The operative who stepped out had the specific bearing of someone whose training had included knowing when cover was no longer serving its purpose.
She said her name was Rael. She said she was working for the Solarian Union's intelligence division, which confirmed his read of the suppression cloak technology. She said she had been tasked with monitoring the Eternity Guild's operations since the Borealis Dominion trade mission had produced the boundary results that it had.
"The Solarian Union wants to know what you're doing," she said. "We've been watching long enough to have a significant amount of uncertainty about whether you're a threat to our interests or an asset."
"Which is it," he said.
"That depends on what you're doing," she said.
He considered her for a moment. The Fate's Eye's read: Tier 5, the same early-stage corruption integration he had been reading across institutional practitioners who had been operating in the ambient contaminated environments. Not deep. Not managed. Present.
"Are you aware," he said, "that the corruption in the atmospheric mana across the northern and western frontier regions has been integrated into your channels at low concentration?"
A pause.
"The medical division has been noting anomalous channel readings across field operatives for approximately eighteen months," she said carefully.
"The source was a deliberately planted contamination network running through the groundwater systems," he said. "We removed the primary source node three weeks ago from the northwestern corridor. The atmospheric clearing since then would be beginning to affect the ambient exposure levels, but the channel integration your practitioners have already accumulated won't resolve without direct intervention."
She was very still.
"I can address it," he said. "The extraction methodology requires direct contact with the practitioner's channels and approximately an hour per individual at the current integration depth. If your division wants that addressed for your field operatives, that's a conversation to have directly rather than through surveillance."
Another pause.
"What do you want in exchange," she said.
"Information," he said. "You've been watching operations across two worlds for at least six months. Tell me what you've seen that I haven't from the inside. What does the Solarian Union's perspective on the gate network deterioration look like?"
She looked at him for a long moment.
Then she said: "I need to make a call."
"Take your time," he said.
She did.
Twenty minutes later, she was still there, and the call had produced authorization for a preliminary information exchange at the level below what a formal treaty would require and above what could be called casual conversation.
He listened to what the Solarian Union's intelligence apparatus had been reading about the gate network deterioration from their side of the continental divide. Some of it confirmed what he already knew. Two pieces of it were data points he hadn't had.
He gave her the three-sentence summary of the manufacturing sector's scope that she could take back without it constituting a security risk to the operation.
"The Solarian Union's border practitioners," he said. "The ones with channel integration above a certain threshold — I can provide the extraction methodology to your medical division so your own practitioners can be trained in it. The technique is spatial law based and requires Tier 5 minimum practitioner skill to execute, but the methodology is documentable."
She received this and left.
He closed the three gates with the Catalyst devices, collected the cores, and went back to the Aurelian estate.
Sloane and Isolde were at the dining table when he arrived, the guild documentation stacked between them in the specific configuration of people who had been working through it systematically rather than performatively.
"The West Coast is clear," he said. "And I had a conversation with a Solarian intelligence operative that you both need to know about."
He walked them through it.
Sloane's response to the Solarian Union dimension was the military commander's assessment: a potential second channel for coordinating the gate clearance across the continental boundary, assuming the information exchange held. He had the specific quality of someone who spent decades on borders understanding that the practitioner on the other side of a line was frequently also dealing with the same problem from the other direction.
"House Vermillion funded the surveillance," Markus said. "Rael told me before she left. They're paying Solarian private contractors to maintain intelligence on the guild's operations — not to interfere, but to monitor. The attack framing they were operating under was contingent on information I don't believe they actually had."
"Meaning they didn't actually authorise an assassination," Isolde said.
"Meaning the contractor's brief was surveillance and the language she used was surveillance language until I stopped and confronted her," he said. "The 'proposition' framing was accurate — they wanted to negotiate, not fight."
"House Vermillion hired foreign intelligence to monitor us," Sloane said. "That's still a Covenant violation if it's directed at guild operations."
"It's in the legal grey area between intelligence gathering and operational interference," Markus said. "The Covenant protection clause covers direct asset seizure and aggressive deployment. Surveillance sits at the boundary."
"Which means the response should be political rather than direct," Isolde said.
"Yes," he said. "House Vermillion overextended by bringing the Solarian Union's intelligence division into an internal court dispute. That's the angle the Aurelian High Council's more independent factions will find useful."
Isolde looked at the court documents with the specific expression she used when legal architecture was being mapped.
"The court alchemist cabal," she said. "The archive lockdown. I've been assuming that was connected to Vermillion, but if Vermillion was operating at the surveillance level rather than the decision-making level—"
"The archive lockdown predates Vermillion's court filing," he said. "The timing is wrong for Vermillion to have ordered it. Someone else locked the archive."
Sloane set down his wine.
"The corruption in Caelen," Sloane said.
"Is early-stage," Markus said. "But someone put it there. Someone with access to the Aurelian elite's daily environment and the specific technical capability to introduce the contamination at the level it's been operating."
The three of them sat with this for a moment.
"The manufacturing sector's reach extended to Aethelgard through the aquifer network," Markus said. "If the Aurelian Empire's leyline network is the next significant target, the contamination infrastructure on this side would need to be established before the active push. We've been assuming the corruption arrived here organically through atmospheric spread."
"But if it was deliberately introduced," Isolde said, "someone is here who knows how to introduce it."
"Yes," he said.
He looked at the court documents.
"The archive lockdown is the first data point," he said. "Whatever's in those archives is something someone doesn't want us to read. That's where we start."
"How do we access a locked archive," Sloane said.
"We find out who locked it and why," he said. "Which is the same kind of work as the source node search. We follow the pattern back to the origin."
He poured himself tea from the pot that was still warm on the table.
"The three martial families," he said. "Isolde — what's the status of the initial contacts?"
She slid a summary document across the table.
He read it.
The second day's work had begun.
