Morty knows he shouldn't be screwing around with multidimensional shit. It's dangerous, it's impractical, it's blah blah blah. But it's a potential key to unlimited energy, how does nobody see that? He's built a dimensional siphon (it kind of looks like a cardboard box with a funnel and a TI-84 taped to it, but it damn well works), keyed in the dimensional coordinates to a random plane, and by God he's going to use it.
He flips the switch and waits for the energy bar to fill up.
It does! It fills up very rapidly. Then it explodes, along with the box. There's rather more smoke than there should be, and once the smoke clears someone is standing there.
"Whoops?" Morty says faintly.
Bella does not get up before sunrise; she gets up a couple hours later, figures out a shower herself, puts on some of her new clothes, and heads to breakfast to be nourished for her powers testing appointment.
Breakfast is available, including Kharoline frybread, which is presumably called something different here but is not labeled.
Nobody she knows seems to be breaking their fast at the moment, though a blonde girl floating several inches off the floor is peering at her thoughtfully.
"...hello," says Bella, loading up her plate with Kharoline frybread.
"Oh! Hi. I was just noting that I haven't seen you around, which is weird because I've seen everybody around and I remember them all perfectly, which would imply that you're new, which is interesting. Sorry for staring. I'm Ariel. Stormhammer."
"Bella Swan. Yes, I'm new. Morty had an interplanar accident."
"Really well! I like it here and I'm gonna stay, my plane sucks."
"Ooh, that's way better than the alternative! Not better than your plane being cool, I mean, that part sucks, but it makes us kidnapping you a lot less problematic. Wanna sit at my table?"
Ariel, carrying her own tray of frybread and various syruped meats, leads Isabella over to a table containing a handful of other people: a dark-skinned girl covered with swirling purple tattoos, a couple of skinny white boys, and a living marble statue with feathered wings sitting next to a boy wearing a techy-looking visor thing. "Hey guys! This is Bella, she's new and from another universe."
Most of the table nods to her. Visor boy looks up sharply. "Interesting. I do hope you realize the fact you're recognizably human flies in the face of the laws of evolution."
He frowns. "Even worse. Though I suppose an intelligent designer could have been working from an existing template."
"If you don't have evolution, can you still breed horses and dogs and all that?" one of the white boys asks. "-Xan, by the way, is my name, I'm Xan. The sciency one is Hakim, the statue's Sky, my boyfriend is Leo, the girl with tattoos is Sally."
"It's nice to meet you all. I believe people do breed dogs and horses, yes."
Hakim nods. "You've got evolution, then, wherever your humans came from. Though I suppose you could have inheritance without that implying evolution per se... hmm. -I'm an engineer, why am I going on about biology."
"Because you're a nerd," Sky says fondly. "Nice to meet you, Bella. What kind of powers do you have?"
"I'm what's called a subtle artist, which means telepathy-type powers and also a little weak teekay. Some subtle artists are pyrokinetic but I'm not. I also know barely more than high school level arcana from my world's magic system."
"Oh, interesting - kind of a Martian Manhunter situation, powers unexceptional for the home world but incredible anywhere else," Sky says thoughtfully.
"And you call me a nerd," Hakim scoffs. "Did I hear that right - you learn magic in high school?"
"We're learning magic in high school," Xan points out.
"Public high school, then," Hakim says impatiently.
"Not everybody took the class but yes, I was in honors arcana in public high school."
"Some people just weren't interested but there was actually also a test you had to pass to get into even the non-honors level, and almost half the people who took it failed."
"Oh," Hakim says, mollified. "That makes sense, then. Aptitudes vary."
"What's your world's magic like?" Leo asks. "I want to know if I should be jealous that I wasn't a messiah of Bella-world magic instead of ours."
"I don't think arcane magic has messiahs, and I know way less about divine magic. I could show you a spell but there are a lot of different ones, I'm not sure what you want to know."
"Ooh, if you can show us a spell that'd be cool. Mostly I just meant like, what's the natural aptitude they're testing when they test whether or not you're good enough to take the class? Like, for us that'd be your willpower and ability to control your own mind. And how flexible is it, but I guess you're saying it's very flexible."
"It was more of an intelligence test, but it was architected specifically to check if you'd be able to do all the steps of learning to read scroll notation. I know almost twenty spells, they're not all suitable for a cafeteria demo but I don't want to list them all, should I just pick something or is there anything in particular you wanna see?"
Bella rummages in her belt pouch and comes up with a dead firefly and says a magic word to make her ponytail holder glow.
