Morty wasn't even trying to do anything this time. He was just fucking around with some cardboard, and okay, maybe it turned into an eldritch sigil of some kind, and then it blew up in his face, and now there's people in his room.
"Huh. Well, mysterious nudes, my name is Ariel. I've been sent to provide you with clothing-" she takes two large, somewhat formless bathrobes from her backpack and tosses them to Gavriel and Herod- "and escort you to visit Louis for a threat assessment. If you do not wish to cooperate, I will pick you up one over each shoulder and take you there anyway. Questions? Comments? Concerns?"
The two will put the bathrobes on to the best of their ability given their extra limbs.
"We will go willingly. No need to take us by force."
"My only comment that if you were a boy I might have preferred to be taken by force, maybe next time we crash somewhere."
"Excellent! That makes it much easier. And my apologies for having tits, Gavriel."
She leads them out the door. There are some students leaning out their own doors to stare, but Ariel glares them back into their rooms. "Don't mind the peeping Toms, they're just wondering why I got called in."
Gavriel strust proudly down the hallway winking at the cute guys.
Herod feels sufficiently covered to just ignore the looks. "Is that a common thing? Needing to cart out people for threat assessment, that is."
"Not really, but when two possible demons abruptly pop into existence in the boys' dorm, we like to know if they're after our youth's souls."
"Huh, the translation spell keeps being weird about the word 'demon' and I think part of the issue is that some things match, but some are wrong... We can't take souls."
"Good to know! So what are you like, if you're not demons? It's a ways to Louis' tank."
"We have a word for ourselves," he says it, "and when I ask the translation for a translation it gives your word 'demon' as the best approximation, but not quite right. I am not sure how to explain our species, because... I don't think we are in the human world that we know of."
"Huh, I guess that's obvious. But explaining our species isn't that hard, just compare to what we remember about being human. We look like this, we can fly, we are fire resistant, we have this thing that makes us regenerate and look right. We have fetching horns and tails. Our species' magic is called empowering vices and it gives us a power in exchange of a drawback."
"Nice. No superstrength or anything, though?"
"Not without the right magic, no."
"We could be a bit stronger or even weaker, but not noticeable so. If you can carry us both then you are definitely stronger."
"Eh, I'm stronger than most people. Carrying you guys wouldn't even be pushing it unless you're made of degenerate neutronium."
Snort. "I have no idea what that is, but I am going to assume that we are not."
"So, what's the deal with this place, anyway? Is this all magic or something?"
"All of what? The buildings? Those are just made of bricks and glass and stuff."
"I was talking about how Morty called this place a 'weirdly sexy high school' and you have something that can turn people into slime monsters. But the buildings are kinda weird too."
"Oh. People turn into slime monsters sometimes when they manifest as mutants, I guess that's what he was talking about? That's not magic, that's just superpowers. Same with the weirdly sexy part. I don't know why the buildings would be weird to you, is your home dimension stuck in the Middle Ages or something?"
"I am not sure what a mutant is and I have no reference point to figure out what the Middle Ages are. Except as a period in history, I guess."
"Mutants are people with superpowers. Middle Ages: everything's made of wood and stone, there's no electricity or plumbing, everything generally kinda sucks."
"Hey! Our world does kinda suck," he says brightly. "It's war over this land or over that land. It's terrible."
"...Electricity is a thing, but I am not sure how it's relevant? Unless you meant something other than lightning bolts and electric magic."
"Pretty much everything here runs on electricity. It turns out if you put lightning in little wires and control it really well it can do things like light houses, cook food, record information, and play games."
