"I am pretty sure I could tell if Cam were lying."

Nod.

"I'm a lot more afraid of what someone could do controlling a demon."

"Especially if it requires specific - practice or something to use the magic right -"

"Yeah. Ideally all the daeva doing anything in our Earth would have a lot of practice at throwing off the Imperius but I can't pressure people to do that and you can't really get good enough not to even be disoriented..."

Nod.

"Can't just let everyone die either, though."

"If we get the daeva-wizard interactions wrong enough everybody dies."

"And if we do nothing everybody also dies."

"I know, but let's not commit instantly full speed to the first mass distribution idea you had. For one thing if nothing else it wouldn't work abroad like that."

"Yeah. I don't know enough about their Ministries to know what will slide under the radar there."

"We can't plan for indefinite secrecy. Even a very well-crafted plan to tell about a billion Muggles things will get back to wizards soon."

"Agreed. We should assume wizards are going to find out."

"I'm not sure magic couldn't get to Mars if someone really wanted to go, too."

"The point is that it'd be trivial for a demon to notice someone coming."

"And do what about it, though?"

"Cam has not been making a production of it but I am pretty sure he has a lot of ways to nonlethally disable us if he wants to. And then send them back, I guess."

"Magically unblockable ways?"

"I mean, if someone is sufficiently determined to block nonlethal ways of disabling them then I am very sure there are some unblockable lethal ones."

"Suppose."

"We can ask Cam and maybe also my father but I don't expect 'shut down daeva from interacting with any of the space within a hundred yards of me' is a thing magic can do and that's pretty much what you'd need."

"Anyway, given that we can't plan for secrecy to last very long or even for any particular length of time I'm not sure it makes sense to build plans on having it even temporarily once we get to the point of mass distribution."

"I think the existing institution everyone participates in with rituals for small children is the best way to do distribution without lots of illiterate people trying it at home and making costly mistakes."

"Likely, but that's separate from the secrecy part."

"Yeah, agreed. And it'd just be until we get universal literacy, I don't know how long to expect that to take."
