"Well, how were the other two kinds of magic created? No, wrong question, artifact creation would be a large number of interrelated things, possibly its own field of study, not a monolithic event. What can you tell me about how magical girls came to be?"
"Dang. Can you at least tell me who it was classified by?"
"Oh, well. Can I get some...textbooks, or something, on artifact creation?"
"It varies. For me, it lasted hours. One of the other children my teacher kidnapped only spent a few minutes at it."
Charlotte, who has started skimming the textbooks just fast enough to transcribe them into the tablet, winces slightly.
A moment after that, her magical girl magic presents her with a new spell.
"Ooh, new magical girl spell." Pause. "Annnnd I'm not sure I should cast it while in Milliways because this place has its own time-screwing-around-ness but the incantation is 'Possibility Vision'."
"Hey, Bar, do you know if your time-weirding would actually interfere with Bella's spell?"
"Shoulda been more specific, I meant Milliways time-weirding. Does it apply to the whole place including backyard and upstairs, as far as you know?"
"I kind of wanted to see, but oh well; the important part is that you can use it to seriously mess up some evil fluff."
