The Platinum-level audit request produced the meeting in two days rather than three, which told him something about how the syndicate administrators had been monitoring the guild's access activity since the Millennium Rainbow.
The quarterly tribute review session convened in the Sovereign Guild's restricted conference suite — a closed-environment space with the anti-scrying and acoustic isolation that the guild's high-tier administrative meetings maintained as standard. Seventeen of the twenty-two deep-integration individuals Rosanne's map had flagged were present. Of the forty-seven total early-integration practitioners in the upper-ring network, thirty-one had operational reasons to attend a Platinum-level tributary audit.
He did not explain what the meeting was actually for.
The atmospheric dispersal compound was Isolde's engineering: a formulation that bonded to the ambient mana in an enclosed space and interacted with the specific corruption frequency on contact. Detectable only by a practitioner actively scanning for the specific interaction, which none of the syndicate administrators were doing.
He released it through the ventilation matrix at the room's first break period.
The early-integration cases would have the surface-layer corruption's mana signature disrupted over the following four hours. Combined with the ongoing atmospheric purification from the Millennium Rainbow's lasting effects, they would clear over the following weeks without any further intervention.
He ran the actual audit simultaneously, because the actual audit was also necessary.
The tribute records for the past three years showed the specific pattern the archive's historical data had predicted: the modified leyline nodes had been redirecting a portion of the tribute's mana content in the same direction as the gate harvesting operation. Not the same mechanism — the gate harvesting had been external extraction, this was internal redirection — but the same endpoint. The citadel.
He documented this and sent it to Valerian's office before the meeting concluded.
The deep-integration cases required the individual approach.
Over two days.
He did not find seventeen. He found fifteen — two of the flagged individuals had left the capital for regional postings in the preceding week, which he noted as either coincidence or evidence that someone had become aware of the audit and moved assets accordingly.
Fifteen extractions. An hour each for the more deeply integrated cases, forty minutes for the ones whose integration was deep but not at the Voss level.
He kept the documentation that Isolde had asked for: the channel architecture before and after, the corruption's node structure, the specific depth and character of the integration in each case. Research material for the counter-compound's refinement.
Thirteen of fifteen accepted the explanation he gave them: a corruption in the leyline network had been affecting practitioners in proximity to certain nodes, he had developed the extraction methodology, was she or he willing to have the channel work done. Two refused. He did not press them. Their names went into the documentation with the note that voluntary refusal was not clinical justification for proceeding without consent.
One of the thirteen, after the extraction had completed and she had sat for a few minutes with the specific quality of someone whose internal environment had just changed in a way she could feel but hadn't understood was possible, looked at him and said: "How long has it been there?"
"Approximately eighteen months for your case," he said.
She looked at the window.
"The tribute meetings," she said. "The decisions we made. Were they—"
"The corruption doesn't control," he said. "It influences. The decisions were yours. The influence was real, but it was working on your existing judgment rather than replacing it."
She sat with this.
"That's not as reassuring as it sounds," she said.
"No," he agreed. "I know."
Councillor Voss was the last.
He had saved him for last because the deep-integration cases required the most careful reading before the extraction began, and the Voss case was the most advanced integration he had read since Saylor at the two-year mark.
The extraction required the full hour. The Fate's Eye held the architecture map throughout, the spatial law addressing each node cluster in the sequence the map indicated rather than in sequence of convenience. The corruption's response to the extraction was the most significant defensive counter he had encountered in any of the fifteen: the integration was old enough to have developed pathways that tried to re-establish when disrupted.
He was faster.
When it was complete, Councillor Voss was in the specific state of the immediate post-extraction period: conscious, aware, and in the process of understanding what had just happened.
"The archive lockdown," Markus said. Not as an accusation. As the accounting.
Voss looked at him.
"I ordered it," Voss said.
"I know," Markus said. "What did you understand about why you were ordering it at the time?"
Voss thought about this.
"I believed I was protecting the archive from misuse," he said. "The Aurelian lineage's documentation was sensitive and the custodianship arrangement with House Vermillion had created access vulnerabilities." He paused. "I believed that."
"The belief was not entirely false," Markus said. "The reasoning was real. The conclusion it drove you to was the one the corruption was producing."
Voss sat with this.
"The leyline modifications," Markus said. "You didn't order those."
"No," Voss said. "I don't know who did. I know I failed to flag anomalies in the network reports for approximately two years. I believed I was exercising discretion. I believed the anomalies were within normal variance."
He noted the timeline alignment between the archive lockdown and the period of anomaly non-reporting and filed it. The person who had actually modified the leyline nodes had worked during the window Voss's corrupted judgment had produced.
"The node modifications," Markus said. "Whoever did them needed access to the leyline maintenance schedule and the technical specifications of each node. Who has that access?"
Voss gave him four names.
He sent them to the restricted archive team for cross-referencing with the modification timeline.
"The academy," Voss said, as Markus was preparing to leave.
Markus looked back.
"The Aurelian family's academy," Voss said. "I would have obstructed it. Six months ago, I would have found reasons and filed them." He looked at his hands. "I want you to know I know that."
"The obstruction didn't happen," Markus said.
"No," Voss agreed. "It didn't."
He left.
The team was at the estate when he returned, and the post-extraction documentation was on the table, and Rosanne had been running the intelligence picture on the citadel approach while the extraction work had been occupying him.
She looked at him when he came in.
"The archive cross-reference came back," she said. "One of the four names Voss gave you. A junior archivist who resigned fourteen months ago. Traced to the manufacturing sector's territory."
"An agent," he said.
"Working from inside the Aurelian administrative structure," she said. "Which is how the leyline modifications were made without triggering the standard anomaly detection."
He looked at the citadel intelligence map she had been building.
"The agent is gone," he said. "The nodes are documented. The extraction is complete. What does the citadel picture say?"
She laid it out.
Thirty years of tribute redirection, gate harvesting, and leyline modification had been feeding a construction project in the mountain range north of Aethelgard. The construction's purpose, derived from the material composition in the tribute records: a permanent bridge. Not the temporary gate structure that Vorash's harvesting operation used for extraction. A permanent, high-capacity dimensional conduit between the primordial world and the framework side.
Large enough for Vorash himself to cross.
"He's been stranded here since before the mana event," Rosanne said. "He has the manufacturing sector, the territory, the tribute network. But he's been building the one thing he doesn't have: a way through."
"And the acceleration," Markus said. "He knows the Trench gate was cleared. He knows the source node is gone. He knows someone has been reading his operation."
"Which means the construction timeline is no longer thirty years," Rosanne said. "It's whatever he has left."
"How far along," he said.
She pointed to the tribute record analysis. "Based on the material volume delivered to the citadel coordinate over thirty years, and comparing it to the manufacturing sector's entity production rate as a reference for what his construction speed looks like at scale — seventy to eighty percent complete."
He looked at this for a moment.
"He doesn't need to finish it," he said. "He needs it functional enough to cross. At seventy percent, a permanent bridge might be passable by someone at his cultivation level."
"Which means we can't wait," she said.
"No," he said.
He looked at the team. All four of them, looking back.
"We leave at first light," he said. "The full picture. We go to the citadel, we read what the construction actually is, and we determine whether the Catalyst can address a construction of this scale or whether we need a different approach."
"And if we need a different approach," Jessica said.
"Then we figure out the different approach when we're there and I've read it with the Fate's Eye," he said. "I'm not going to plan for something I haven't seen yet."
Rosanne nodded once. The commander's acknowledgment.
"First light," she said.
He went to the Time law tome.
The fourth page was still beyond his current comprehension. But the fragment's interval property had given him something he hadn't had before: if the temporal anchor network recorded how long the framework had been in place at each anchor point, and if the citadel's construction was designed to breach the framework's boundary, the anchors nearest to the citadel would be showing stress signatures consistent with the breach's projected location.
He knew where to look.
He read until he was ready to sleep, and then he slept, and in the morning the five of them went north.
