"I can't claim credit for the idea."

"Oh?"

"It was implemented on the Earth I'm more previously familiar with. Nobody consulted me on the project."

"Ah. Well, it's good of you to replicate it in our universe, as it seems to be. Was the rest just these books, or was there anything else?"

"Oh, there's lots, but it seems more efficient to start you on the books while I'm off making mosquitoes. Will you be able to read more than that in the next twenty-four hours?"

"Yes."

Cam goes hmmm and makes a futuristic little computer and looks through its display as it shuffles around. "Any chance you read Chinese? I can probably find a translation of these ones but I don't already know one..."

"I do, actually."

"Cool, so I can throw in these - I'm reasonably sure you don't know Lagalann, that's a demon language - Latin?" More books appear.

"Yes, actually. To the Latin, you're quite correct that I don't speak the demon language."

Some Latin books join the pile. "Okay, so, these are my demon medicine books, most of them from 2039 to start you off with relatively more context, and this stack is an update on the series from more recently. Because they are aimed at demons they say things like 'apply an even distribution of a total of 2ccs of metracorazone to the arterial blood' or 'if you are permitted to speak and working with other daeva, ask attending medical fairy to suppress blood flow to the tumor' as opposed to things like 'inject this stuff' or anything else demons easily work around. However, they do have chemical formulae even though we don't strictly need them so that we can make judgment calls about unexpected possible drug interactions, and conversion tables and sidebars for talking to human doctors, so if you're six-PhDs-and-multiple-languages smart you should be able to work backwards and get a lot out of them. Do note any questions you have for me and I'll be able to clarify out of my notes when I come back. Sound good?"

He is already paging through the books. "Sounds great."

"Awesome. It is a little early for you guys to have a functioning Internet, so do you happen to know off the top of your head what regions of Earth are currently affected by the malarial mosquito?"

He reluctantly abandons the shiny new books to look through some periodicals, and names some places.

"Great. And can any of you point me to a good place to take off in a sedan-sized stealthy spaceship?"

"Somewhere on the lawn that doesn't have anyone there should be fine."

By this time, Dr. McCoy has finished the books Cam gave him, and someone has informed the Professor of all this business.

Well, Cam doesn't know that there even is a Professor except insofar as the man with six PhDs may qualify, so he goes looking for Dr. McCoy to fill in any gaps the stack of books left.

He appears to be talking to a man in a wheelchair.

Cam can wait.

They break off a few moments after Cam gets there, and the other man turns to face him. "Hello," he says. "You must be...the demon. Whose name it would appear my daughter and her friend neglected to ask for. I'm Professor Charles Xavier, and I run this school."

"My name's Cam. Hi again, Dr. McCoy, did you like the books?"

Dr. McCoy begins expounding enthusiastically on the contents of the books.

On which Cam will happily converse.
