The maintenance level under the District 3 transit hub smelled like rust and standing water. It was the kind of place that existed in every city necessary infrastructure that nobody maintained past the point of functional, full of pipes and relay boxes and the bones of systems that kept things running above ground while being completely invisible themselves.
Kazuki moved through it in civilian clothes. No suit activated. No HUD. Just his own eyes adjusting to the dark and the faint pulse of the Core against his sternum.
He found him in the third corridor.
Dread was sitting against the wall with his knees pulled to his chest and his head tilted back against the concrete. He looked like someone who had been sitting in that exact position for a very long time and had stopped noticing the discomfort of it.
He was younger than Kazuki expected. Not much older than him. Maybe nineteen. Dark skin. Short hair. A suit that looked like the Mark II's older, more damaged cousin — black nanotechnology, the same matte finish, but cracked in places, the cracks glowing a deep, unhealthy black rather than any color that belonged in a living thing.
The black lightning was visible even now. Small arcs of it tracing his neck and jaw. Not dramatic. Not cinematic. Just constant, quiet, painful-looking.
His eyes were open. He had heard Kazuki coming long before Kazuki arrived.
"Took you longer than I thought," Dread said. His voice was rough. Not aggressive. Just worn.
"I had to think about it," Kazuki said.
"Fair." Dread looked at Kazuki's left eye. At the blue ring. He studied it the way a doctor studies a test result they already know the answer to. "It's moving faster than it did in my timeline."
Kazuki crouched down. Stayed at eye level. "You're not a hunter."
"No."
"Malvorn sent you."
"Malvorn thinks he sent me." Dread shifted slightly. The black lightning arced harder for a moment, then settled. He winced. "My orders were to observe and report. Locate the host. Confirm the transformation timeline. Send data."
"But you didn't send it."
"No."
"Why?"
Dread looked at the ceiling of the maintenance corridor. A water pipe ran above them, condensation dripping at irregular intervals.
"Because I've seen where you end up," Dread said. "And I needed to know if this timeline was different enough to matter."
Kazuki said nothing. Waiting.
"My name is Darius," Dread said. It sounded like something he hadn't said out loud in a long time. Not a codename. An actual name. Like remembering he had been a person before he was an asset. "I'm from a timeline approximately sixty years ahead of yours. The Helix reached my world when I was eleven. By the time I was sixteen, half the continent was gone." He paused. "Malvorn recruited me because of what I could do. I didn't understand at the time what the lightning meant. What it was doing to me."
"Cellular Rot," Kazuki said.
Darius looked at him. A small, sad recognition. "You know about Renji."
"He was my trainer. He died."
Darius nodded slowly. "In my timeline he died earlier. He never got to finish what he was building." He looked at Kazuki's chest. At where the Core sat beneath the jacket. "The Mark II doesn't exist where I'm from. You're wearing something that should have taken another decade to design."
"Renji left blueprints."
Something passed across Darius's face. Grief, or something close to it, moving through and settling.
"Of course he did," Darius said quietly.
They sat in silence for a moment. The water pipe dripped.
"You've seen Kazuki Prime," Kazuki said. Not a question.
"Yes."
"Tell me."
Darius looked at him carefully. Measuring something. Then he spoke.
"He doesn't move like you do. You move like someone who learned speed — like a skill, like a language you got fluent in. He moves like speed is the only thing left." A pause. "In my timeline, I saw him once. Briefly. From a distance. Everyone who was with me ran. I stayed because I needed to understand what I was looking at."
"What were you looking at?"
Darius was quiet for a long moment.
"Someone who had outlived everything he loved," he said finally. "Every person. Every place. Every timeline he tried to protect. He didn't stop the world because he wanted to conquer it." Darius looked Kazuki directly in the eyes. "He stopped it because it kept ending. And he was tired of watching."
The corridor was very quiet.
Kazuki thought about Maya's vision. The stopped world. The comfort. He had assumed it was darkness. Cruelty. The end of a hero becoming something monstrous.
It had never occurred to him that it might be mourning.
"There's something in your timeline," Darius said. His voice had shifted — quieter, more careful. "Something that wasn't in mine. I've been here three weeks and I can feel it. I don't know what it is. But it changes the weight of things." He looked away. "I noticed it the first time I observed your team."
Kazuki waited.
Darius did not say who he was looking at when he felt it. He didn't need to. His eyes moved — briefly, involuntarily — to the direction of the garage.
In the direction of Aeva.
Kazuki filed it away silently.
Darius reached into the inside pocket of his cracked suit. He produced something small — a disc, flat and black, about the size of a coin, with a single hairline groove running across its center.
He held it out.
"I don't know what this does," Darius said. "I took it from Malvorn's intelligence archive before I came here. It was labeled as a variable in the Core transformation sequence. Something that appears in certain timelines and not others." He looked at it. "In every timeline where it appears, the outcome is different."
Kazuki took it. It was light. Cold.
The Core pulsed once when his fingers closed around it.
"Different how?" Kazuki asked.
Darius leaned his head back against the wall. The black lightning was more frequent now. His breathing had gotten slightly shallow.
"Different enough that I'm sitting in a maintenance corridor telling you this instead of sending Malvorn your coordinates," he said.
He closed his eyes.
"Go," Darius said. "Before the lightning gets loud enough for the scanners to pick up. I'll move locations."
Kazuki stood.
"Will you be alright?" he asked.
Darius smiled. It was tired and genuine and surprisingly warm for someone who looked like he was being slowly taken apart from the inside.
"Probably not," he said. "But that was true before I met you."
