The darkness was total.
Elias didn't need to see. He'd been trained for this. The moment the lights died, his body moved on instinct. He dropped low, sweeping his leg in a wide arc. It caught Asher's ankle, and the man went down hard, the detonator skittering across the floor.
"It's over!" Elias shouted.
But Asher was already moving. He rolled, kicked out blindly, and connected with Elias's knee. Pain exploded through Elias's leg, but he didn't fall. He lunged forward, grabbed a handful of Asher's torn shirt, and slammed him against the floor.
"Where is it?" Elias demanded. "Where's the detonator?"
A laugh came from the darkness. "You think that matters? The charges are already armed. The rig dies in twenty minutes. You and your pathetic survivors die with it."
Elias pulled back his fist and swung. It connected with Asher's jaw, and the laugh stopped. But Asher didn't stay down. He shoved Elias back and scrambled to his feet, moving fast despite his wounds.
A flashlight clicked on somewhere behind Elias. Jesus. The beam cut through the darkness, illuminating Asher standing near a wall panel.
"You should have stayed down," Asher said.
He pressed something on the panel. A hidden door slid open, revealing a narrow escape tunnel. Asher slipped through, and the door slammed shut before Elias could reach it.
"Damn it!" Elias hammered the panel, but it wouldn't budge.
"Let him go," Jesus said. "We have bigger problems."
He was right. The clock was ticking. Twenty minutes. Maybe less.
Elias turned. The room was a wreck. Bodies of hunters lay scattered, some unconscious, some dead. In the cages at the far end, the survivors were still huddled together. Becky was there, her eyes wide. Ava held the child. Lauren and Henry were helping the older prisoners to their feet.
"Everyone out!" Elias shouted. "Now! The rig is going to blow!"
They moved fast. Elias and Jesus took point, clearing the corridor while the others helped the survivors. The air grew heavier with each step, thick with the smell of fuel and salt and fear.
"The helipad," Elias said. "It's our only chance."
"The ship," Mateo called from behind. "It's getting closer. I saw it from the porthole."
"Then we signal it," Elias said. "We get everyone on board."
"If it's friendly," Henry muttered.
Elias didn't answer. He didn't have time for doubt.
They climbed through the rig, moving as fast as the weakened survivors could manage. The child stumbled, and Ava picked him up, carrying him despite her own exhaustion. The old man from the cage leaned heavily on Mateo, his breathing ragged.
Every few seconds, the rig groaned. Metal shrieked. Somewhere below, water rushed into flooded compartments. The countdown was real.
They reached the main deck. The wind hit them hard, carrying salt spray and the distant thrum of engines. The supply ship was closer now, maybe a quarter mile out. Its deck lights blazed in the gray afternoon light.
And it was moving away.
"No," Becky whispered. "It's leaving."
Elias ran to the edge of the deck, waving his arms. "Hey! We're here! We need help!"
The ship continued on its course, not slowing. A moment later, a voice crackled over the rig's speakers—the watcher, calm and mocking.
"Did you really think we'd rescue you? The Horizon is not a lifeboat. It's a containment vessel. If the rig falls, the evidence must fall with it."
Elias's blood went cold. The ship wasn't coming to help. It was ensuring no one escaped.
"Then we use the lifeboats," Jesus said.
"Too late," Lauren said. "The lifeboat station was in the lower levels. It's flooded now."
"Then the helicopter." Elias turned, scanning the helipad. The helicopter still sat there, its rotors still, its windows dark. "Can it fly?"
Mateo shook his head. "It's stripped. No fuel, no engine. It's just a shell."
Elias's mind raced. The rig was dying. The ship was leaving. The hunters were either dead or gone. The creature was still loose. They had twenty minutes.
"There's another way," Henry said quietly. "The observation deck. There's a radio mast. If we can climb it, we might be able to signal a passing ship. A real one."
"How do you know there's a real ship?" Becky asked.
"I don't. But it's better than waiting to die."
Elias looked at the survivors. Twelve frightened people, some barely able to walk. Climbing a radio mast in high wind with no safety gear was suicide. But staying here was also death.
"Then we move," he said. "The observation deck is above us. We'll climb in stages. Mateo, Lauren, you take the lead with the stronger survivors. Jesus, Ava, you bring up the rear. I'll scout ahead."
"And the creature?" Mateo asked.
"If it finds us, we fight. Now go."
They started climbing. The stairs were slick with moisture, and the wind tore at their clothes. The survivors moved slowly, their bodies weak from weeks of captivity. Elias pushed ahead, clearing each landing before signaling the others forward.
Halfway up, the first explosion hit.
The rig shuddered, and a fireball erupted from the lower decks, sending a column of black smoke into the sky. The shockwave knocked several survivors off their feet. A woman screamed.
"Keep moving!" Elias shouted.
They climbed faster. The explosions came more frequently now, each one closer than the last. The rig was tearing itself apart.
They reached the observation deck just as another blast ripped through the corridor behind them. The glass wall shattered, spraying shards across the helipad below. The wind screamed through the broken windows.
"The mast!" Henry pointed to a metal ladder bolted to the side of the structure. It climbed fifty feet to a small platform where the radio antenna stood.
"I'll go," Elias said.
"I'm coming with you," Becky said. She was shaking, but her eyes were determined. "You'll need someone to operate the radio."
Elias hesitated, then nodded. "Stay close."
They climbed. The ladder was cold and slick, the rungs vibrating with each explosion. The wind tried to rip them off, but they held on, fingers white-knuckled.
The observation deck fell away below them. The ocean stretched in every direction, gray and endless. The supply ship was a dark speck now, still moving away.
They reached the platform. The radio mast stood before them, a skeletal tower of rusted metal. A small control box was bolted to its base.
Becky opened the box. "The transmitter's intact! I just need to power it up."
"Hurry!"
She worked frantically, her fingers flying over the wires. Elias stood guard, his eyes scanning the horizon for any sign of rescue.
A sound below. A roar.
The creature.
It was climbing the ladder.
"Becky, faster!"
"I'm trying!"
The creature's claws scraped against the metal, its massive bulk moving impossibly fast. It was less than thirty feet below now.
Elias raised his rifle. He had eight rounds left. Not enough to stop that thing, but maybe enough to slow it down.
He fired. The first shot hit the creature's shoulder, and it roared. The second hit its face, and it recoiled. But it kept climbing.
"Becky!"
"Got it!" She flipped a switch, and the transmitter hummed to life. "I'm broadcasting on all frequencies!"
A voice crackled through the speaker—a woman's voice, crisp and professional.
"This is the USS Halcyon. We received your distress signal. We are two hours out. Can you hold?"
Elias grabbed the microphone. "Negative! The rig is collapsing! We need extraction now!"
"Understood. We're launching a rescue helicopter. ETA fifteen minutes."
Fifteen minutes. They didn't have fifteen minutes.
The creature was almost to the platform. Elias fired again, hitting it in the chest. It didn't stop.
"Becky, get behind me!"
She moved, and Elias emptied the rest of the magazine. The creature staggered but kept coming. It grabbed the edge of the platform, its claws digging into the metal.
Elias dropped the rifle and pulled the pistol from his waistband. One shot left.
The creature pulled itself onto the platform. Its blind eyes fixed on Elias, its mouth open in a horrifying grin.
"End of the line," it growled.
Elias raised the pistol. "Not yet."
He fired.
The bullet hit the creature between the eyes. It stopped, swayed, and then toppled backward off the platform, its body crashing through the shattered glass below.
Elias stood there, breathing hard. The rig was still exploding. The rescue helicopter was fifteen minutes out. They might not make it.
But they had a chance.
"Come on," he said to Becky. "We need to get everyone to the helipad."
They climbed down, the rig groaning beneath them. The survivors were huddled on the observation deck, their faces pale with terror.
"The helicopter's coming!" Elias shouted. "Fifteen minutes! We need to be on the helipad when it arrives!"
They moved. The stairs were damaged, but they found an alternate route. The explosions were less frequent now, but the fires were spreading.
They reached the helipad just as the first helicopter appeared on the horizon. It was small, military-style, with a red cross on the side.
"Here!" Elias waved his arms. "We're here!"
The helicopter circled once, then began its descent. The wind from the rotors whipped across the deck, nearly knocking them over.
The door slid open, and a man in a flight suit leaned out. "How many?"
"Sixteen!" Elias shouted back.
"We can take eight at a time! We'll have to make two trips!"
Elias turned to the group. "Women and children first! Ava, Becky, Lauren—get the child and the weakest survivors on board!"
They loaded the first group. The helicopter lifted off, disappearing toward the distant ship.
The second group waited. The rig was still burning. The fires were spreading, and the lower decks were gone.
"Where's Henry?" Mateo asked suddenly.
Elias looked around. Henry was missing.
"He was here a minute ago," Lauren said.
A shout came from the far side of the helipad. Henry was standing at the edge, looking down at the water.
"Henry! Come on!" Elias shouted.
Henry didn't move. He turned, his face calm. "I'm not coming."
"What? Why?"
"Because I'm part of this," Henry said. "I helped create this nightmare. I deserve to go down with it."
"That's insane! Get over here!"
Henry shook his head. "Go. Save the others. I'll stay."
Elias ran toward him. But before he could reach the man, another explosion rocked the helipad. A section of the deck collapsed, sending metal crashing into the sea.
Henry was still standing there, untouched. He smiled.
"Goodbye, Elias. Make it count."
He stepped backward, off the edge, and disappeared into the waves.
Elias stood frozen. The helicopter was returning for the second group. But Henry was gone.
"Elias!" Jesus grabbed his arm. "We have to go!"
He let himself be pulled toward the helicopter. The second group climbed aboard, squeezing into the cramped space.
The helicopter lifted off. Below them, the rig was consumed by fire. The structure groaned and collapsed, folding in on itself like a dying beast.
Elias pressed his face against the window. The Prometheus Platform was gone.
But somewhere in the distance, the supply ship still sailed, carrying Asher and his hunters.
And the experiment wasn't over.
Not even close.
As the helicopter turned toward the USS Halcyon, Elias saw something on the horizon. A shape. Dark and massive, rising from the water.
It wasn't a ship.
It wasn't a rig.
It was something else entirely.
And it was moving toward them.
