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.
"The lakes of fire, then? The mini black holes? Give me some tourist attractions to look forward to, if I get corrupted to demon-hood! Besides the company, I mean."
"There are lakes of fire, and mini black holes, and truly heroic efforts to make gardens and wildernesses in the absence of natural light."
"Ooo. Do they use some sort of artificial light? I would think someone would think to make a sun, if you've got eternity to make it."
"There are a few suns but they're not that near the tacky plane of gold. The airspace right above said tacky plane is full of demons who want to be within commuting distance of the plane and would object to a sun appearing a fraction of an astronomical unit away."
"Ahh. So no sun. How would you even get rid of it, do you throw a black hole at it and then put warning signs up?"
"The sun, I already know why the plane wouldn't be destroyed. Because it is the tacky grounding point."
"It's... Sort of comforting, to know there is an afterlife where I would actually be able to do stuff."
"Sort of. Zane and dad would be going to Limbo, and you're pretty insistent that I would probably end up in Heaven. So I'd be alone."
"You could convince them to each summon something once, I think that would probably do it."
Adana nods. She snuggles Cam. "I mean, none of us are planning to die soon, so you've got time."
"I think so. My parents haven't encountered anyone in Limbo who remembers doing even that much."
Adana smiles a little. "Okay, that makes it a bit better. I mean - two out of three chance that they will be in either Heaven or Hell, so - one of us would have someone there, probably."
"Well. Then they'd... Have each other, if they're both fairies? And not be stuck in Limbo?"
Cam nods. "It's not an ideal setup, but Limbo's kind of - disappointing. There aren't enough concordances."
