He feels an open summons and lets it grab him -
It's late at night and Jarvis is bored and running diagnostics on his holographic display. Geometric figures in two and three dimensions, text, minimum possible distance from obstacles - tables, walls, ceiling, floor...
Aaaaand he's totally loose, but the angel will probably be spooked if she notices that, to say nothing of the sloppy summoner. He rocks back on his heels, looks around, doesn't say anything just yet.
Then she spots the demon and she flinches. She has encountered a demon. Once. "Summoner?" she says, looking at the demon in absolutely genuine terror. "Summoner please tell me the demon is bound better than I am."
The summoner does not respond.
Apart from some moving coloured lights that vanished almost as soon as the daeva appeared, the room is poorly illuminated - only one in five of the fluorescent lights in the ceiling are lit. The result is spooky, but it's enough to tell that the two daeva are the only people present. It's a very large room; the far wall is only dimly visible from where the daeva stand, in an empty space on the bare concrete floor, between some haphazardly arranged tables laden with assorted electronic components and some cars lined up near the only clearly visible exit. There are no windows. It's pretty clearly a garage/basement of some kind.
Well, he's not gonna attack the angel. Far as he's concerned she doesn't need to know he's loose at all if it would upset her.
He sits on the ground.
The angel looks at the demon suspiciously. He's not obviously doing anything harmful, and it seems like he's actually bound, but - still. Where is his circle? Adana's was made out of light, and it's gone now, is his the same?
"Summoner, please answer me, this is important! If there is a rogue demon on the loose I need to know, I am the closest daeva nearby to stop him if he starts trying to kill people," says Adana, concerned and a tinge of fear leaking into her voice. "I won't be angry, just - please. I am worried about the safety of those around me!"
If the summoner even cares, what kind of terrible summoner summons two daeva and then abandons them in a creepy dark basement with vintage cars?
Cam continues to sit harmlessly on the floor. His tail swishes against the floor a little. But he isn't making anything, isn't saying anything, is looking at her with mild curiosity and nothing more.
"Lights up, c'mon," he yawns. "What am I looking at here." The rest of the ceiling lights come alive, illuminating the room - yep, definitely a combination basement/underground garage. He peers at Adana and Cam. He stops.
"...Does somebody wanna tell me why there's winged people in my basement? I didn't ask for winged people in my basement," he says.
"Someone summoned us," explains Adana. "I am unbound but I - think the demon's bound. Do you know who would randomly summon two daeva in your basement and then abandon them? This is quite dangerous and irresponsible, I am extremely concerned."
"... Winged people in your basement. We are daeva? I'm an angel, he's a demon, there are also fairies but we seem to be missing one of those in our basement menagerie. There are others and we all do different types of magic?" She sounds like he should know this and that she's confused that he doesn't.
"Iiiii think we are maybe talking at cross purposes a little bit here," he says. "Because you seem to think all of this should be obvious, and it's definitely not obvious, and you just randomly appeared in my basement. I'm thinking interdimensional shenanigans."
For a few seconds, Adana stares. "Okay," she says. "Um. Where I come from there are normal humans and then there are daeva. Three types - fairies, angels, and demons. Any human, ever, can summon one of those three, and when they summon them they can also bind them so they don't - go on a rampage or steal souls or -" She cuts herself off, abruptly, and scrunches up her eyes. "- other terrible things. Angels are reasonably nice. Fairies are occasionally jerks but you can pay them off easy and it's not like they can do large-scale cataclysms or anything. But I have met a demon before and he was very much not nice. Therefore, I am extremely concerned. Why, what's it like here?"
Oh. She's not just racist.
Poor angel.
Cam is a quiet quiet listening demon with his wings folded behind him and his tail still.
"Steal souls?" the pajama'd boy repeats. "That's, like, worrying. I'm worried. - Okay so around here 'demon' is not a subcategory of any kind of a thing, it's a catchall for, like, anybody who's not human, there's something like three thousand species of demon and a bunch of them are pretty nasty but some of them are fine. And I guess some kinds of demon can be summoned, but it's pretty different depending on the kind, and not everybody can do all of 'em, I don't even know what-all you need for some of that shit because I'm not a freaking demonologist." He rubs his face and yawns again. "Also it's three in the morning, have I mentioned it's three in the morning? It's three in the morning."
Pause. "I'm sorry it's three in the morning, will you help me find the summoner so we can get an explanation for why we are in your basement at three in the morning?"
"A summoner can summon things, and upon summoning give - constraints to the summonee. But they can't change them after they're set, it has to be when the daeva's summoned. Bindings can be broken after but never replaced or changed. Summoners also get some very minor personal magic, but it's so slow, small scale, and difficult that in just about any situation it's not worth it. Summoning works by drawing out circles to fit certain categories with what you're summoning written around it. Mine was made in light, light works but it's not really common in comparison to like - markers. Or even crayons, actually. Someone summoned me in crayons once, that was a strange day."
"Does... That narrow down who the summoner is? At all?"
"It means that I'm pretty sure it was an accident," he says. "What happens if it was an accident?"
She glances at Cam. "Demons make things. Anything in the world."
Even bound and gagged Cam would be able to make things that didn't affect anything outside his circle. He makes a sugar-glass that he'll be able to eat later, full of apple juice. Lifts it, makes the facial expression associated with saying "cheers" even though he doesn't actually say the word, sips.
