"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?"
"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."
