"—so Serahila should have magic too, that's how it's supposed to work, but nobody knows what it is. And she doesn't like to talk, which is why I'm saying all this for her. My magic's with ink and paper, which is all one magic even though it sounds like two different things, and Mercy does thread and cooking, which is exactly the number of different things it sounds like. People don't usually have two different kinds, but Niva got hers because she was struck by lightning, which she doesn't like talking about, probably because it was painful and scary. And Rook is a plant mage and Sedge is a stone mage, and that's everyone at Discipline."
