She offers her services to every lunar colony that will give her the time of day. Most of them accept. Cam is instrumental in most of what she does, but Adana summons a few angels to help integrate shiny new things with the older structures in place. The two angels that Cam meets are nice to Adana, but less so to him - he gets the cold shoulder and some pointed glares and insinuations, but nothing else comes of it besides that. Adana keeps the peace as well as she can, distracts all parties involved with things to do, and they carry on without any real incident.
While fixing things is something that she's happy to do, she wants things to be organized in such a way that they don't need her to keep functioning. She has Cam make several factories, specialized in maintenance materials. Then she sells the rights to use them to companies that she background checks as 'not idiots.' She undercuts what it would cost to have them built normally, accepts several commissions to make other factories for things like shuttles and polymer repair gel, and has Cam build those, too. Along with those, miniature black holes are created and sold, to give gravity to space stations and the like. Soon enough, she is rich.
Once she has money to play with it, she starts using it. She bribes several companies into making deals with one another, hires more staff to do her bidding, and then slowly expands. Disaster relief structures are made, funded by her business in services such as extranet ports and factories. She negotiates the disaster relief's neutrality to international laws, and then they get to helping lunar colonies that are having problems.
Meanwhile, she negotiates with Mars and its colonies to set up terraforming. It's slow going, there are a lot of separately governed colonies to get to play nice together, but she makes steady progress. They should be good for terraforming the planet within a year. She realizes that she could just grab Cam and go do it whenever she likes, with or without permission, but she isn't anonymous anymore.
She becomes known as a demon summoner. A very effective demon summoner. Soon it's common for people to look at her nervously when she walks into a room. She doesn't care, except to behave extremely nicely, and play nice with all laws that she can. No need to make people afraid of her or Cam, she's got time to be patient.
True to her word, the binding on Cam is loose and pretty flexible. She doesn't stop being nice to him or treating him like a person just because he is working for her. Actually, if anything, she's nicer - cheerier, happier, thanking him every time he makes her something useful. And there's usually something useful to make, too, because she's always doing something or working on various projects that are all leading towards one goal - make the solar community as nice a place to live as possible.
He thinks he is - maybe not literally as lucky to have met Adana as she is to have met him, considering that if he'd met the wrong summoner it would have been a mild disappointment and if she'd met the wrong demon in the relevant conditions she'd be in lousy shape - but certainly very lucky for him too.
He makes things and naps and snuggles his summoner and flips angels the bird when they're rude to him without much real heat.
When he has been around full time for a few weeks and there's some downtime -
"Hey, Adana?"
"Some demons think it's funny. I mostly haven't shared the information because nobody but you tended to let me talk, but the reason I hesitated to mention it to you when there was a moment is because - consider the situation when it ever actually comes up. Some mortal is desperate enough to offer their soul, or leave the price wide open. Some demon is enough of a dick to be amused by the prospect of 'taking' it. Now assume it's common knowledge that there's no such commodity. This doesn't undo desperation or dickishness one bit, but..."
"Dead people," he laughs. "This one I don't know why some fairy or angel hasn't fessed up, but my guess is that you're getting angels and fairies who are deeply uncurious people and don't know - it would be easily possible to miss the information - or who don't think this tidbit would be interesting. It goes by assorted names, at least in Hell; my favorite is 'Limbo'. It's not terrible but it's not great either."
"Limbo-ites don't get any magic powers, and you can't summon them - well, if you can I don't know about how to do it, anyway. And Limbo is natively dramatically less interesting than Fairyland. It's basically flat earth extending infinitely, about a gee of gravity, and besides dead people - who are about as indestructible as daeva, but otherwise human - there's not much stuff. Specifically, the going theory is that when someone appears in Limbo they get one thing, which is whatever tops their personal list of 'things an afterlife would be incomplete without' and is not itself a person. Opinions vary on whether you can get a copy of a still-living animal. So you get your childhood dog or an ice skating rink complete with rental skates or a pond or a burger joint that stocks itself obligingly with burger fixings. But there's only one such thing per person, and they can't move or edit them either, so they have extremely haphazard sorts of settlements built out of incidentals."
"That sounds incredibly annoying. I think I like Hell's haphazard - stuff all over everywhere thing more. I mean, that sounds nice in some senses but also - what about houses? There can't be enough for everyone, if people only get one thing. Not everyone's house is at the top of their list."
"Here's where we depart from 'secrets of the universe' and enter 'mostly speculation'. Although I'm going to mention as an aside that my parents are both long dead by now, were the only relevant humans, and I have managed to get letters to the both of them via concordances on a few occasions - fairies are shit with mail but sometimes something gets through. I think that all summoners, on death, become some kind of daeva. I don't remember getting to pick, but the consistency of personalities - limited, but present - within types suggests to me that it's about some kind of personal sympathy with the magic. I'd peg you for an angel-to-be. But the overwhelming majority of daeva just appear out of nowhere with wings already stuck on - ninety-nine percent of them, at a guess, maybe less overwhelming among the ones who take summons. Your one angel might really have a sister who is also an angel but I'd still bet on 'they adopted each other' to explain them. And a lot of the dead summoners are a hell of a lot older than me and keep less thorough diary entries. They might not remember."
"... Okay. Okay, as far as final fates go, becoming a daeva is one of the better ones. I can - I can handle that one."
She laughs, a little. "An angel-to-be? What - what makes you think that? I could end up with you in Hell, we could cover up the tacky gold plane together."
"All right, I liked angels fine when I was a human. The cosmetics aren't intrinsic to being a demon, by the by, the ones of us who land with human histories have to add wings on purpose. The natively demonic start out with them. I considered doing feathery wings just to screw with people but I decided against it."
"Angels have it much easier in that department, they can just turn theirs into their cloud-fluff if they feel like it, easy as pie. But I cleverly anticipated this problem and right near the joins there's about a quarter inch with no pain nerves. It'll be sort of gross but not intolerable. And there's a limit to how much it would hurt even if I hadn't thought ahead. The indestructibility relaxes around deliberate body modification but there's still a cap on how much discomfort I can experience."
"I'm fine. Waking up in Hell was disorienting, but it was fundamentally good news. I always wanted power and immortality. And a little asking around told me that my parents were going to be fine too, if somewhat less comfortably accommodated. And I got a few things done before I died."
"I think it's about the magic, not about the culture that's accreted around the magic. And it's kind of hard to put into words. But you seem like you're best suited to a changing power where you take something that exists and make it into something that also exists, but differently."
"I could've rationalized it if I'd woken up an angel, but best suited - yeah. Building things myself from nothing. In theory angels could do the big grandiose stuff, just give them enough cloud or a giant rock or something, but demon power invites massive this-is-not-good-enough-so-let's-make-so
"It's regular but doesn't match up to mortal sidereal time, but approximately every twelve years per pair of worlds. Hell gets Fairyland and Limbo on approximately opposite schedules, so I get to try collecting and sending letters and packages to my parents every six years ish and actually succeed every ten on average."
"The revelation of limbo does kind of suggest the revelation about souls, so maybe be a little discreet with it. Unless you determine that you can in fact resurrect the dead, in which case I support going completely nuts with it right away and getting lots of summoner-hours on the project."
"Right, I wouldn't ask on a public extranet forum or something, I would pretend to be asking about summoning fairies or something and then use that in the case of Limbo. Unless I actually manage it, in which case, I will happily cause lots and lots of tearful or stoic reunions."
"I am not planning to take that long. I am planning to make quite a lot of progress and live to be two hundred, and shortly after I die for my kids to immediately summon me back so I can keep up the good work. But obviously that might not work, so I will just go as fast as humanly possible."
"I'm fine. I like being busy. The last hundred and fifty years of my life have been mostly vacation. I have learned six demonic languages the long way and studied a lot of subjects and learned to fly and learned to swim with wings on - second thing is harder - and read many books and now I get to be busy."
"Fair enough! I am probably a good summoner for you, then, because I also like to be busy. With fifty thousand projects going on concurrently that I can bounce between at will. Let me know if you want to go back to being on vacation, I will still get things done without you, just a bit more slowly."
She notices the way he's looking at her. Adana isn't used to attention from the opposite sex and doesn't know what's going on. "... Why are you looking at me like that, do I have something on my face? Or in my teeth? Am I secretly hideous and you just figured it out now?"
"Dads don't count, they always tell their daughters that they are beautiful. Makeup salespeople also don't count, because they are trying to sell something. Met a person with taste?" Adana giggles more, looking down. "I mean - good looks are in the eye of the beholder? So they can have taste and not think I'm beautiful."
"I assure you, if you resummon me in the future and you're all business and you tell me that the deal is that I can have one kiss if I make you a sandwich every day for the next decade or anything weird like that I will 'no summoner' you without hesitation. I mean, then I might be unhappy and eat a pint of ice cream, but you can't actually make me do arbitrary things."
She scoots and moves to embrace him. "You're smart, funny, and you seem to want the same things I want with lovely new ideas to get there. You were put in the situation where you could do - basically anything you wanted, and you decide to hug and comfort me, and I'm not immune to that sort of thing. It was incredibly kind of you."
"It is a little odd. I don't think I'd have kept any demon around long enough to make a space station without going 'but why stop there?' and terraforming - well, Mars. Not that I fault you for your caution, you had more background noise about what demons are like in your history than I did."
"I might have terraformed Mars rather than gone with the space station if there was no one actually on Mars, but I was also under a time constraint." She shrugs. "There are less problems making a space station that benignly orbits Earth than with trying to terraform Venus instead. It's an option, I suppose, but I think Venus would require an angel, instead of a demon."
"Actually, now that I think of it - it is a good idea to find some other summoners to promise to summon the both of us back once I do eventually die. That way, we're both not forced into retirement and can actually see each other."
"I trust some people that could become summoners, I mean there's no reason that both my dad and my brother shouldn't learn how to summon both of us in case something terrible happens. Dad would be more reliable about it, of the two of them. But summoners that I happen to know right now, no."
"There are schools for that kind of thing, but there's also still some informal stuff where if a person who wants to grow up to be a summoner they can go find someone who is one and learn that way. I think there are forums on the extranet for that kind of thing. It's possible that now that I'm famous, some precocious kid will run up to me and ask me to teach them. I'm not entirely sure, I wasn't an apprentice, most of what I know is from books."
"... If you want to not be monogamous, let me know, I know my brother's got a - multi-person relationship going on. Or something. I'm not sure, really, but it involves multiple people. Not the kind of thing I personally go for, but uh... I'm not judgmental. If that's what you like."
Adana nods. "Makes sense. And if all goes as planned, that won't be an issue, we get to bounce around being summoned by helpful apprentices or family members. But if it is - I'm okay with it. Just um - as long as I'm not..." Pause, squirm. "A notch on a belt? Essentially?"
"Are you one of those people who objects to serving purposes like that secondarily provided I am also personally fond of you and consider your interests important? I'm good at a lot of things but none of them is - fooling myself into believing the list of reasons I might want to do a thing is shorter than it really is."
"Most likely, yes," she agrees. "There was a bit of an argument about if I'd gotten an angel to doctor it myself, actually. That was about the only thing that kept them from immediately saying, 'Yup, guilty.' I think she also tried to argue that you'd made the killswitch, but everybody knows that you don't unbind demons." She winks. "So how could you have possibly managed that?"
"Right. That's essentially my logic on the matter. I am having trouble imagining a situation where I would willingly destroy people that utterly, honestly. Send them to Limbo, maybe, if I had no other option, but actually ending people I don't think I'm capable of. It's more likely that I'd just - lock them up, make sure they have basic necessities, throw away the key and then ignore them."
She nuzzles him, after kissing has gone on a while. "So, while I am thinking of things that you might want - any places from human-hood that you would like to revisit? I can tolerate Earth-gravity if it means you get to see your childhood home again or something."
"My parents divorced when I was a baby. I spent most of my time with my mom, but I visited Charlie summers and moved in with him when I was seventeen because Renée moved to Jacksonville to be with her second husband. So there's a house in Forks, Washington and a house in Phoenix, Arizona."
"I can tell you stuff if you want. My full name's Campbell Mark Swan, which will help you narrow it down if you want to mail me something in Hell. I was an only child, I did not know there was such a thing as magic till I was seventeen - what else do you want to know?"
"Does my name sound that weird, really? Do kids not get named Campbell or Cameron or anything anymore? I liked - still like - reading and introspection and making excessively ambitious plans. I spent a lot of time being precociously responsible because my Renée's a scatterbrain, I cooked when I was at Charlie's because he's almost unrealistically bad at it. I did well in school, math was my worst but mostly because I didn't care about it and I'm fine at enough to get along in keeping up with advances in science nowadays. I wasn't really popular, though, didn't put enough effort into it, I had people I'd talk to and I'd have reasonably well-attended birthday parties until I was too old to have them at pizza places but nobody I was upset to move away from. And I always liked really old literary fiction - stuff that was old even then. Shakespeare, Austen, Dickens, occasional foreign novel, stuff like that."
"I always went by the 'Cam' part, yeah, I don't remember getting called Campbell except when Renée was really mad or it was the first day of school and I don't use the whole thing at all since dying. I think I would've liked you if we'd met in school, although who knows, maybe it wouldn't have shown off our potential to much effect if all we ever did around each other was recite oral reports on Stonehenge and give everybody in class Valentine's day cards because you can't leave anyone out."
"It's possible! Or Zane might have scared you off, he did that occasionally with people. I never did the give everybody in class Valentine's day cards thing, I basically just stayed out of it and accepted candy offerings. Because it's candy. I lent out notes a lot, though, so we might have met that way, though I doubt that would do anything to show my actual personality. So back to square one, we've got no idea."
"Not if I explain things first! He has been known to actually listen to me when I explain things. I don't even know how he would threaten you, though. You're indestructible. I guess he could mildly inconvenience you for a little while, but um - you're a demon. You'd pretty handily win."
"I'm indestructible, not invulnerable. Assuming you don't want me to fight back since he's your brother and stuff he could give me an unpleasant time. It's sort of like attacking a watermelon with a plastic fork - it will be challenging to get anywhere but the watermelon is still scratchable."
"I think you have more hangups about that than I do. I mean, when people do not treat me like a person I am quietly judgmental, but I'm much more concerned with how much this inhibits my ability to accomplish things, or I wouldn't ever answer summons and then where would you be?"
"I never got the chance, anyway. String of ten shifts cooperating with an angel to make a subway system, string of four spaced a few years apart helping some real estate developer make apartment buildings, and if you want to hear about the other multiple-summons case I need to know how much you wanna hear about my sexual history."
"I built this nice girl's house, and when I was all done and she handed over my compilation of obscure indie music, she told me that if she summoned me again it would probably be because she wanted to do me. She did. I went. Like once a week for a few months. I'm pretty sure she had obtained 'how to safely have sex with a demon' instructions from the internet or something."
Off they go to Mars.
Cam takes a while giving it a large amount of breathable atmosphere first. It will be very windy on Mars as the air spreads out. The angels have nothing to do but watch Cam suspiciously as he pours out air and reads a book.
He fills the depressions in the planet that haven't been peppered with dome cities with fresh water and some appropriate microorganisms and plants.
Then he get started on non-aquatic plants, hopping from place to place by shuttle and making swathes of topsoil and planting them with temperature-compatible flora that don't need bees or anything, all ready to go to seed. They'll be importing the animals they want.
It takes a couple of weeks to have it done to his satisfaction.
And then, with the angels off his back because he's officially done, he sneaks a moment in a spot that he didn't plant and then goes and finds Adana.
Adana is having a conversation with the summoner who summoned two of the angels. It's about little tweaks that might need to be made as the planet settles in to its terraformed status.
"It might need a few adjustments, but it shouldn't change dramatically," says Adana. "Just import the animals in a reasonable amount of time and it'll stabilize itself pretty well."
Her companion nods. "Fair. You do good work, I haven't seen a demon used so expertly."
"... Thank you," says Adana, after a pause.
"You're welcome!" says the summoner brightly. "Just wait, you'll be writing books on how to safely summon demons in a year or two, we can probably manage some other planets, too, without the annoying runaround that Mars required."
Adana nods. "Hopefully. There are lots of helpful things that demons can do." She sees Cam, and smiles a bit. "Excuse me, please, I think he needs me."
"Sure," agrees the companion. "Gotta pay the dues, and all. Not going to ask what you're paying." Wink.
"... Yes," says Adana, awkwardly, and then she heads over to Cam. "Hello! I heard that everything's done!"
He leads her to the nearest way out of the dome and into the fresh breezes of Mars and into the shuttle he was using to hop around from point to point.
He flies her to a certain spot well out of the way.
He lands by it and leads her into -
a garden.
The plants here probably aren't going to hold up in the relative chill of Mars for that long, but cold can do a reasonable job of preserving flowers, up to a point, and this point has not yet been passed. It is full of flowers. Flowers piled on and twining around each other, forming archways, shaped into a gazebo; clover almost choked with its own blossoms underfoot; if there's underlying structure of some non-living kind, it's been thoroughly buried in blossoms.
In the gazebo hangs (from flowered vines) a deep and cozy-looking swinging couch, because he didn't want to imply the presumption of a bed, and the couch is the only thing not made of flowers in the place. Before it is a (floral) table, and on this table is a lot of covered dishes that look suspiciously like they may contain lunch.
"Did I go overboard with the flowers?" Cam wonders brightly.
They return to Adana's space station, shortly after. She's got managing of things to do. Cam is entirely welcome to help! Or just be around and cheer her up with his presence. She can do work on a tablet while snuggled up in his arms and wings, if it doesn't bother him.
Less than a week later, it's discovered that some of the weather patterns on Mars are a little weird - it's not raining as much as it should, and some of the plants are having trouble because of it. Adana is specifically addressed to fix it.
"Want to?" she asks Cam, when she learns about it.
"Pre-made the binding?" asks the summoner.
"Yup!" says Adana, brightly.
The summoner is a little suspicious of this fact - she tilts her head, and uses her magic to check -
- then she hisses.
"That is the loosest binding I've ever seen in my life, are you trying to get everyone killed?!"
"Useful. For your purposes," says the summoner. "... Put him back. Unsummon him, right now. Before he gets loose and puts a black hole instead of water!"
"Wha- no, it's fine -"
The summoner looks at her. "I'm sorry about this. I really am. You seem like a good kid. Put him back, right now."
"Look, I know what I'm do-"
"You really don't," says her companion. "You really, really don't. I'm sorry about this, so very sorry, but you're a danger. He can't be here with that loose of a binding, and you won't put him back."
"What? No - shit, Cam!" shrieks Adana.
There is the sound of a gunshot -
- and then Cam is back in Hell.
Maybe they put her in prison and she has nothing to draw with.
And hasn't been allowed to talk to her dad, or her brother, to suggest that they fetch him up.
Maybe.
He starts writing letters to send next time there's a concordance anyway. And in case he was wrong about what she'd be he puts a pointer to his residence in the major cities of Hell.
