Bella cackles. I'm not adopting everything in sight! Just the very small number of therapy patients on hand, and reinventing wizardry, and dispensing useful nonhorrible ideas from my plane, and trying to socialize the adorable self-insert-fanfiction-writing child!
It's not specific to toddlers. Or other worlds, exactly. You can write self-insert fanfiction if you're anybody - particularly if you are a teenage girl - and about anything, including perfectly dull stories about an ensemble cast who work at a café or something. It is stereotypically really badly written and put up for free on the ethernet instead of published in book form.
He wiggled his left leg. He wiggled his right leg. The ceiling felt like it was pressing down on the back of his neck and the floor felt like it was buzzing under his feet and his father was going to be so disappointed and Fëanáro ran away.
He ran left, left, right, left, through the corridors where he'd hidden last time this happened because if he went there they'd know to look for him. He ran right, left, left, straight, second left through the wing of the palace that was for the future when the King had many children and many grandchildren except that was never going to happen and it was Fëanáro's fault.
And then he turned a corner and noticed that he was not in the palace after all.
"Where are you going to land?" she murmurs. This is not teenage girl on the ethernet. It's not something she'd expect to see in a bookstore, either, but not because it's not good, it's just not - bookstore-y.
"Uh, I wasn't there. I've never been in or even very near a war and I haven't read that history book yet. Maybe you should just pop out in Emily, that seems more like the sort of thing that might happen and I can tell you all about Emily."
"Emily's a building! She woke up one day, I don't know how, it's not very common, and now she's an alive building with a mind and everything; she's very friendly and she can move bits of her architecture around and helps people find their classes and not have to wait in line for the bathroom and stuff. I like her a lot. Anyway, she rearranges a lot and can have as many doors as she likes, and while I wouldn't expect lost Eldar to come wandering out of her every week she's definitely one of the likelier places if you're going to do it at all. I'd just - I'd just gone left past her when I went into the building where I had my accident."
...Maybe.
"Uh, that book isn't actually handwritten. Handwriting isn't hardly ever that neat. It's scribed off with magic."
"...It would, probably, actually be faster to take you up through the just-past-high-school wizardry I've got and have a second brain on the problem than to try to do it myself," she acknowledges. "But you have to be really careful. A lot of spells are dangerous and since I can't go get them out of books they might be dangerous even if they're not supposed to be."
