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.
"Also, I told my dad and Zane that they should summon a fairy. I'll explain why in person, I don't like telling sensitive information over the comm, other people could hear it and I am keeping this a secret until it seems appropriate to stop."
"Good. I should be valued for my intellect and not just my prettiness and my ability to make arbitrary material objects."
Adana laughs a little, then touches his cheek. "You weren't worried about me wanting to date you for your ability to make arbitrary material objects, were you?"
"No. That does not mean I will not cheerfully listen to a complete list of why you do want to date me, though."
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."
He is indeed hugging her. She is hugging him back! She considers him very huggable, too.
"All your fault. Probably I was terrible before I met you. Collecting souls and whatnot."
"Mhm." She sounds very unconvinced. "Well, in that case, how do you know that I wasn't terrible before meeting you, too? You are also quite huggable."
"Ooh, maybe you originally wanted me to suck the entire moon into a black hole for revenge purposes, but then I won you over and you decided to have me save people instead."
Adana giggles some more. She keeps being embarrassingly giggly around him. "The space station was originally designed to be the modern equivalent of the Death Star. I was going to be empress of the solar system, it would have been grand!"
"No, no, it's okay. I have changed my ways, that's all behind me, now. Your hugs have changed me!"
She laughs. "What would I even do with it, I'm not going after empresshood anymore. Honestly I'm not even going for 'major historical figure,' if human society runs better overall once I am done with it I will be pleased."
"If I had not been murdered I probably would have angled for eventual rulership of some manner of political unit. I could have got in very early on space colonization."
"Awwww," murmurs Adana, nuzzling her demon boyfriend. "I am having more reasons to hate that you were murdered, I'm extremely sorry."
Kiss. "It's okay. It worked out surprisingly well compared to what results I would have expected from murder."
Kiss. "Well, yes, but still. I'm sorry you got thrown into retirement so soon, knowing you... You would have gotten a lot of good in the world done. Also, horrific early death, also bad."
"I would have done so much stuff. I used to let demons talk, I would've found a decent-enough one eventually and gotten so much stuff made."
