They find that unsatisfactory; they keep trying until somebody lands on English, does he speak English?

Yeah but he wants to learn all the other languages.

The demon who speaks English says the best way to do that is to conjure up the language section of the Library, and in the meantime if he wants to stick around in this part of Hell there's some neighborhood association rules, here's an English version of them.

"Okay, thank you." He will read those!

He is not supposed to make anything contiguous with someone else's structure without permission, nor anything ever in the middle of a thoroughfare. Making anything in the park and then leaving it there without permission from the Park Association is prohibited; the Park Association can be found inside of the really big tree in the park. The city observes quiet hours midnight-8am (UTC) out of courtesy for those who prefer to sleep. If you destroy somebody's stuff and they're not there to express other wishes you need to neatly finish the job, clear the debris if applicable, and put it back for them. There are some radio band use ordinances and a place to go for advice on compliance with those. Inhabiting the city constitutes agreement that the city council may issue binding arbitration if somebody complains about him.

...they think he's a demon! This is great! He bounces happily. The rules seem very reasonable and he is not going to break them on account of not being a demon. He wonders if he can cast Bella's bungalow spell discreetly enough that it looks like he is making it.

Well, he'll have to find someplace to put it first.

The demon who speaks English adds as an afterthought that there's a lady uptown who has always wanted to adopt a child ex-summoner, if that sounds like the sort of thing that might be useful?

"I already have two sets of parents! I have my mom and my dad but they're kind of incompetent and rule Tirion so they can't go on adventures with me, and then I have Bella and Rúmil who are actually good at it. But I would be glad to have some help!! I want a bungalow like Bella had in Tol Eressea and I don't see a place here I can put my bungalow!"

"Uh," says the demon, "if none of those people are demons you're not gonna have them here unless you get summoned and manage it then."

"Bella and Rúmil'll definitely summon me out as soon as they figure out I'm here and not at Space like I was going to be."

"You have some kinda spaceship accident?"

"No, I was just on my way there and then I came here instead."

The demon is skeptical, but shrugs. "Whatever. Welcome to Hell."

"Thank you! It's amazing! Do you know a place where I can put a bungalow?"

"Someplace nobody's using that's not in the street? I don't know off the top of my head."

"Okay!" And he walks off down the street.

It is full of demons. He attracts some attention for being visibly a child or possibly just nonwinged, but nobody stops him.

Eeeeeeeee this is so much fun! He can't give himself wings but with enough spell practice he could probably figure it out. Hell looks really ridiculous but he doesn't mind at all it's so interesting!! He stays on the lookout for open spots so he can magic himself a bungalow and everyone will think he is a demon eeeeeee!

The city's pretty dense. There isn't an empty lot for a while. Then he finds out a burned-out spot where someone has removed a house.

That will do. Bungalow?

Bungalow! Nobody pays much attention.

Well, they think they are not paying much attention to a demon so that's okay. He goes into his bungalow and runs to the windows and peers out and listens in on conversations in the streets.

They are talking about theater and the wing design regulations for an airspeed race and the physical properties of chalk.

He's not that good at the language yet. He sits and listens and echoes things aloud until he falls asleep, and in the morning he does it again, and by the next evening he is fluent enough to follow this discussion. (He has Allspeak. Allspeak is off, on principle.)

The demons within earshot of his bungalow are now talking about how pretty the Milky Way is supposed to be in person, and about music, and about a new restaurant.
