It is open hours, technically, but one has come in for the better part of an hour, and the shop has taken on a particular hush. Callum has spent the morning copying, as he spends most mornings copying.
Today's book is one he has never seen. It exists nowhere he can put his hands on. He has been told it lives somewhere behind a locked door in the Dominion, and he has decided to see if the sight can reach through a locked door.
The shallow copper basin is set at the center of the small side table. Beside it, in the order his second mentor taught him: yarrow to the left, salt to the right, a stub of beeswax candle in front, lit. The grimoire beside the basin is a blank one, waiting. Callum’s pen is inked and he has been holding this working for the better part of an hour.
The Sight is turned - not forward, not backwards, but through. Callum is looking at a page he has never seen, in a room he has never entered, in a house he has never walked past, and he is copying what he sees onto the blank page under his hand. Character by character. He does not stop to consider what he is reading. He will read it later, when the working is closed and he is permitted to be a mind again instead of a hand.
But the cost of his magic has begun to mount the way it always mounts. Behind his eyes, a hot small pressure. At the edges of his vision, the shop has begun to soften into gray. His breath is slower than he would like; his pulse is a distant polite thing checking in from another room. Callum knows, to the minute, how long he can sustain it before the cost comes due all at once like a thunderclap. He’s ignoring all of it, insistently.
The edge of a page turns beneath his hand - not the blank one, but the reference grimoire beneath it, the one he copied himself over three winters when he could not sleep - and it catches the pad of his index finger, opens it in a single fine line.
It’s a papercut. Absurdly, catastrophically ill-timed.
A single drop of blood falls, without asking, into the basin and the working shatters immediately. "Fuck," Callum says, low and heartfelt. He drops his pen. Fine - this is fine. That is the entire hour, but it is fine.
Only then does he notice the person standing in front of him. Callum lifts his eyes. The shopkeeper’s preamble slides into place by reflex. “Can I help you find anything?”
Then, because he cannot help himself, he gestures toward the basin as though it is the result of an ill-prepared recipe rather than an hour of ruined divination. “Here. Have at it if you want. If you add a drop of your blood, it’ll show you what our futures hold.”
