The conversation Kervath had been working toward for two weeks happened on a Thursday.
Aion was cooling down after drills, eating — Darin had developed the habit of bringing extra food to training because Aion burned through a significant amount of it after high-output sessions, which everyone had noticed and nobody had commented on. He was working through a grain cake from the vendor near the yard's east entrance, sitting on the floor with his back against the wall, when Kervath came and sat down across from him.
Not on the trough. On the floor.
Kervath sat on surfaces. Not floors. This was the first time in three weeks of training sessions that Aion had seen him choose the floor, and he noted it without reacting, the same way he noted most things.
"Your speed," Kervath said.
"What about it."
"Talk me through it. Not the techniques, the experience of it."
Aion took a bite. Chewed. Thought about how to answer that honestly.
"When it's active at maximum," he said, "the world stops looking like it moves. Everything around me, people, objects, air currents, they go still. Not actually still. Just slow enough that still is the most accurate word for how they look." He studied the grain cake. "It's like the gap between me and everything else becomes a different kind of time."
"How long can you hold maximum?"
"Five minutes, maybe six. It varies." He thought about how to describe what came after that. "After that it's like I've been awake for a week without sleeping, except the week happened in those five minutes and now I have to carry all of it in my body at once. Everything that should have been spread across seven days lands at the same time."
"So the cost is real."
"The cost is very real. That's why I keep it off." He looked at Kervath. "Running at normal human speed is boring. But boring is sustainable. I can run at boring all day."
In the corner, Darin had his tablet but wasn't writing. Nera had her Thread-sight running in narrow-focus mode, the tight precise setting she used when tracking something specific. Both of them were sitting still in the particular way people sat still when a conversation was happening that they didn't want to interrupt — present, attentive, letting the room be what it needed to be.
Kervath leaned forward slightly. "You said boring."
"I said boring."
"When you run at maximum, when the world goes still, what does it feel like?"
Aion considered this. It wasn't a question he'd been asked before in that form. Nobody had ever asked him about the feeling of it, only the function. "Correct," he said finally. "It feels correct. Like everything else is running at the wrong speed and maximum is the right one."
"The rest of the time?"
"The rest of the time," he said, "is me waiting for the world to catch up with something I've already thought."
Kervath pressed his thumb against the stone floor between them. That searching gesture. Working toward something.
"I need to tell you something about your speed that you may not fully know yet. And I need you to understand that what I'm going to say isn't an insult."
"Hard setup," Aion said.
"Your speed isn't normal."
"I know. That's the vein—"
"Not in the way you mean." Kervath held up a hand. "I've worked alongside Legs-type vein bearers at every tier the institutional system produces. Fast ones. The kind that move at speeds a normal eye can't follow. The kind that drilled techniques for years until those techniques stopped looking like techniques and started looking like physics being rewritten." He paused. "Every single one of them had the same thing in common. Their speed was physical. More force in the legs, more velocity out. A better version of running. Faster, stronger, more efficient. But still running."
"That's what I do."
"That's what you think you do." He looked at the stone between them. "What I've been watching for three weeks, and what Nera has been watching for three months — what you do at maximum isn't a better version of running. It's something that uses running as its delivery mechanism for something else."
Silence settled into the yard like weight.
Aion looked at his hands.
"The ground cooperates," Kervath said. "Not always, not dramatically, but consistently. The footing is better than the terrain should allow. Opponents are slightly more out of position than they should be. The angle you need is slightly more available than the physics of the situation should make it. At maximum. Always at maximum." He pressed his thumb down. "Speed doesn't do that. Speed just moves faster. What you have at maximum, at those moments — it's as though the situation is being arranged around you. i think it's the energy you release."
"You're saying my vein does something else," he said.
"I'm saying there's something in how your vein expresses that isn't standard Legs-type expression." Kervath held his gaze. "I don't know what it is. I have a partial theory I'm not ready to say yet, saying a partial theory before it's confirmed is how you contaminate the evidence. But Nera has fifty-four data points and I have twenty-two years of field observation, and what I can say is this: what you are is not what I've seen before."
Aion was quiet for a moment.
"My vein has been active since I was six," he said.
"I know."
"I've been running the same drills, the same techniques, the same routes. For years. I know my vein. I know what it does. I know how it feels when it's working and how it feels when it's about to fail and how long I can push it before the cost hits."
"I know," Kervath said again.
"So tell me what you think I'm missing. Because I've been using this thing every day for a decade and nobody has ever described it the way you're describing it."
Kervath looked at him for a long moment.
"Nobody ever watched you the way I watched you," he said. "Most people who see you move see the outcome. They see fast, they see effective, they're impressed or alarmed and they move on." He paused. "I watched the moment just before the outcome. For twenty-two years I've been watching moments just before outcomes."
Nera's pen dropped from her fingers and rolled one inch across the stone.
Darin had not moved for two minutes. He was looking at the wall, at the crack pattern he'd spent four years building, the evidence of decisions.
Aion looked at Kervath's thumb on the floor between them. At the small depression it had made, searching for something solid.
"What does your partial theory say," he said.
"My partial theory says you are not a normal Legs-type bearer." Kervath held his gaze steady. "It says that what appears in your residue at maximum, what Nera can't classify, what I can't name, it belongs to another category, and i think mainly your vein gives you more than one."
The Lumen-Pulse came through the yard's high windows. Amber. Gone.
Aion sat on the floor of the processing yard where he'd trained since he was six years old and thought about ten years of that time.
He didn't say anything.
He filed it.
He finished the grain cake.
