"Hell is comfortable, yet tacky," says Cam, unlocking his door and scanning the furniture critically. "Since we can all make anything and have no magical way to get rid of it. The discovery of black holes improved things, but there are still a few traditional lakes of fire around, and by then most of the cities had already been built on an enormous plane of solid gold that somebody had to think was a good idea for several sustained weeks, or convince several friends of same, to complete."
"Nope, sorry. The cities aren't made of gold, anyway, just the underlying surface." Cam puts sheets on the bed, adds a pillow and a duvet, sets down his tablet on the desk, and attempts to open the window."
The windows absolutely open. It's creaky and the paint's not enthusiastic about the idea, but the bottom half is willing to rise, at least.
"I am very disappointed in your cities' collective naming committees," Emma says, mock sadly. "Are there a lot of cities? ...Are there a lot of demons?"
She peers around the apartment, watching in fascination as bedclothes appear. "Did you want to keep the furniture? Some of the dorms have basements, I bet you could stash this stuff somewhere if you wanna replace it."
"There are lots of demons, not as many as there are humans in my time though, something like three billion of us, slowly increasing as new ones pop in. Plane of gold has sixteen good-size cities on it and a bunch of little ones and plenty of demons living by themselves or with a few friends. There are some farther-away planets and personal black holes; I live above, not on, the plane. There are dozens of demon languages and dialects of same, too, I have only learned six, and I would replace the furniture but I'm not sure how long to expect to be here and don't know of a good way to dispose of it after."
"New demons... pop in?" she asks, confused. "The idea of a personal black hole is kinda adorable. And anything that even kinda works in a dorm room will be super easy. Free furniture, college students. I could email some of the dorm lists but I mean, as long as you could get it to an elevator I've definitely seen people just leave things outside with notes saying 'free'."
"Okay then. Furniture replacement is go if there's a place to stash what's here already, then. And yes, new demons pop in, daeva of any kind can't reproduce."
That was not what Emma was thinking at all and she will now be slightly flustered. "Um, I meant like, where do they pop from? Can you pop back? Is it like... in a particular place, or random? Could there secretly be a hundred million more demons just really really far away from the-" snerk "-plane of gold?"
"Oh, we appear near other demons, more or less. We think, anyway, but there could be another cluster an octillion miles away that nobody knows about. Most demons don't seem to pop from anywhere. They just start existing."
"If most just exist, what about the rest?" She inspects the room. None of the furniture is terribly heavy, or too large, but it's a little awkwardly bulky. The two of them could move things by hand, but it might be time consuming. "Do you want to conjure... I dunno, a cart or something? Or I can ask a couple of my friends to help." She rolls her eyes fondly. "They can be bribed with pizza."
"Okay, little folding cart for you it is." Cam makes a little folding cart and starts stacking mediocre dorm furniture on it.
Emma is not particularly strong and Cam has a few inches on her, but she is used to dorm furniture by now. Helping ensues. It will take a couple trips to the basement, but the elevator is close and they have a folding cart and it's not much of a hassle. The basement's small, but not close to full; short term residents don't have much in storage. There is no shortage of places to put mediocre dorm furniture.
"You want to know where not-most demons come from?"
"Well, humans back home don't know, unless someone spilled the beans and I didn't hear about it, but it might be relevant to you, and this is a different world. But kindly don't go telling everybody until I've thought about it some more. Some of us daeva are dead summoners. If this world now works on afterlife rules like my world does, you will now be some kind of daeva after you die."
"Well, if your world now works on those rules, it's much better than the alternative - and off the top of my head I'd peg you for a fairy, not a demon."
She has no idea what her world's alternative is, but that means his world's 'will show up as a living being' is certainly much better than '???'
"Well, no, Fairyland's different from Hell in addition to fairy magic being different from demon magic. Fairyland's more interesting all by itself. I think but cannot be sure that it's about what kind of magic suits you best."
"I've never been to Fairyland. I have seen pictures of the landscapes, it's very pretty in a lushly sylvan kind of way, but have never heard rumor of an El Dorado."
"I like forests," she says wistfully, then sobers. "Thanks for telling me. It would have been kinda a shock." She looks at her pocket, which still holds the floating pencil for earlier. "Uh, mostly. The telekinesis thing I guess would be similar." She considers. "Are your 'parlor tricks' similar enough that people have practice, do you think? You said there's some telekinesis." Faint smile. "Maybe I'd just be weird and super competent."
"There is extremely tiny parlor trick telekinesis. It is slow, requires a lot of concentration, allows next to no precision, and unless you're preposterously good at it won't work over distances greater than an inch. Fairies can move pretty much anything however they want. I don't think practice makes much difference."
