He explains!!!

She has notes on that too.

"Have you developed spells for teleporting between planets in the same universe?"

"No, it hasn't come up before, but it should be doable."

He shakes his head and laughs.

"What?"

"I've spent the last twenty years figuring out how to do it without magic."

"...oh."

"Anyone can learn the magic?"

"Yeah. Well, some people don't get anywhere but that seems to be a general intelligence thing."

"How do you learn it?"

"Somebody walks you through scrolls for the easiest kind of spell and you go from there."

"Excellent, let's go."

"...I'll have to find one, hang on -"

She rummages around in the boxes. Telekinesis is involved.

He waits something resembling patiently.

She turns up a scroll for Prestidigitation and starts explaining it.

Then he will learn magic! And be very pleased about it! "You should put this online, with a video tutorial if needed -"

"Can't, the Valar might be stupid."

"- why, does it do something really dangerous?"

"This one doesn't. Some of them can. I haven't invented any combat spells but they're a big thing in Materia. Anyway, they might do something stupid even if there weren't any actually dangerous magic in circulation."

"I don't really think so. They don't interfere with our internal affairs."

"They broke a bunch of stuff in the flat Arda."

"Why?"

"It was going too fast for them and they didn't think people should get to opt out of the time slide en masse."

"...that's bizarre. Whyever not?"
