Cam is dipping a grilled cheese sandwich into a bowl of tomato soup when he feels the summons. He goes ahead and grabs it. Doesn't even drop the sandwich.
"So you said you can make stuff, right? So you're some kind of super-craftsman or matter generator or what?"
"Matter generator. I can't do antimatter, there's pretty sharp limits to how much information processing and handling I can embed in an instance of making, and I have a range limit measured in astronomical units but can most precisely place things given precise maps or line of sight. Also where I'm from it's the year 2159 and I have thorough educations in medicine and engineering and hobbyist-level computer science. I'm a useful person to have around."
"He is our science person! He invented a bevy of helpful machines and has done some worthwhile medical stuff although after the incident where he turned himself blue and furry someone else always checks his notes on the latter."
"It sounds like I should talk to Dr. McCoy. If he prefers not to be blue and furry for any reason, possibly also an angel should talk to Dr. McCoy, but only after we know more about how this unexpected universe interacts with daeva summoning."
pause.
"He wants assurance you're not going to try to charge him his soul in exchange for fantastic science things."
"Okay, the lab's this way," she says, opening the door of the room and gesturing for him to follow her.
Cam is given some odd looks by the people they pass in the hall, who are mostly teenagers or younger, but this seems to have less to do with his wings and tail and more to do with his lack of shirt. The person with wings he sees, who briefly interrupts their progress to discuss some kind of social thing with his guide, is wearing a shirt, tailored to fit around the wings.
Well, if anyone asks Cam to put a shirt on, he can do that. He doesn't feel inclined to put one on just because.
"Cool. I have what amounts to several technical qualifications, but they're from the future - albeit not a future with the local kind of mutants - and backed up with magic. Are you a good place to dump lots of advanced medical knowledge and feel confident it will be distributed generously?"
"I mean," says Cam, "I can prove the magic part. And the technology part. If you know who else I should ideally be talking to I can go talk to them after making them future gadgets from thin air."
"Yeah, fair point. Malaria I can fix myself in a day trip, everything else ought to have a non-daeva-based pipeline from synthesis to prescription. Lemme start you with some books." Cam makes him a stack of books.
"Oh, I mean it will still exist after the day trip. The active work will just be done then. An overwhelming population of sterile male mosquitoes will do the rest."
