Of magic? But you didn't wind up a witch. That's... hm. I guess it doesn't make much sense how the world decides who's going to be what, here. [He's wondered about that. Why he has magic, why he isn't growing scales and talons instead.] I was normal before here. We don't, uh, we don't have magic at all back home. We have a lot of dragons, though, so I've wondered, you know, why I'm a witch instead of a- a dragon or something.

[A quick shake of his head, and he hastily jots down a few more notes in the margins of the page he's working on.] Oh, no, it's from home. When you feed a gronckle - that's a type of dragon - a certain blend of minerals and stone, they spew out molten metal, gronckle iron. When you work it, it's strong but it's really light.
