He did not sleep well.

This was not new — sleep had been unreliable since his mother's death, the nights either too long or too fractured, the body present in the bed while the mind continued its accountancy of the day's events. But the quality of this particular sleeplessness was different from what he had been living with. The previous months' insomnia had been heavy, depressive, the body refusing rest not from agitation but from a kind of exhausted inertia, as if even the physiological process of sleep required more investment than he could spare.

Tonight he was not inert. Tonight his mind was moving.

He lay in the dark and thought about Resonance.

Specifically, he thought about what Aurelia had done at the tavern — the mechanism of it, the technical specifics of how a Weave-Dancer's Resonance output could function as a structural support for a collapsing Cadence Manipulation framework. He had read about this in the historical texts: accounts of battlefield applications, where Weave-Dancers had been used to stabilize injured Spell-Violinists who could no longer maintain their own Resonance coherence. A wartime technique, lost with the tribes that had practiced it, described in terms that he had at the time found somewhat mystical and imprecise.

It was not imprecise. It was exactly what he had experienced. And it required, he understood now, not just technical skill but a specific kind of attention — the ability to read another Cadence Wielder's Resonance state with enough accuracy to determine what kind of support was needed and produce it without disrupting the existing framework further.

She had done this in a tavern, in the middle of a performance, without warning, at a level of precision that suggested it was not the first time she had done something like it.

He turned over in the dark and thought about that.

He also thought about the orange of her dress at the edge of his peripheral vision when the panic was loudest. Which was a different kind of thought, and one he was less certain what to do with.

In the morning he went to the cathedral earlier than usual.

She was there, as always, in the middle of her morning practice. He had known, since the second week, that she came here in the early hours as well as the afternoon sessions — she had mentioned it in passing once, the six o'clock footwork drilling she had committed to, and he had not thought about it much at the time. But standing in the cathedral entrance now, watching her move through the early morning light that came through the east gaps at an angle completely different from the afternoon light he knew, he was aware of a version of this place and this person he had not previously had access to.

She was doing something small. Not the competition piece. A sequence he had seen fragments of before — the one she transitioned out of when he arrived for their sessions, the personal-looking practice she kept separate from the shared work. In the early morning light, with no audience and no purpose other than itself, it looked different from the competition choreography. Less structured, more internal. The kind of movement that came from necessity rather than performance.

The cherry trees were responding to it quietly, not with the active luminescent drift of the afternoon sessions but with a slower, more continuous pulse — a background hum of Resonance that felt like the trees were breathing alongside her rather than reacting to her.

He stood and watched until she reached a natural stopping point.

She turned without apparent surprise. You are early.

I wanted to ask you something.

She picked up her water flask and drank from it — the ma luc preparation, the smell of it faintly mineral in the cool morning air. He watched the number of swallows: three.

Ask, she said.

Weave-Dancing, he said. The specific technique you used last night — the Resonance support. Where did you learn it?

She lowered the flask and looked at him. It is not really a technique, she said. It is more — a way of relating to another person's Resonance. You learn to read what it needs rather than what you want to give it.

That is a description of the principle, he said. I am asking about the source. Who taught you.

She was quiet for a moment. A beat too long for a simple answer to a simple question.

My mother, she said at last. Among others.

Your mother was a Weave-Dancer.

Yes.

And she learned it from —

From her mother, she said. It is a lineage practice. It does not transmit well outside the lineage. She said it with the particular smoothness he had learned to associate with the closing of a door. He noted the smoothness and the specific vocabulary she had used — lineage practice, not family tradition, not something passed down. Lineage. A technical term. The kind used in ethnographic and historical texts to describe the transmission of knowledge in organized cultural systems.

He asked the next question carefully.

The cathedral, he said. You knew it before you came to Oakhaven. You navigated the interior on the first day as if you had a map of it. The Nightbloom Cherry trees — you know their properties in ways that go beyond casual familiarity. The movement pattern you were practicing this morning — I have seen fragments of it in the restricted archives at the Academy. It is listed as a ceremonial movement sequence of one of the pre-settlement indigenous groups. The text gives the name as the Moonleaf Tribe.

The silence that followed was different from the previous silences.

She was still looking at him. Her expression had not changed in the ways it usually changed when she was managing information — no visible calculation, no social adjustment, no reaching for the smooth answer. She was simply looking at him, and he could not read what was in the look, which was unusual. He had gotten better, over the past weeks, at reading her.

He waited.

I know the term, she said finally. From the same archives, presumably.

The text in the archives has been partially redacted, he said. The date of the tribe's dissolution is missing. The cause is missing. The names of the individuals involved in whatever ended them are missing. He paused. I asked Caelum about it.

A fractional stillness. What did he say?

He asked me where I had heard the name. He was too careful about it for a casual question.

She lowered her eyes briefly — to the floor, to the root system of the central cherry tree — and then raised them again. You are asking the wrong questions, she said.

Which questions should I be asking?

The ones about the music, she said. The arrangement is ready. We have the competition in three days. That is what we should be thinking about.

Those things are not mutually exclusive.

They are today, she said, and there was something in her voice that was not the usual performance — something with an edge to it, something that was asking him, clearly and directly, to let this particular thread go. Not permanently. Just today.

He looked at her for a moment longer. Then he opened the violin case.

From the beginning, he said.

Thank you, she said, quietly, and moved to her opening position.

He raised Aetheris and played.

But he kept the questions, all of them, in the part of his mind that did not let go of things, and at the end of the session when he was walking home through the morning streets of Oakhaven he stopped at the entrance to the lower quarter's archive office and stood there for a moment looking at the door.

Then he went in.

The archivist was a small precise woman who had been managing the lower district's historical records for longer than Valerius had been alive, and she found what he asked for without comment — the original, unredacted census records of the indigenous groups that had inhabited the Oakhaven valley before the city's establishment, the documents from which the Academy's copies had been made, and from which certain things had been removed before copying.

He sat at the reading table and opened the file.

The Moonleaf Tribe. Weave-Dancing practitioners. Last recorded population: forty-three individuals. Status as of the twenty-third year of the current Royal Charter: dissolved by order of the Royal Council, grounds listed as public safety and Resonance contamination risk, specific incident redacted at the request of the Council.

He read this twice.

Dissolved by order of the Royal Council.

He sat for a long time in the archive with the document open in front of him and the morning light coming through the small high window above the reading table, and he thought about a woman in orange who had come to a ruined cathedral that had once been a site sacred to the people she had come from, and who knew where the light fell at every hour of the day because she had been here before, and whose skin was the color of something being slowly replaced by something else.

He thought about the Glass-Heart Curse, which he had read about in the medical texts at the Academy, which was listed there as a Resonance-based curse of unknown origin, specific to practitioners of ambient Cadence techniques, with no known cure.

He had not, until this moment, connected those two pieces of information.

He sat in the archive for a very long time.
