The Arbitration Board's ruling on the archive access came through on the fourth day: the filing was valid, the Covenant clause applied, and Councillor Voss's objection was outside his jurisdictional authority to sustain. The archive would be accessible under supervised research conditions within the week.
The Grand Regent's invitation to the Celestial Horizon Auction arrived the same afternoon, through the formal protocol the guild registration had opened.
Markus looked at the two documents side by side.
The archive access resolved the intelligence problem. The auction offered something different: the direct observation of who in the Aurelian capital had what resources, and the opportunity to establish the guild's economic standing among the eastern elite in a way that the political filings alone couldn't accomplish.
"We attend," he said.
The Grand Obsidian Theater was built for exactly the kind of occasion it was hosting — the architecture and the acoustics designed around the specific function of a great many wealthy practitioners competing for limited supply. He noted, on the way in, that the anti-theft barriers were Tier 5 grade, which was appropriate for the price range the catalogue had indicated.
The Grand Regent's imperial box was floating, which was a status statement as much as a practical arrangement. The invitation specified the apex pavilion.
They were the last to arrive in the box before the auction's opening, which was deliberate. Markus had read enough diplomatic situations to understand that entering first in the formal space put you in the position of waiting, while entering last with appropriate timing put you in the position of being awaited.
The Grand Regent was a Tier 6 practitioner in his mid-hundreds — the primordial world's extended cultivation lifespan meaning that "mid-hundreds" had the visible bearing of someone in sustained active cultivation rather than decline. He stood when they entered, which was more than protocol required, which told Markus something about what the guild registration and the past week's legal filings had communicated to his office.
"Matriarch Aurelian," he said, with the specific warmth of someone acknowledging a name they had been briefed on by people who told him it mattered. "Patriarch Blackwell. And the guild master himself."
Isolde received the greeting with the composed warmth of someone who had been navigating this specific category of formal recognition for longer than the Regent had been ruling.
They sat. The opening lots were being prepared below.
He waited until the second lot had completed before raising the currency exchange question.
Not as a negotiation opener — as a practical observation. The catalogue had made the local currency requirements clear, and the Eternity Guild's asset holdings were not in the form of thousands of standard mana stone crates.
"We have a liquidity question," he said. "Our resources are primordial-origin materials rather than the standard imperial mana stone. The exchange rate between the two in your treasury's current assessment — do you have a working figure?"
The Grand Regent looked at him with the attention of someone who had spent decades in a role that required him to identify when a conversation had just become interesting.
"The treasury's last assessment was theoretical," the Regent said carefully. "No significant volume of primordial-origin material has moved through the Aurelian market in the current era."
"Then you don't have a working rate," Markus said. "Which creates a problem for both of us if we want to participate tonight."
"Unless we establish one," the Regent said.
"Yes," Markus said.
The proposal was straightforward: the Eternity Guild would provide medium-grade primordial mana stones at a fixed exchange rate against the imperial standard, the treasury guaranteeing the conversion. The rate he proposed — 1:800 — was conservative relative to what he believed the actual value was, which was the appropriate starting position for an exchange rate that would be revised by market discovery.
The Regent thought about this for approximately fifteen seconds, which was the time required for someone at his level to understand the arithmetic.
"The treasury would require a floor deposit," the Regent said. "To validate the exchange before we extend credit against it."
"Of course," Markus said.
He produced from the dimensional inventory three medium-grade primordial mana stones — the specific specimens from the Tier 4 beast cores that had the highest density of the batch. He placed them on the box's presentation surface.
The Regent's mana sense registered them before he physically reached for one. The way he held it afterward was the specific way a practitioner held something that had recalibrated their sense of what was possible.
"The floor deposit is sufficient," the Regent said, after a moment.
"Good," Markus said. "We'd like to list some materials as well."
The floor manager's professional composure was tested by the primordial botanical specimens more than by anything she had apparently processed before.
The Ashen Lotus specimens — four of them, in their stasis containers — were the primary listing. The pre-differentiation substrate these specimens carried produced the specific atmospheric response that high-density novel materials always produced in a room full of practitioners: the automatic, involuntary read of something the mana sense didn't have a category for.
The appraiser's valuation process took twenty minutes. He was methodical in the way of someone who understood that a rushed valuation of something this unusual would embarrass his professional standing.
His final assessment, delivered quietly in the floating box: "The botanical signatures are pre-fracture substrate in a stable biological form. I have no direct comparable for the valuation. My methodology suggests a floor of 400,000 imperial stones per specimen based on density alone, but the ceiling is genuinely undefined."
"The floor is acceptable," Markus said.
The second listing was the Obsidian Mastodon core from the frontier sector — the one he had brought back for Isolde's analysis and that she had already extracted what she needed from. A Tier 4 primordial core, intact, unrefined. A rarity in the Aurelian capital's market, the appraiser confirmed.
The floor manager scheduled both listings for the auction's later session.
The auction ran for three hours.
He bid on three items from the main catalogue — specifically the archive-adjacent materials he had identified in the pre-auction catalogue review. A set of first-era leyline survey tools, the kind of precision instruments that the pre-fracture era had produced before the technology was lost. A bound collection of Aurelian law documentation from the period immediately preceding the current era.
The first he purchased because the leyline survey tools complemented the household records Isolde had been working through. The second because it predated Councillor Voss's thirty-year tenure and would tell him what the Aurelian administrative structure had looked like before whatever had changed.
He noted who bid against him on the law documentation and how hard they pushed before conceding.
The competitive bidder was not associated with any of the obvious factions. He filed this.
The Ashen Lotus specimens drove the room to a different kind of attention.
Not spectacle — the specific absorbed silence of practitioners encountering the upper range of what they understood was possible. The bidding ran for twenty minutes on the first specimen, the floor manager's auction discipline the only thing preventing it from becoming something else entirely.
Final price on the first specimen: 1.1 million imperial stones.
The second: 1.3 million.
Sloane, watching the bidding, said nothing but had the specific quality he had when something was going exactly as it should.
The Obsidian Mastodon core closed at 620,000.
At the auction's conclusion, the currency exchange had been established, the archive access ruling was in hand, and the Aurelian capital's practitioner community had a significantly updated understanding of what the Eternity Guild had access to.
On the way out, the Regent paused them.
"The exchange rate," he said. "The treasury's position, after this evening, is that 1:800 undervalues the primordial materials considerably. We would prefer to revise upward before the next transaction."
"We can discuss the revision," Markus said. "At your convenience."
"Tomorrow morning," the Regent said. "My office."
"Tomorrow morning," Markus confirmed.
They left.
The archive access was in five days. The martial family contacts were consolidating. The currency exchange was established. The survey tools and the documentation he had purchased were in the inventory.
He went back to the estate and spent the remaining hours of the evening with the household records and the leyline construction documentation that Isolde had found in the original builder's files.
The archive would either confirm what those files suggested or tell him something the files had missed.
Either way, he would know more in five days than he knew tonight.
That was sufficient.
He read.
