"How did these items get made if there's no way to learn magic? Are the magicians homeschooling their children and not writing any books? How did you learn?"
"Half this stuff is antiques," says the shopkeep. "Look, asking me a dozen times isn't gonna make the answer more to your liking. I don't have Hogwarts in the basement, deal with it."
"But where do you get the stuff that isn't antique - who made the Avalon itself? - isn't anybody panicking about the medallion supply? -"
"Kid, nobody knows how to make medallions."
"But some people apparently know how to make luck charms and protection amulets!"
"I'm not going to give out my suppliers' personal information. I wouldn't do it even if you weren't annoying."
"There have to be books -"
"Does this look like a library to you?"
"It looks like so much tedium to me," confesses Ren. "I know magic is exciting and the results are exciting, but all that math and looking things up!"
"It is sort of like Sudoku, isn't it? The comparison hadn't occurred to me," says May.
"It's fun in the same way that Sudoku is fun. You figure out what to put where by comparing numerical values."
"Well, I do actually like Sudoku, so I don't really have any non-obvious explanations."
"I only sort of get the appeal of puzzles. Like, the process seems among the pleasanter processes you could go through to get things, but the thing isn't worth having."
"In my case, it's similar to running laps. You don't do it because you want to get to the other end of the track and back, you do it because you want to be better at running when it's important."
"I suspect so. I've never spent enough time not doing any kind of puzzle to have trackable differences in improvement, but I do know that puzzles-in-general have gotten easier over time, not just ones I already have experience with."
"Also, I'd go insane if I didn't give my brain something challenging to do, and there's only so much schoolwork I can do."
"And schoolwork isn't usually challenging in a satisfying way. Standard 'enrichment' is just 'more of it'."
"I wouldn't dislike it on the level of performing the action, but I suspect I would be somewhat dismayed by how much longer it would take to complete a spell."
"It would be pretty hard for me to want fancy dragon powers more than I already do but I would find a way to manage if they let me skip calc."
"On a practical if not necessarily academic level...what ought we to do once we graduate high school, come to think of it? It's not like you can study thaumatology in college. If we were more certain there were no extant magic schools it would have to be education, wouldn't it..."
"I enjoyed college but I'm not sure either of you would get along particularly well with education majors or the instructors," Ren mentions.
"And we were thinking we'd teach adults anyway, right? You need less formal training for that than for wrangling a classroomful of kids."
