Good enough.

Then: magic time. How much does she know already?

...Not much, especially not that she'll volunteer. 

(She knows more about wards and the like, the kind of complicated working that underlaid her castle, though she has a frustratingly (to her) vague understanding of it. She's clearly curious, but no one in her immediate, living family used magic. They had no books they considered appropriate for her on it, and the books she stole weren't very helpful, many written in an archaic language she'd been struggling to understand in stolen moments of the night - which means that what arcane knowledge she does have is in that same ancient tongue.)

(This is present in the absences of what she says, mostly, revealed in the questions she asks and the questions she avoids. She's not willing to explain herself, her life, or her knowledge yet.)

She does recognize the language and several of the metaphors that reveal themselves in Lily's speech.

"I hadn't though there were that many copies of those books still extant. They were being burned, last I knew. Though I suppose that was farther north... Regardless. You could have worse foundations, and with this at least I remember what I was thinking well enough to bring you up to the modern interpretation."

" - Did you write them?"

"Long ago, yes."

Very conflicted noise. Then, hesitantly: "It'd have been bad if they all burned." 

"Some people are of the view that the source of knowledge taints the knowing."

"That's dumb," she says, before she can censor herself. 

"It's good you agree. That will make this easier."

She hesitates again, but... "They're good books," she says, quietly. "You know a lot about magic."

"It is a passion of mine. And I am in a somewhat unique position."

"As the Demon Queen?"

"Indeed. I have delved further and deeper than others."

"You'll teach me all of it?"

"As much as you can handle."

"So, all of it."

"If you live that long."

"I'm not going to be dumb."

"I do hope not."

"It'd be a waste of your investment?" she asks, sounding sarcastic. 

"Yes. I value my time, and would not see it wasted."

Scornful noise. 

"Have you forgotten to what purpose I brought you here?"

"So I can grow strong enough to be worth murdering."

"I'm not doing this for my health, you know."
