Nod.

And he's done eating.

"Anyway, I'm gonna go figure this spell out and do some more research, tell you about it later—by the way did you see the crystal I left at your room?"

"Yeah?"

"Okay so I'll call you there once I have this figured out."

"I don't have my crystals with me all the time, if I don't answer wait an angle and try again."

"Alright."

And soon he's done eating, so he says goodbye to Kaylo and returns to the library.

The library is still there and still has books.

Good! How about books on witchcraft?

There are some! Nothing instructional though.

Hmm, what are they about if not instructions? Is there anything on the theory? Anyone have a clue where the magic feeding the potions comes from?

Some speculation, some history, some studies on potion effects. Nothing definite or even very solid on his question.

Shame. Does the librarian know where he might get witchcraft instruction, and how much it might cost? And for that matter do they know where he might announce he has unique otherworldly magical doodads to sell?

From a witch. A lot of the shops have apprentices, though probably mostly younger than him. They exchange labor for tutoring; money doesn't typically change hands. He could take out an ad in the paper.

Oooh okay good to know. How does he do the ad thing?

He sends a letter to the paper marked attn: advertisements.

Alright cool. Are witch shops open at the moment? If so, he'll want to go visit that one he bought potions from.

It's open!

So there he goes!

"Hey, can I help you find anything?" says the elf girl at the counter.

"Not exactly—I'd like to apprentice, actually."

"Oh, I see. Do you have previous witchcraft education at all?"

"Nope, I'm actually not from this world, got accidentally stranded here."

"Huh. Uh, okay. So why do you want to be a witch?"

"It's apparently this world's only form of magic I can use and I am very much a magic nerd. Plus I can convert it into my world's magic."

"What are the limits on your schedule?"
