"Oddly enough," says Cam, "trim my fingernails." He produces a nail scissor out of nowhere. He attempts to trim his fingernails. "Hurrah," he says, when the scissor doesn't get anywhere.

"...you have magic to make your fingernails untrimmable?"

"I mean, I mostly use it to do things like 'be comfortable with the risk that I will accidentally appear in a star' and stuff like that, but yes. I'm indestructible. I get to decide what things count as destruction." He closes the scissor again, gets the nail cut off, catches the sliver, incinerates it right in his palm, insta-heals the small burn this leaves. "And that means that if I make a copy of my computer and it doesn't work because the chip in my head corresponding to it is still broken, I can melt the chip and replace it without melting my brain."

"I want that!"

"You can in fact get indestructibility magicked on once we can get to everybody else! Not the same way I have it - getting it the way I have it involves dying in a way Elves do not do and possibly also that you die in a specific world - but the indestructibility part the spellbinders in Hex have finagled a la carte."

"Cool!!! Spellbinders? Hex? How?"

"I will get there. Lot of worlds to cover."

"Maybe we should go over Ardas in - chronological order, or something. Like, it sounds like you know more or less what mine was like until I got there, so I tell you what happened when I got there and then you tell me what it would have been like if I hadn't and then whoever got there next did thus and such but if they hadn't then - and so on?"

"I like this idea. Report first, though." He conjures a computer. It won't boot. He frowns at it, and then a minute later it goes on. "Did have to replace the chip, that'll be wickedly inconvenient for anybody destructible who comes through..." He starts writing.

He waits patiently for all of five seconds and then starts bouncing in thirty-foot arcs around the surrounding area.

"...oh my god," whispers Cam.

Boots giggles.

T'Mir chooses this occasion to show up. "Hello."

"Hey, be with you in a second, powers of infosec-hazard conjuration will surely be waiting for my writeup of what the heck."

So the girl Bells wait, and when he seems done: "So what are you exactly?"

"My translation magic glitched on the word in Materia, so, like, don't freak out, but I'm a demon."

"...you really wanna render that as, like, anything else."

"So I'm told. 'Maker' is fine."

"Maker? Of what sort of things?"

"Not antimatter, nothing magic, I have to have like two-sevenths of a clue about what it is."

"...cool."

"And we went to all this trouble building the city!"

"I wanna be a demon. The problem is that my kind of Elf can't be a demon? Why not? If there's magic that can make us indestructible has anyone tried magic that can make us into the kind of thing that can be a demon?"

Cam pulls up a map of the multiverse. "So, demons when we are at home live here. There are two other kinds of daeva with different powers, angels or changers, fairies or movers." Point point point. "The set of three worlds is adjacent to my home world, Revelation, and also to Space Arda, which is a variant Arda which is in space. Revelation has humans in it, that's it. Humans from Revelation who die appear in Limbo," point, "by default. Humans - or Dwarves - who die in Space Arda don't; Limbo is not adjacent to Space Arda. However, if a human or Dwarf from either Revelation or Space Arda summons at least one of any kind of daeva, then instead when they die they become a daeva themselves, not necessarily the same kind, it seems to be based on personality affinity with the magic but we're not sure. Space Elves in Space Arda are immortal differently from Elves from Flat Ardas, but they're still not gone when they're gone. So far none of them have managed to become any kind of daeva. We also don't know if people from non-adjacent worlds can become daeva - summoning only works adjacent to the daeva worlds, but it will work for visitors, but so far none of our visitor summoner test subjects have died, very inconvenient."

"So I need magic to turn me into a human? I can invent that!"
