Corren cleared a space on the worktable and set the raw ore fragment down in the center of it, angling the lantern so the light fell more directly across its surface.
“Trace inclusions are common enough in raw ore,” he said, without any real preamble.
“Gold especially.
It doesn’t form its own deposits the way iron or copper does, not usually — it rides along inside other ores instead, in amounts too small to matter for most purposes.
A few flecks, buried deep, easy to miss entirely unless you’re specifically looking.” He tapped the fragment once.
“That’s what your third structure is.
Gold.
A very small amount of it.”
Wren stared at the fragment, faintly deflated.
“That’s it?
Just gold?”
“Just gold,” Corren agreed.
“Nothing sinister about it.
Half the raw ore pulled out of this region probably has a few flecks buried somewhere inside it, same as this one does.” He set the fragment back down.
“What’s actually worth paying attention to isn’t what you found.
It’s that you found it at all.”
“I don’t follow.”
“A trace inclusion that small doesn’t show up on a basic identification circle.
Not reliably.
Most trained mages need a specialized reading — finer runework, more mana behind it, purpose-built for exactly this kind of detection — before something that minuscule resolves into anything more than noise.” Corren’s eyes flicked toward Wren’s notes again, the rough half-formed sketch still sitting there on the page.
“You got a shape out of it.
An actual shape, not just a suspicious blur, using a first week spell you’d drawn from a diagram that same evening.”
“I didn’t even finish resolving it.”
“You got further than you had any right to, with the tools you were using.” Corren said it plainly, without any particular warmth, the way he seemed to deliver every observation regardless of how remarkable it actually was.
Not the gold.
Your precision.”
Corren moved to his own desk, pulled out a scrap of paper, and began writing without asking whether Wren was ready for it.
“If you’re going to work under me properly, you’ll need a foundation better than whatever’s in that servant’s guidebook you’ve been relying on.” He didn’t look up while he wrote.
“The tower library’s on the second basement floor, past the practice rooms.
Ask the archivist for these by title — she won’t hand them over without one.”
He finished the list and handed it across.
“Grains and Veins: A Taxonomy of Common Ore.
Start there.
It’ll teach you to recognize the ordinary before you go chasing the extraordinary in every sample you touch.” He tapped the next line down.
“On the Composition of the Cast: Vessel, Rune, and Redirection.
Denser reading, but you’ll need it if you’re going to keep pushing spells past where a first-year apprentice has any business going.
Understanding why a circle costs what it costs will do more for you than brute-forcing your way through another two-hour session.”
“And the last one?”
“Baseline Properties of Worked and Unworked Metal, current edition.
Consider it a reference more than a read — you won’t need all of it at once, but you’ll need pieces of it constantly, and I’d rather you know where to look than come ask me every time you hit something you could have found yourself.” Corren set the pen down.
“Read what you can before our next session.
I don’t expect you to finish all three.
I expect you to have started.”
Wren folded the list carefully and tucked it into his notebook, alongside everything else that had accumulated there over the past few days.
“Yes, sir,” he said.
“One more thing.” Corren’s eyes flicked toward him, briefly sharper than the rest of the conversation had been.
“Whatever you find in that library, whatever you learn — bring it here before you decide to test any of it on your own.
I’d rather waste an afternoon hearing an idea I already know won’t work than waste a week finding you passed out over your own desk again.”
The stairwell down to the second basement floor still felt unfamiliar in a way most of the tower no longer did — Wren had walked these steps exactly twice now, both times with somewhere darker on his mind than a library.
The practice rooms looked the same as they always did on his way past: heavy doors, brass plaques, the same faint scorched smell drifting out from underneath a few of them.
He kept his eyes forward and didn’t slow down near 4B.
The library sat at the far end of the hall, past the last of the practice rooms, marked by a door taller and heavier than any of the others — dark wood, no gold or iron worked into it, just deep, careful carvings of shelves and open books running the length of the frame.
Wren pushed it open, and the smell hit him before anything else did — old paper, dust, and something faintly metallic underneath it all, like even the books down here hadn’t quite escaped the tower’s general character.
Shelves rose higher than he expected, disappearing up into shadow well past where any lantern light reached.
A woman sat behind a desk near the entrance, elderly, sharp-eyed, a pair of spectacles perched low enough on her nose that she seemed to be looking over them rather than through them.
“New face,” she said, before Wren had gotten more than three steps inside.
“Apprentice, or lost?”
“Apprentice.
Mage Corren sent me.” Wren held out the folded list.
“Said you wouldn’t hand these over without a note.”
She took it without standing, unfolded it, and read it over with the particular slowness of someone who’d learned not to trust anyone’s handwriting at first glance — least of all Corren’s, apparently, given the small, dry sound she made somewhere in her throat.
“Grains and Veins, On the Composition of the Cast, and the current Baseline Properties edition.” She looked up at him, something faintly assessing in the look, not unlike the one Adeleine sometimes gave him.
“Corren doesn’t send first-years down here.
Not usually.
Not this early.”
Wren didn’t have a good answer for that, so he didn’t try to give one.
She studied him a moment longer, then folded the list back up and set it aside, apparently satisfied with whatever she’d been checking for.
“Follow me,” she said, standing at last, already turning toward the shelves.
“And mind the third row.
Floor dips there, and I’m not carrying you back up nine flights if you crack your skull open.”
