He found Saylor's position in the spatial map before he consciously looked for it.
That was how it worked with signatures he had been tracking for two years: they registered automatically, the Fate's Eye filing them in the ambient read the same way it filed anything that had been flagged as relevant long enough to become a passive category.
Saylor was in the standing section at the arena's far edge, among the returning students who had come to watch the entrance trials. He was alone in the specific way that a person in a crowd was alone when the space around them had expanded without their choosing it — people finding reasons to stand slightly further away, the social field that the corruption's expression created operating below the threshold of conscious detection but above the threshold of felt discomfort.
The Fate's Eye's read was the same as it had been at the tournament, and worse.
Not worse in the categorical sense — the corruption had not progressed to a stage he would classify differently from what he had classified it as then. Worse in the degree. The structural dark that had been a property of Saylor's aura at the tournament had been integrating for two years, which was the specific process that things integrated into a person over time when they were not addressed. It was more thoroughly his now than it had been then.
The Poison element, which had been his primary affinity at the tournament, was not what the Fate's Eye was reading as his primary affinity now. Whatever the dark was — the thing that had moved into the space grief had opened — it had been present long enough and at sufficient concentration that it had begun to overwrite rather than simply coexist.
He looked at this for a moment.
He thought about a conversation he needed to have.
The new students were being led toward the residential spires by Candle, who moved through the column with the specific efficiency of someone who had performed this function dozens of times and had refined the route and the pacing to the exact formula that got three hundred and fifty students to their dormitory assignments in the minimum number of steps.
Three hundred and fifty. His cohort had been three hundred.
"Fifty more qualified candidates than two years ago," he said, to Elena, who was standing beside him at the arena's edge watching the procession.
"The Ghost Sense programme's first full cycle produced measurable improvements in the trial scores across the upper third of the intake range," Elena said. "The practitioners who came through the schools that implemented the Stage 1 and 2 curriculum additions performed better on the agility and combat trials specifically." She watched the last of the students disappear under the dormitory arches. "Whether they maintain the promise the trials showed is the part we don't know yet."
"They will," he said. "The sensory architecture doesn't degrade once it's built. The question is whether they have the temperament to develop it."
Elena looked at him briefly. "Not every practitioner does," she said. "Which is also data."
"Yes," he agreed.
He watched the last of the column disappear.
"I need a private word," he said.
Elena's office settled into its familiar sandalwood quality as the earthen lotus deposited them.
Lucy was on the couch, which was where Lucy was. She established her opinion about his lap within seconds, which he accommodated.
He spent a moment with the cat's warmth against his hand and organised what he needed to say in the order that made it clearest.
"Saylor Vane," he said.
Elena's expression moved slightly.
"I've been reading his aura at every opportunity since the tournament," he said. "The dark is no longer a distinct presence that coexists with his primary affinity. It's been integrating. The Poison element is still there but it's secondary now. What's primary is something I don't have a classification for, but the Fate's Eye reads it as actively consuming rather than passively expressing."
"Elder Isaac has been monitoring him," Elena said. "Discreetly. The behavioural profile confirms what you're describing — he's been increasingly isolated, his academic performance erratic, and there have been reports from the dormitory staff about episodes that are consistent with the mana state you're describing asserting control over him in ways he may not be fully aware of."
"He's losing the distinction between himself and the corruption," Markus said.
"That's Isaac's assessment," she said. "Not yet total. But the direction is clear."
He looked at Lucy.
He had thought about this conversation for a long time — the specific shape of what was possible here, and what the options were, and what each of them cost.
"I want to be assigned a joint mission with him," he said. "A portal excursion, the two of us, external rather than the palace facility. The spatial domain at 100% spatial law comprehension can read the corruption's architecture with a resolution I didn't have at the tournament. There's a possibility — I want to be clear that I don't know if it's more than a possibility — that I can apply the spatial law's interaction with the corruption's mana structure to address it at the root. The same category of mechanism as the Sovereign Catalyst synthesis, but applied to a living practitioner."
Elena was quiet.
"The conditions would need to be right," he said. "He would need to be in a state where the corruption was actively expressing, which gives me the clearest read on its architecture. The excursion context would provide that. And we would need to be isolated enough that if the extraction attempt is successful, the corruption's discharge doesn't reach other students."
"And if it isn't successful," Elena said.
He held this.
"Then we've established that the corruption is past the point of extraction, which is information that changes what the options are." He looked at her directly. "I don't want to have that conversation now. I want to try the extraction first, with full documentation of everything the attempt produces, and arrive at the other conversation only if the evidence requires it."
Elena was quiet for a longer moment.
"Celeste's warning," he said. "The one at Illinois City. About the line between necessary force and desensitisation. I've been carrying it since the barracks. This is the situation it was about." He did not look away from Elena. "I am not casually proposing what you think I'm proposing. I'm proposing the extraction attempt, documented and monitored, with the acknowledgment that a harder conversation exists if the extraction fails. But it doesn't start there."
Elena's expression had the weight of someone who had been managing complex situations involving students for a very long time and had not stopped finding them heavy.
"Isaac's monitoring can be reconfigured to support the extraction attempt," she said. "He has the closest read on Saylor's current architecture after two years of watching him." She looked at Markus. "If I authorise this, it's under full documentation protocol — Isaac on the remote monitoring feed, my office briefed at every stage, and the attempt ends at any point the monitoring identifies a threshold I'm not comfortable with. You're not going into that portal without a clear abort condition."
"Agreed," he said.
"And Markus." She held his gaze. "The moment you're in that portal, you're responsible for Saylor's wellbeing in the same way you're responsible for your own. Not as a target. As a student whose situation has become dangerous through no entirely simple accounting of fault." Her voice was level. "He's not what Sylas was. He was a boy who lost someone and made a series of choices with diminishing clarity. Keep that in front of you."
"I know who he is," Markus said.
"I know you do," she said. "I'm saying it so you have a version of it that came from me."
He sat with Lucy's weight on his lap and looked at the mana-lamps on Elena's desk.
"When can we schedule it," he said.
"Give me a week to coordinate with Isaac and review the monitoring configuration," she said. "The semester has started. We have time to do this correctly rather than quickly."
"A week," he said.
He picked up Lucy, relocated her to the couch cushion beside him, and stood.
"Thank you," he said.
"Don't thank me yet," Elena said. "We haven't succeeded at anything."
"No," he agreed. "But we're going to try."
He left the office and went to find the corridor where Rosalind would be coming out of the medical assessment.
He had training notes to discuss.
And he had the weight of the other conversation, which he was going to carry correctly rather than set down.
Celeste had told him to keep the weight.
He did.
