Corren didn’t look up when Wren came in, which was ordinary enough that Wren had stopped noticing it somewhere in the second week — the man’s attention arrived on its own schedule and resented being summoned early — so he set his notebook on the worktable, pulled the sample case toward him, and started laying out the morning’s set in the order he’d been taught to lay it out.
He got four fragments down before he made himself say it.
“Mage Thale’s going to put a redirection modification in me.” Wren kept his eyes on the samples.
“Upper back or chest.
She hasn’t decided which yet.”
The pen kept moving.
“She set conditions first.
Six weeks of careful casting, a crystal in the circle every time, no exceptions, and she wants it done under your eye.” He set the fifth fragment down and squared it against the others out of a nervousness he didn’t particularly want to look at.
“If I overcast inside that window, the six weeks start over.”
The pen stopped.
“Sit down.”
Wren sat.
Corren finished whatever line he’d been in the middle of, capped the pen, and turned in his chair with the unhurried thoroughness of a man who intended either to look at something properly or not at all.
“I told Vaelen about your chest,” he said.
“In case you were wondering how it reached his desk.”
Wren hadn’t been.
He was now.
“You’d been holding your breath at the top of the stairs for three weeks and correcting your own posture whenever you noticed me watching, which is worse than a limp, because a limp is honest.” Corren said it the same flat way he said everything, without any suggestion that Wren was owed either an apology or a defense.
“I don’t manage people.
I do report equipment failures.”
“Is that what I am?”
“You’re an apprentice with an organ he’s already spent six years of, and I’d rather have you for forty of them than four.” Corren pulled a drawer open, took out a small case Wren hadn’t seen before, and set it on the table between them.
“The conditions are acceptable.
I’d have imposed most of them myself if Thale hadn’t gotten there first, and I want to be clear that I’m agreeing to them as your instructor rather than as a favor to you, because you’re going to want to negotiate with me somewhere around week three and it will save us both an afternoon if you understand now that there’s nothing here to negotiate with.”
“Yes, sir.”
“Good.” He opened the case.
Inside, seated in cut felt, sat a row of gathering crystals — clear, faintly clouded at the cores, each about the size of a thumb joint.
“Take one.
You’ll be using them until Thale tells me otherwise, and you’ll find the experience less pleasant than you’re expecting.”
Wren looked up at that.
“Less pleasant.”
“You’ve been reading metal through your own ribs for six weeks.” Corren shut the case.
“Take the pain out of the circle and you’ll discover how much of your technique was ever technique, and how much of it was just flinching in the right direction.”
The first cast went perfectly, and Wren hated it.
He drew the identification circle the way he’d drawn it a hundred times now, dense cluster at the center, outer ring closed last, and seated the crystal in the small notch at the circle’s edge the way Ellowen had shown the whole class on their second day, back when a gathering crystal had been a thing that happened in a lecture rather than a thing that happened to him.
The final line closed.
Gold light rose off the page in thin layered sheets, hung above the fragment, and began tracing outward in the familiar slow bloom of veins and grain.
Nothing happened in his chest at all.
Wren sat with that for a moment, waiting for the ache to arrive the way it always arrived, patient and low and about a half-second behind the light — and it didn’t come, and the absence of it was so total that he found himself pressing a hand flat to his sternum to check, which was a stupid thing to do and he did it anyway.

The projection held.
He read it.
Iron, copper threading, the whole ordinary architecture of a sample he’d catalogued twice already.
He held the circle open past the point where he’d normally have let it die and felt only the slight cooling of the crystal under his fingers, its clouded core going a shade thicker as it took what he would otherwise have been paying.
Forty minutes.
He stopped because Corren told him to, and not for any other reason, and Wren wrote that number down and looked at it for longer than the number deserved.
Forty.
It should have felt like something.
The trouble surfaced on the fourth read of the afternoon.
Corren had set him a fatigue series without calling it that — the same fragment, the same circle, the same question asked eight times in sequence, log every result, note every discrepancy.
Tedious work, and Wren had assumed the point of it was the tedium, some standard exercise in consistency handed to every apprentice who’d started getting pleased with himself.
The first three reads matched.
The fourth came back muddier.
He assumed he’d made an error, which was reasonable, so he redrew the circle from scratch on a fresh sheet, checked every line twice against the diagram, seated a new crystal, and ran it again.
Muddier still.
The copper threading, which had resolved on the first pass into clean bright veins running alongside the iron, now came up soft at the edges, the boundaries between the two metals going vague in a way that had nothing to do with his runework at all.
Wren checked his hands.
Steady.
He checked the diagram.
Clean.
He checked the crystal, which was fine, and the paper, which was fine, and then he sat back and looked at the fragment itself, sitting there in the middle of a perfectly good circle, giving him a worse answer than it had given him an hour ago.
It’s not the spell.
He picked the fragment up and turned it over.
It looked the same.
It weighed the same.
He set it down, took a fresh fragment from the same case — same region, same grade, catalogued a week apart — and ran the identical circle on that instead.
The read came back clean.
Sharp veins, hard boundaries, the whole structure sitting there obvious and legible as a diagram in a book.
Wren looked at the two fragments side by side for a long moment, and then he went and stood at Corren’s desk without entirely deciding to.
“The sample’s changing,” he said.
“Not the circle.
I’ve run eight reads on the first fragment today and the last four came back progressively worse, and a fresh one from the same case reads clean on the first attempt.
The metal’s holding the rune worse than it did this morning.”
Corren didn’t look up.
“Yes.”
“You knew.”
“Everyone knows.
It’s called fatigue, it’s been documented for two hundred years, and it’s in the front matter of Baseline Properties about nine pages before the section you actually read.” He turned a page.
“Cast on a metal often enough and it stops cooperating.
The structure that made it worth reading gets a little less definite every time you ask it a question, until eventually you’re interrogating a rock that has nothing left to say.”
“How much of it comes back?”
“None of it.”
Wren stood there.
“There’s no rest interval,” Corren went on, still reading.
“No recovery curve.
People have looked; there are three separate monographs on the subject and they all conclude the same thing in different numbers of pages.
A fragment that’s been worked has been worked.
You can anneal it, reforge it, dissolve it and pull it back out of solution, and what you get at the end is a different piece of metal that happens to contain the same atoms.” He made a small note in the margin.
“It’s why my sample budget is what it is, and why you’ll be logging every cast you make on every fragment from here forward, since you’ve now personally verified the reason for a rule you’d have found tedious if I’d simply given it to you.”
The organ does not reset.
Wren didn’t say it out loud.
He stood at the edge of Corren’s desk with his notes in his hand and the sentence arrived anyway, fully formed, in Vaelen’s voice and Thale’s both — every overcast leaves a little less capacity than you started with, that portion is done, it won’t come back — and it occurred to him, with a clarity that felt almost pleasant, that he had spent a month and a half believing this was a fact about lungs.
He laughed.
It came out short and wrong and entirely without his permission, one flat syllable in a quiet workshop, and Corren’s pen stopped.
“Something’s funny.”
“No, sir.” Wren heard how steady his own voice was and found that interesting too, in the same distant way.
“Nothing’s funny.
I’m sorry.”
Corren looked at him for a moment longer than the exchange warranted — the same measuring look he gave a sample that had come back off-spec — and then went back to his page.
“Log the series,” he said.
“All eight, including the four you thought were errors.
Especially those.”
Wren skipped dinner again.
He told himself it was the logging, and the logging was real enough — eight reads, transcribed properly, with the drift marked at each interval and a note about the control fragment underneath — but he finished that by the second hour and stayed at his desk anyway, and by the third he’d stopped pretending the notebook in front of him had anything to do with Corren’s assignment.
The back pages were where he’d left them.
Shapes in the margins that weren’t copied out of anything, a rune with one line too many that he still didn’t understand well enough to explain, and beneath it a quarter-page of empty paper he’d been circling for three weeks the way you circle a room you’ve been told not to go into.
Six days until Thale wanted to see his diagrams.
Wren turned to a clean page instead, near the middle, where the notes were still respectable, and wrote out the thing he’d been carrying up nine flights of stairs since the afternoon: that every table in Baseline Properties measured a metal by what it was, and the retention column measured what it would agree to do, and neither of them measured the thing he’d actually watched happen today, which was a fragment agreeing a little less each time until it stopped agreeing at all.
Nothing in the book had a word for that.
He checked.
He went back through Grains and Veins and the front matter he’d skipped and forty pages of Composition of the Cast, and found fatigue described eight separate times as a limitation — a nuisance to be budgeted around, a reason to order more samples — and not once as a property.
Nobody had thought to ask what a metal was doing while it fatigued.
They’d only ever asked how much longer it would last.
Wren sat back and looked at what he’d written, and the ache in his chest picked exactly then to remind him it was still there, low and familiar and no worse than usual, a quiet standing account he’d stopped noticing the way you stop noticing the weight of your own boots.
He turned to the back pages.
He added a line to the shape that already had one too many, and this time he left it on, and he went to bed with the lantern still burning because blowing it out would have meant looking at the page one more time on his way past.
