Day 60 was twenty-two days away.
"The relay station locations," I said.
She named them. I logged them — three military installations in different sectors, all legitimate in terms of their primary function, all hosting what their commanding officers thought was standard communications infrastructure. None of them knew.
"Why are you giving me this," I said.
She looked at the data cylinder. "Because I joined a coordination task force," she said. "Not a colonization operation. The distinction matters to me." She looked up. "And because you told me the truth about the sabotage when you didn't have to, and I've been in enough situations where people lied to me for operational reasons to be able to tell the difference."
"What do you need from me," I said.
"The same thing I gave you," she said. "Advance notice. If I identify a threat to the task force's actual mission — the coordination assistance mission, not the colonization backstory — I want to know about it before it becomes a crisis." She paused. "And I want to know what you're planning to do about the relay stations, because if you do something visible it creates a problem for the task force members who don't know what they're actually part of."
This was a reasonable ask. It was also the ask of someone who had decided to operate as an ally rather than a neutral party, which was a commitment with consequences she had clearly already accepted.
"I'll neutralize the relay stations quietly," I said. "Earth-aspect structural work — I can degrade the receiver components without triggering anything that looks like active interference. It'll read as standard equipment degradation." I paused. "The logistics coordinator. The one who actually knows what the relay is."
"Is not in this sector," she said. "They're coordinating from a different region. I don't have their current location."
"I'll need it eventually."
"I know." She picked up the data cylinder. "The mana key." She pressed her hand to it — a brief contact, a specific mana signature. The cylinder's sealing rune disengaged. "That's all I have on the operation. The rest I'll share as I get it."
She turned to leave. Then stopped.
"The 15% residual," she said. "Is there a way to eliminate it."
"Not from outside," I said. "It's quarantined in a partition that's architecturally isolated. I can't access it to degrade it further without reopening the partition, which would risk partial release. The safest approach is to make it irrelevant — prevent the relay from receiving the signal at threshold." I paused. "Which means neutralizing the stations before Day 60."
"You have twenty-two days."
"I know," I said.
She left. I opened the data cylinder and spent the next three hours reading.
**Earth: Days 39–45**
The Tier 3 to Tier 4 transition had been on the timeline since Day 1 on Avulum, when Vasir had written it on a wall chart with the calm specificity of someone describing a surgery that might kill the patient but was necessary anyway.
Vasir had planned it for after the sprint, after the Sanctification, after the transit — the assumption being that I would land on Earth at Tier 3, consolidate, and begin the compression process once I had stable operating conditions.
*Stable operating conditions* had turned out to mean: three relay stations that needed neutralizing in three weeks, forty-three active sensitives in daily support, a Maw Gate anchor forty meters underwater that I couldn't reach yet, a Tower agent providing me intelligence in exchange for advance notice, and my mother cross-referencing the civilian registry with Day 1-10 medical records.
This was, technically, stable relative to the alternatives.
The compression works like this: Tier 3 capacity is 2,000-2,500 mana units, held at a specific density. Tier 4 capacity is 4,000-5,000 units at higher density. The transition requires compressing the existing core to the point of structural failure and then stabilizing it at the new density before the architecture collapses.
Failure rate among Tower mages: forty percent under optimal conditions.
Optimal conditions were not what I had.
What I had instead: eight elemental channels providing multiple compression vectors simultaneously, a Blank Slate architecture that the Architect had specifically designed to survive pressures that killed conventionally structured mages, and the accumulated foundation knowledge that made each element's contribution to the compression process comprehensible rather than blind.
The Architect's notes on the Tier 4 transition were specific. The Dead Zone was going to be the problem. The obsidian shoulder was structurally dense and mana-inert — it didn't participate in the compression process. That meant the compression force was distributed unevenly, which meant the structural bracing architecture needed to compensate.
*The truss system,* the Architect had written in the message that unlocked at this milestone. *The Dead Zone is not a weakness in the compression. It is the anchor point for the truss. Compress toward it, not away from it. A structure that has learned to hold around a void is stronger than one that has never failed.*
I spent four days before starting the compression running the structural calculations. Not because I doubted the Architect — he had been right about everything — but because I wanted to understand the why before I committed to the how. The how, if it went wrong, was not recoverable.
The calculation confirmed it. The Dead Zone, surrounded by the Earth-lattice's structural memory and the Air-aspect bypass circuits and the Water-aspect cooling channels, was the most stable point in my architecture. Every high-density element had been built around it. The truss system the Architect had described was already there — I'd been building it since the Behemoth core on Day 44 of Avulum without knowing that was what I was doing.
I began the compression on Day 39.
