There appears an outsider. He looks human, as they go, only wings and tail betraying the difference, though the indigo fabric of his pants is exotic and his shoes if anything moreso. "- good morning."

....Detect Magic. 

Yes! Lots! So much! He is absolutely blinding with some kind of abjuration-transmutation mess! And then he throws a little high-octane conjuration on there too! If Élie could still see physical objects clearly he would notice that the conjuration is accompanying the appearance of a bite of grilled cheese. "Didn't anyone ever tell you that you shouldn't draw on the floor?"

Oww he's seeing stars. Summoning circles are basically just protective circles drawn inside-out, so it's not outside the realm of plausibility he could have grabbed something, but there's no way he's able to bind wait what was that. 

" – Can you do that again, the conjuration, I want to look more closely." 

"At, what, the sandwich? I'm trying to give you vital safety advice about not summoning unbound demons and you want me to make you a sandwich?"

"If you're a demon then I couldn't have been the one to summon you, I'm not powerful enough. There's another wizard about and you're their problem, or you're really unbound and you're about to eat me or whatever else it is unbound demons do, either way there's nothing I can do to stop it, and if I only have a few minutes left to live I want to know how that spell works." 

"I have a sandwich, I'm not about to eat y-

"- this isn't French," remarks Cam thoughtfully. "It has a certain Frenchness but it is not French. Huh. Where the fuck am I?"

"City of Isarn, in the nation of Galt, on the planet Golarion – our star system might have a disambiguating name but if it does I don't know it – on the Prime Material Plane. If you claim you've never been summoned here before, how are you knowingly speaking Galtan?" 

"Well, I get all my summoner's languages when I show up, and my expectation is that's you based on you drawing on the floor and nobody else being here but it could theoretically be someone else, do you want to check if all the new languages I've got match yours?" He pops his bit of grilled cheese into his mouth.

"...how sure are you that you're a demon? The Abyss is infinite so I suppose anything could be going on there, but that's not a feature of any of them that I've ever heard of."

Élie has decided he's just not thinking about how he's almost certainly about to die! He's been almost certainly about to die enough times to know that dwelling on it doesn't improve the experience.

"I'm not at all sure that I am landing on the correct terminology because I didn't know this language existed five minutes ago, it feels like the right word but sometimes that's barking up completely the wrong tree. I'm an apsel?"

"I've never heard of apsels, but that doesn't mean much. I speak Galtan Taldane and Chelish Taldane and passable infernal, and I can get by in Kelish and Draconic and Azlanti – at least I think so, not having spoken to any dragons or Azlanti people. Is telling you the names of the languages enough to identify them or should I say a short sentence in each? I still want to see that conjuration thing again. Can you make stone or minerals? That would be a different spell for us but I have a suspicion it isn't for you." 

"I can make whatever I want." He makes a bit of pumice, tosses it underhand to his summoner. "I think I've got all those, though I've only got literacy in the last few."

If the thing he's doing is different, Detect Magic isn't picking up on it. And Élie's eyes are starting to hurt. 

"That doesn't necessarily mean I'm your summoner, they're all reasonably common languages for wizards here to know, but at least it's suggestive. How does summoning apsels work? The kinds of magic users who can summon apsels of roughly your capabilities, what else can they do?  ...Do apsels vary in their capabilities, and if so, how widely? What other kinds of magic can you do? Do you know what planets you're ordinarily summoned to and if they're in the prime material? Can you describe your native plane? How many times a day can you create things? Are you limited by total mass or something else? How long do they last?" 

Tailswish. "Apsels all have the same basic abilities but different skills. There are two other kinds of what we call 'daeva', who have some of the same underlying features but different active powers. All I can do is make things but it's a remarkably flexible sort of making things. No usage limit. I am limited in volume per time, and range, but both limits are very very big. They last indefinitely, once I make something it's a normal thing."

Is the pumice visibly magical?

Not in the least. It could have been dug up from the ground. (And carved into a perfect sphere.)

Then Élie is going to very abruptly start sobbing! 

"- geez, dude, are you okay -"

That's an interesting question. Objectively, Élie doesn't think he's ever been okay, and he's closer to being okay in this moment than he's ever been before, because if the apsel is telling the truth – if the apsel is telling the truth, and he's not hallucinating, and this isn't some confusing attempt at espionage, and there aren't other apsels popping up all over Golarion right at this moment, and if he can convince it their revolution is worth a few minutes of its time – then the war is over and Galt has won. 

He takes thirty seconds to pull himself together. 

"I will be. I think everything will be. Are you, uh, broadly in favor of the flourishing of sapient beings?" 

"Sounds awesome, I love the flourishing of sapient beings, why, are you having a famine or something?"

"We are having a revolution against a tyranny ruled by the servants of an evil god for the purpose of condemning as many of their subjects as possible to eternal torture." 

"- that's both incredibly fucked up and perhaps difficult for me to verify!"

"You said you could create anything, right? None of this is secret. We have royal decrees, newspapers, history textbooks, sermons, the Asmodean holy book, reports on public executions, and I'm sure the secret police take notes. 

...We do also have a famine but that's mostly because of the war. Galt used to be the bread-basket of Cheliax." 

"- well, how about I get underway on food stuff while I read royal decrees - do they literally say things like 'we, the servants of an evil god, want all of you guys to be condemned to eternal torture', that has to be terrible PR even if it's true -"
