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.
Herod notes the rules of etiquette, but does not immediately puts a towel on. It didn't sound urgent and he is busy getting this shave right.
They do put on towels before leaving. The plan is to stay in their bedroom - while copying slash memorizing slash categorizing their spellbook - until it's a reasonable hour.
In that case they will put on their fancy new clothes (even Herod likes the prospect, Gav only teases him a little about it). And then they will leave their room. Is everyone just going straight to get breakfast?
"Yes, thank you. And we are still getting used to things, yeah. ...Ariel described our world as medieval."
The demons follow. "Thanks for letting us know. We haven't run into too much trouble yet. Mostly because this place is like some bizarre non-magical magical paradise. Honestly, I kinda want to thank Morty for bringing us here, but he is straight."
"Oh, uh, I'm a Warper, so I manipulate one of the fundamental forces of the universe? In my case and Morty's case, that's luck. The problem is that when you get two probability warpers in the same room, their powers kind of... start fighting each other? Because you can't both be luckier than the other. So the side effect of this is that really weird shit starts happening when you get two probability warpers together, and that's one of the reasons I can't be friends with him. The other reason is that he has Diedrick's Syndrome, which gives him manic episodes and fucks with his emotional regulation, and I'm a Class-3 Rager, which means that when I get really angry I won't stop fighting until I'm down or everybody else is, and I get more powerful when I'm raging. Because ordinarily I'm a midlevel Esper/Mage/Warper, but when I'm raging I'm one of the biggest threats on campus. So if he got all 'you pathetic worm' at me, I might end up turning him into a slime mold."
"Yikes! I guess you could become pen pals, but as much Gav feels like praising him, I don't think it's worth the risk. On either end."
"Sounds like a plan. See you in a bit."
They go collect breakfast.
They are really baffled that this place has different menus for different kinds of the day. Oh, well, they don't need to try everything in a day. They go find the Hemitheoi.
The Hemitheoi are sitting around the table and chatting. "Honestly," says a black girl, "I don't know how you got your parents to let you get your tongues pierced. My mom would kill me."
Two identical boys shrug in unison. "Dad couldn't care less," says one, revealing a bright silver tongue stud.
"And Mom thinks she's cool for letting us," says the other, whose tongue stud is a softly glowing gold.
"Parents are so annoying," Alex sighs. Everyone else at the table nods, except for the boy sitting next to him, who looks mildly offended.
"I only remember one out of four of my parents, but I do agree that they can get annoying."
