Kai was dying.
He lay in the rubble, his body broken, his blood pooling on the cold stone, his vision fading. The threads of the Network were flickering, five thousand goblins, five thousand minds, all of them feeling his pain, his weakness, his slow slide into darkness.
Above him, Riya stood in the light. Her eyes were white fire. Her scar blazed like a sun. The Core was wearing her face, using her voice, laughing with her mouth.
"You are nothing, Subject 11. You gave up your strength. You gave up your hunger. You gave up everything for a pack of goblins and a broken city. And now you will die for a girl who was never meant to survive."
Kai couldn't answer. His lungs were filling with blood. His heart was slowing. His hands were cold.
"Cognitive Load: 950,000," Red said. "Your body is failing. Your heart rate is 30 beats per minute. Your blood pressure is dropping. You have less than two minutes before..."
Red stopped.
"Before what?" Kai's thought was barely a whisper.
"Before you die."
The Core laughed. Riya's body lifted off the ground, her arms spread wide, her scar blazing like a second sun.
"The girl will watch you die, Subject 11. And then she will belong to me. Forever."
Kai's eyes were closing. The darkness was pulling him under. He could feel the threads of the Network fraying, five thousand goblins, five thousand lives, all of them slipping through his fingers.
"Kai," Blue said softly. "You cannot win. Not like this."
"I know."
"But you can survive. If you take what Red has been hiding."
Kai's eyes opened. Just a crack. Just enough.
"What?"
Red was silent for a long moment. Then:
"Your father sealed the Assimilation Protocol. Not to destroy it. To protect you. He knew you would need it. When you were ready. When there was no other choice."
"You have a backup."
"Yes. Stronger than before. Your father... improved it. Before he sent you. Before he died. He knew what you would face. He knew what you would become."
"And you hid it from me."
"Your father's orders. Only when there was no other way. Only when death was certain. Only when..."
"When I was dying."
"Yes."
Kai looked at Riya. At the Core wearing her face. At the girl who was still in there somewhere, drowning in light, waiting for him to save her.
"Do it."
"Kai—"
"Do it."
The world went white.
Pain exploded through Kai's body—not in his chest, not in his arms, but in his mind. The Assimilation Protocol blazed to life, stronger than before, hungrier than before, tearing through his broken body like fire through dry grass.
"Assimilation Protocol activated," Red said. "Biological data detected. Source: The Core. Warning: The Core is not biological. Assimilation of non-biological entities may result in—"
"I don't care."
Kai reached for the light. For the Core. For the thing that was wearing his friend's face.
His hand closed around nothing. But his will closed around everything.
The Core screamed.
"What are you doing?! You cannot—you are nothing—you are—"
"I am Subject 11," Kai said. "And you are in my friend."
He pulled.
The light bent. The Core's will twisted. Riya's body arched, her mouth open in a silent scream, her scar blazing like a dying star.
"Assimilation in progress," Red said. "Warning: Cognitive Load exceeding safe limits. 1,000,000... 1,500,000... 2,000,000..."
Kai's mind was burning. His body was breaking. The Core was fighting him, tearing at him, trying to consume him from the inside out.
"You cannot hold me, Subject 11. I am eternal. I am the end of all things. I am—"
"You are nothing."
Kai pulled.
The Core's light began to move. Slowly at first. Then faster. It was flowing out of Riya, out of her scar, out of her eyes, her mouth, her hands. Flowing into Kai.
"Assimilation in progress. Cognitive Load: 3,000,000... 5,000,000... 10,000,000..."
Kai's body was shaking. His blood was boiling. His mind was being torn apart. He couldn't hold it. The Core was too vast. Too ancient. Too hungry.
"Kai—" Blue's voice was desperate. "You cannot assimilate the Core. It is too large. It will destroy you."
"Then I'll put it somewhere else."
He looked at the bodies. The creatures the pack had left behind. Grey skin. Red eyes. Dead.
He chose the smallest one.
"Assimilation transfer initiated," Red said. "Redirecting Core data to target organism."
The light flowed out of Kai. Into the dead creature. Its body convulsed. Its skin cracked. Its eyes blazed white.
"No—" The Core's voice was different now. Afraid. "You cannot—I am eternal—I am—"
"You are nothing."
Kai pushed.
The creature's body began to glow. Brighter and brighter, hotter and hotter. Its skin was cracking. Its bones were breaking. The Core was inside it, filling it, overflowing.
"Cognitive Load: 50,000,000... 100,000,000... 200,000,000..."
The creature's body was vaporizing. Its cells were breaking apart. Its form was dissolving into light.
"Assimilation complete," Red said. "Core data transferred. Target organism destroyed. No biological remains detected."
The light faded.
Riya fell.
Kai caught her. His arms were broken. His body was broken. But he caught her. She was cold. Her face was pale. Her scar was dim, closed, just a scar again.
"Riya."
She didn't move.
"Riya."
Her eyes opened. Brown. Dark. Tired. Hers.
"Kai..."
"Hey."
"You're bleeding."
"I know."
"You're dying."
"I know."
She raised her hand. Her fingers touched his face. They were warm.
"You saved me."
He smiled. It was weak. Broken. But real.
"We saved each other."
Behind them, the creature was gone. No ash. No remains. No trace. The Core had been inside it, and then it had been nothing. The cells had been destroyed at the molecular level. There was no sign that anything had ever been there.
"Cognitive Load: 50,000. Stabilizing," Red said. "Assimilation Protocol deactivated. Core data purged. No residual traces detected."
Kai held Riya in his arms. The goblins were gathering around them, their threads pulsing with relief, with hope, with something that might have been love. Tik was at his feet, chirping softly. Warden stood at the edge of the light, watching.
"Is it gone?" Riya whispered.
Kai looked at the place where the creature had been. At the empty stone. At the darkness beyond.
"The Core is gone," he said. "The part that was in you. The part that was watching. The part that was trying to take you."
"But the Core itself..."
"Is still out there. In the Bleed. Waiting."
She closed her eyes.
"Then we'll deal with it later."
He laughed. It was weak. Tired. But real.
"Later."
In the darkness beyond the walls, the beast watched. Its golden eyes were fixed on the boy who had just done the impossible. Who had taken something ancient and terrible and destroyed it. Who had saved a girl from a fate worse than death.
The beast had seen many things since the world ended. It had seen cities fall. It had seen empires crumble. It had seen the death of hope and the birth of monsters. But it had never seen anything like this.
The boy was weak. His body was broken. His mind was frayed. But his will was something else. Something the beast had not encountered in a very long time.
The beast lowered its head. Not in submission. Not in acknowledgment. In something it had not felt since before the Collapse.
A question.
What would the boy become, when he was whole again?
The beast slipped back into the darkness. It would watch. It would wait. And when the time came, it would know.
