The record was not in the eastern wing. It was in Casvar's own rooms — a level of the citadel Kael had not been in before, which told him something about how long Casvar had been holding it as private rather than institutional knowledge.
The rooms were spare in the way of someone who had been somewhere for a very long time and had slowly removed everything that wasn't necessary. A few cloth strips, older than Seren's but in the same vein. The wooden case on a shelf. And, in a cabinet that Casvar opened with the deliberateness of someone who has not opened it recently, a document.
Not cloth. Stone — a thin slab of dark stone with writing pressed into it rather than carved, as if by sustained heat rather than a tool.
Casvar set it on the table between them.
He said: "I can read it to you. Your vocabulary—"
Kael said: "Read it. I'll ask when I don't know a word."
Casvar read.
It took a long time and Kael asked a great many questions and by the end he had one hundred and ninety-four words and an understanding that required him to sit with it for longer than the reading took.
The circle in the eastern wing was not a weapon platform. It had not been built for directed release. It had been built as a receiving structure — a place where accumulated Resonance could be formally redistributed rather than released destructively. A mechanism for what the stone record called the return: the orderly transmission of soul energy from an accumulation point back into the world, not as a weapon but as — nourishment was the closest word Kael could arrive at. The energy the dead had shed, held and accumulated and then returned deliberately to the places it had come from. The living world's borderlands. The fields and cities and ordinary places where the living lived.
The Kaer four hundred years ago had not understood this. Or had understood it partially and used the circle for the only purpose he could imagine for a structure that concentrated energy: as a weapon. And it had killed him and three hundred others and burned the eastern wing.
The circle had then been restored — Kael understood now, reading between Casvar's careful accounting, that Casvar himself had restored it, shortly after taking his position as Valdrek's primary Soul-Lord — and had been left available for a Kaer who would eventually arrive and do what the previous one had not.
He said: "You always intended the return."
Casvar said: "Yes."
He said: "Not a weapon. A redistribution."
Casvar said: "The release was a weapon because the situation required it. The circle was built for something else. I hoped a Kaer who had been taught carefully enough would understand both uses and be able to choose between them."
He said: "You could have told me."
Casvar said: "A man who knows about the return will use the release only as a last resort. Which is correct. But the last resort arrived before I had time to teach the rest."
Kael sat with that. He turned it over with the precision he applied to everything. He found that it held. He found also that it held two things simultaneously that were not contradictory: that Casvar had managed him carefully and instrumentally, and that Casvar had been building toward something more than the weapon since before Kael arrived.
He said: "How much accumulation does the return require."
Casvar said: "More than you currently have."
He said: "How much more."
Casvar said: "I don't know exactly. The stone record was written before the Resonance framework was established. The units of measurement don't correspond cleanly. But—" He looked at the teal instrument in the wooden case. "When the thread begins oscillating rather than only tracing, I believe we will be close."
Kael said: "How long."
Casvar said: "At your current accumulation rate, with the souls continuing to arrive from the border populations — months. Perhaps half a year."
Kael said: "Then we have time to do it correctly."
Casvar said: "Yes."
He said: "And the circle needs to be modified. The current configuration is for the release — the outward directed discharge. The return requires a different orientation."
Casvar said: "Yes. I know what it requires. I have known for four hundred years."
Kael looked at him.
He said: "You've been waiting a long time."
Casvar said: "Everything in Valdrek takes a long time. That is the nature of a world without a sun."
He said it without inflection. Assessment, as always.
But Kael had one hundred and ninety-four words now, and he understood the language well enough to hear what was underneath the assessment. Not patience. Something older and quieter. The specific condition of a person who has been working toward something for so long that the working has become the relationship they have with time, and the arrival of a moment where the working might end is not purely relief.
He thought: I have been in Valdrek for forty-seven days after the release. I have been here for approximately ninety days total. And I can hear that.
He thought: that is either impressive progress or a sign that the thing I am learning to hear has been trying to be heard for a very long time.
He thought: probably both.
