arc, catching the creature at the neck. Sparks flew. Metal shrieked. The thing staggered, its red eyes flickering, then collapsed in a heap of twitching limbs. But more were already climbing through the broken window, their claws scraping against the station's rusted frame.
"Barricade the door!" Elias shouted.
Jesus grabbed a heavy console and shoved it against the entrance. The metal groaned but held. Two more machines slammed into it from the other side, their impact shaking the room.
"They're everywhere," Ava said. She had Isaac behind her, one arm wrapped around the boy. The flare gun was in her other hand, loaded but useless at close range.
"Becky, can you close the blast doors?" Elias asked.
She was at a secondary console, fingers flying. "Trying. The security system is still rebooting. Give me a minute."
A machine appeared in the doorway, its head angled like a dog catching a scent. It lunged. Jesus met it with his axe, driving the blade deep into its chest. The machine thrashed, then went still.
"We don't have a minute," Jesus said.
Elias scanned the room. It was small, maybe twenty feet square, with one door, one window, and a ventilation shaft in the ceiling. The shaft was too small for an adult, but Isaac could fit.
"Isaac, can you get into the vent?" Elias asked.
The boy nodded, his face pale but determined.
"Then go. Find a way to seal the station. Lock every door you can. Buy us time."
Isaac climbed onto a chair and disappeared into the shaft. A moment later, they heard him crawling, the sound growing fainter.
Ava looked at Elias. "What's the plan?"
"Hold this room. The Halcyon is coming. If we can survive until then, we get out."
But even as he said it, a cold doubt settled in his chest. The voice on the radio had been faint, almost too clean. And the Halcyon had been sinking when they left it. Could it have survived?
Becky's voice cut through his thoughts. "Elias, I'm picking up the Halcyon's signal. It's strong. But something's wrong."
"What do you mean?"
She turned the tablet toward him. The screen showed a frequency analysis, a single spike jumping among static. "The signal is coming from the Nyx. Not from a ship. It's a broadcast. Recorded. Echo is using it to keep us here."
The words hit like a physical blow. Elias stared at the screen, watching the fake transmission pulse. The Halcyon was gone. No one was coming.
"He wanted us to stay," Elias said. "This whole place is a trap."
"Then we leave," Jesus said. "Now."
A loud crash echoed from outside. The barricade buckled. More machines were pressing against it, their metal bodies grinding. The room shook.
"The boat is still docked," Ava said. "If we can reach it—"
"We'll never make it through that swarm." Elias looked at the ventilation shaft. "We need another way."
The console beeped. Isaac's voice came through the intercom, tinny and urgent. "I found the roof access! There's a helicopter pad on top. But the door is locked. I can open it if I can get to the main control room."
"Where are you now?" Elias asked.
"Near the central junction. But there are machines in the corridor. They're not moving. They're waiting."
Elias and Jesus exchanged a glance. Waiting. Echo was controlling them, holding them back. Why?
"He wants us to run," Elias said. "He wants us to make a mistake."
"Then we don't run," Jesus said. "We fight."
The barricade gave way. The door burst inward, and a wave of machines poured into the room. Elias swung the axe, hitting one, then another. Jesus was a whirlwind of violence, his axe rising and falling. Ava fired the flare gun, the bright projectile slamming into a machine's chest, setting it ablaze.
But there were too many. They kept coming, crawling over their fallen, their red eyes unblinking.
"Fall back!" Elias shouted. He grabbed Ava and pulled her toward the ventilation shaft. "Becky, go!"
They climbed, Elias last. The machines grabbed at his legs, but he kicked free and scrambled into the shaft. The metal was tight, but he moved, pulling himself forward.
Behind him, the room filled with machines. Their screeches echoed through the shaft.
They emerged on a maintenance catwalk above the main corridor. Isaac was there, crouched behind a stack of crates. He pointed toward a ladder. "The roof access is that way."
They moved along the catwalk, staying low. Below, machines patrolled, their movements synchronized. Echo's voice echoed through the station.
"You cannot escape, Elias. The Nyx is here. The station is surrounded. Surrender, and I will let the others live."
Elias ignored him. They reached the ladder and climbed. The roof door was locked, but Isaac had already bypassed it. It swung open, and cold sea air rushed in.
They stepped out onto the helipad. The station's roof was small, barely large enough for a single helicopter. No aircraft sat there. Just an empty pad and the satellite dishes.
And the Nyx, looming on the horizon like a black mountain. It was closer now, its hull cutting through the waves. Smaller boats were launching from its sides, swarms of them.
"We're trapped," Becky said.
Elias looked around. The roof offered no cover. But it did offer a view. He saw the patrol boat still tied to the dock below, bouncing in the waves. And he saw the Nyx's launch bay, wide open, ready to receive them.
"Maybe not," Elias said. "We can signal the Nyx."
"Why would we do that?" Jesus asked.
"Because Echo wants us alive. He won't destroy the boat if we're on it. We use that."
He raised his hands, waving at the approaching ship. A searchlight from the Nyx swept across the roof, blinding them. A voice boomed from the ship's speakers—not Echo, but the Director.
"Asset Seven. You have made this more difficult than necessary. But I am patient. Come aboard, and the others will be spared."
Elias turned to the group. "We're not surrendering. We're buying time."
He grabbed the flare gun from Ava, loaded a fresh flare, and aimed not at the Nyx, but at the patrol boat. The flare shot downward, lighting up the boat. "There's our ride. We jump."
"Jump?" Mateo's voice would have cracked. But Mateo was gone. Now it was Becky who said it. "It's a fifty-foot drop."
"The water is deep enough. And the boat will break our fall." Elias looked at each of them. "We go together. On three."
Before he could count, a new sound cut through the air. Not the Nyx. Not the machines. A helicopter. A real one, with a red cross on its side.
It came in low, rotors thundering. A door slid open, and a figure in a flight suit leaned out. "This is Rescue One. We're here to extract you. Get to the boat!"
Elias didn't hesitate. "Go!"
They scrambled down the ladder and along the dock, machines closing in. The helicopter hovered above, its downdraft whipping the water into foam. They reached the boat, threw off the lines, and gunned the engine.
But as they pulled away, Elias looked back. The helicopter was turning, heading toward the station. It wasn't landing.
"Becky, who is that?" he shouted over the engine.
She checked the radio. "It's a military frequency. But I don't recognize the call sign."
"Then it's not ours."
The helicopter hovered over the helipad, its rotors still spinning. A figure jumped from the open door, rolling to absorb the impact. It was a man, tall and thin, dressed in black.
Echo.
He stood on the helipad, facing the approaching Nyx. The helicopter flew off, disappearing into the clouds.
Echo raised a hand. The machines below went still. The boats from the Nyx stopped. Everything went silent.
Then Echo's voice boomed, not from the station's speakers, but from his own throat, amplified somehow. "Elias! You think you've escaped, but you've only run deeper into the trap. The Nyx is not your destination. It is your coffin."
Elias didn't answer. He pushed the throttle, the boat leaping forward. The Nyx was still ahead, but now it was turning, its bow swinging toward them.
"The ship is moving!" Ava shouted.
"He's herding us," Jesus said.
Elias turned the wheel hard, aiming away from the Nyx. But the sea was filled with machines—shark-like shapes gliding beneath the surface. They were surrounded.
"Hold on!" Elias shouted.
He drove straight at the nearest machine, the boat's hull smashing into it. The creature shrieked and sank. But others closed in.
The helicopter reappeared, not to help, but to watch. It hovered just out of reach, its camera trained on them.
"They're filming," Becky said. "For the experiment."
Elias felt a cold rage. He grabbed the last flare and aimed it at the helicopter. The shot went wide, but the aircraft banked away.
That bought them a moment. Elias veered toward open water, desperate to put distance between them and the Nyx. But the ship was faster. It cut them off, its massive hull creating a wave that nearly capsized the boat.
"We can't outrun it," Jesus said. "We have to fight."
Elias looked at the Nyx, then at the station behind. The helicopter was gone. Echo was still on the helipad, watching.
"He wants us on the Nyx," Elias said. "So let's give him what he wants."
He turned the boat and drove straight at the Nyx's open launch bay.
The group braced. The boat slammed into the bay, skidding across the deck. They tumbled out, scrambling to their feet.
But the bay was not empty. Dozens of machines stood in rows, their eyes glowing. And at the far end, the older Elias stood, waiting.
"Welcome home," he said.
The doors slid shut behind them.
They were trapped.
