Ada could talk now. That was the first thing. The chains had taken her voice along with everything else, and getting it back seemed to cost her something — every word came slow, unwrapped, like she was checking to see if it still fit.
"Three worlds," she said, sitting on the steps of the throne that had held her. "You're the first one to look at that trap and find a door in the floor." She almost smiled. "I stopped hoping someone would around the second Integration. Hope was heavier than the chains."
Priya had brought her water. Ada drank it like a person remembering how. Behind us, the Auditor stayed bound and silent, its grey text frozen mid-scroll, and I tried not to look at it, because it had emptied my whole toolbox eleven minutes ago and I could still feel the six holes where my skills used to be.
"They're gone," I said. "Everything I copied. It audited all of it. I'm back to one skill and a monster noise."
"I know." Ada looked at me, and now the almost-smile was gone, replaced by something older and more useful. "Do you understand why it could take them?"
"Because they were on the ledger. Licensed skills. Copied off licensed people."
"Because they were borrowed," she said. "Everything you took, you took at one percent of someone else's ceiling. You've been building yourself out of loans, Leo. And an Auditor can always call in a loan." She stood, slow, and crossed to me, and put a hand — thin, cold, real — against my chest, over the empty rack. "That's the leash. Not the number. The number's just the lock. The leash is that they made your whole class derivative. One percent of someone else, forever, so you'd never have a single thing that was yours — nothing the ledger couldn't reach in and delete."
"So how do I—"
"You already did it once and didn't notice." She tapped my chest. "The monster call. You didn't copy that off a licensed class. You took it off a thing the ledger doesn't track, and ground it up yourself, in the dark, at six in the morning, because no one told you it was worthless — you decided it was worth something. That one, the Auditor couldn't touch. That one's yours."
The whole shape of it turned over in my head, and clicked, the way the plan had clicked on the stairs on the first night.
Everyone had told me the worst thing about my class was the one percent. It wasn't. The one percent was the part I could grind. The worst thing — the real leash — was that I'd been trained to shop only from the authorized shelves. To copy the Flame Wardens and the Shadow Tamers, the licensed, the tracked, the revocable. To build myself entirely out of things someone else could reach in and un-give.
And the whole world outside the ledger — the monsters, the Thresholds, the caretakers' own chains, the Root itself — was full of things no Auditor had ever bothered to list.
"Ada," I said slowly. "The Root. The thing you copied at the center. Is it—"
"On the ledger?" She laughed, and it was a terrible, wonderful sound, the laugh of someone who has been waiting three worlds to say this to the right person. "Leo. The Root is the thing the ledger is written on. It's the one skill in all of creation that no Auditor can ever revoke, because revoking it would delete the pen." She stepped back. "That's why they couldn't kill me. That's why they chained a whole class instead. One percent of the Root is one percent of a thing that is yours the second you take it, forever, off every list there is."
[Threshold — Tier 2: CLEARED.]Second local Threshold resolved. Anchor released.The System notes that the Descent is now collapsing, because its core is gone, and you are all still inside it.The System suggests you run. The System will even, this once, tell you which way.
The black glass began to crack, high up, and cold light poured through. Ada didn't move toward the exit. I looked at her and understood, the way I understand things now, at the percent.
"You're not coming," I said.
"Three worlds awake, Leo. I'm tired in a way that doesn't have a percent." She pressed something into my hand — not a skill, the System didn't click, just her cold thin fingers folding mine closed. "I can't make the climb again. But I can give you the map. The center of your city. The Root. It's real, it's here, and it's the only thing they can never take back once you hold it." Her eyes were bright. "Copy it. Break the leash. Not just yours — all of them. Every Copyist they chain after you. End the trap you almost walked into."
The Descent came apart around us in falling sheets of light. Priya grabbed my sleeve. Sprinkles was already at the stairs.
The last I saw of Ada, she was sitting back down on the empty throne, in the falling light, with her face turned up — free, finally, and choosing the quiet — and she was, at long last, not hoping for anything at all.
