After Cam's magic but still basically human boyfriend has fallen asleep and Cam finds he is not tired enough to do the same, Cam goes downstairs.
"I'm unclear on what the Flat Arda ones do but the space ones were supposed to get backups without Mandos's intervention."
"I suppose the Flat ones could do the same thing, they never come into play as anything but shinies."
"Soul-collectors? Anyway, the Valar don't actually do anything punitive after the war in either of these accounts of it - including against Melkor's lieutenants, for that matter -"
Flop. "So what, aside from the usual constraining factor of evil intent, do you need to cast the Imperius on somebody, and do you think you can convince Theodore's alt's grieving pet Maia to be a test case?"
"There's a range limit, it works on all the sapients in my world and if it doesn't work on Maiar I'd expect it to be either because they are magically resilient to mind-affecting magic in some way - but there's no mention of that, they can make oaths, so that doesn't seem likely - or because they have too much mind or too strangely-structured a mind for me to do anything with it. I don't know if they need to currently have an embodied form. I could cast it on someone invisible if I knew exactly where they were. A bunch of things - how much attention I'm spending on it, how directly I have to be controlling things, how easy it is to throw off - seem to improve with practice."
"I am not overwhelmingly optimistic. Could maybe find a Maia test subject in the flat Arda, assuming they're the same sort of thing."
"Well, he's not going to agree, but I don't object to attacking him, but he might warn Melkor if you can't hold him."
"Don't like bringing him here, even with the oath as thorough as it is, but the chip Elves think they can get portals eventually."
