Niro, trapped in the Correction Room, found Kael's Diary hidden behind the wall. Inside, the final secret of Kael:
"I was wrong. The Supremacy cannot be controlled. The only way is to unite the consciousness of humans, Arkanis, and machines in one vessel. But for that, a soul must be sacrificed…"
Meanwhile, Lyra was dying on the floor of the laboratory. Her blood flowed into the clone body of Rael, triggering an unexpected reaction—Rael's original consciousness from the Nexus began to take control.
"Fight it, Rael!" Lyra shouted. "You're not their tool!"
The Rael clone trembled, his eyes flickering between red and blue. "I… am not… a puppet!"
Blue-purple energy exploded, destroying the laboratory. Sylvia fell into the broken machine, her robotic body melting. "No… we were so close… to winning…"
The Rael clone helped Lyra to her feet. "My consciousness is still fragmented. You must go to the Nexus, meet Proto-Supremacy."
Outside, the metal dragon-like Supremacy was tearing into the palace. Niro appeared, wielding a new weapon—Kael's War Hammer, capable of controlling magnetic fields.
"I'll handle the dragon. You go to the Nexus!"
Lyra and the Rael clone entered the damaged Correction Machine. With both of their bloods, a portal to the Nexus opened.
In the Nexus, they met the original Rael's consciousness, fighting against the core of the Supremacy.
"Unite us," the original Rael pleaded. "Take me home."
But the Rael clone hesitated. "If we merge, I might disappear."
Lyra held both of their hands. "You are the same Rael—sacrifice and hope."
The merging began. Blinding light filled the Nexus. When it dimmed, only one Rael remained—with blue-purple eyes and a body covered in energy tattoos.
The core Supremacy roared, but this new Rael raised his hand. The Aetheris Gate appeared behind him, sucking the Supremacy into a dark dimensional abyss.
"It's over," Rael whispered, falling into Lyra's arms.
But in the corner of the Nexus, a flicker of red light sneaked through—the remnants of the Supremacy's consciousness that had escaped.
