"Mental notes, rather, supposedly they have really good memories. And there's probably a spell that lets them write, which I have not bothered to look into, not having one."

"Oh, huh."

Yawn. "Eugh, who knew sitting still could be so exhausting. I should probably talk to Kanimir before I turn in tonight though, technically I don't think it's been said if my offer of hospitality extends past last night. And ask if he has books on magic I could borrow now that I can read English. And for less endorsed reasons."

"Less endorsed reasons?"

"Uhm. He's very pretty. You're all very pretty, probably has to do with having heard of hygiene and nutrition ever, but he is unreasonably so. I imagine it's a magic vampire thing."

"Oh. No idea. I've met his sister, though, and she's pretty too. And also a vampire. Not magic, but if it's magic he could've done for her."

"Apparently politicians do better if they're attractive, so if there's easy magic to become prettier it would be very useful in taking over my world. Which sounds like a very convenient reason to ask him why he's so pretty and so maybe shouldn't really be trusted."

"Being pretty is an advantage but not a huge one on the scale of taking over the world, I bet."

"It can help with first steps, I imagine. Getting the first country or two and leveraging those into the world. And my world is less connected than yours, it is plausible that I could semi-legitimately wind up in charge of many countries before anyone caught on and I had to switch to conquest and mind control."

"...I advise going heavy on the conquest and light on the mind control."

"Are you concerned I will have trouble maintaining it or do you think it is better for ten thousand to die in a war than for twenty to lose their wills?"

"...I think it's more a matter of misunderstanding what you meant when you said mind control."

"Oh, I wouldn't try to do an entire populace. That would be horrible. Also a logistical nightmare. But mostly horrible."

"I don't know enough about magic to have any idea what the logistics would be like but the horrible part was apparent."

"I would have to do each person more-or-less individually and refresh it personally every couple of weeks. And I actually just can't, I wouldn't have the energy for all of them. Maybe it's doable over a wide area with some big elaborate ritual, but that wouldn't be total mind control, probably just inspiring loyalty and community-mindedness and cooperation."

"Seems like it would have knock-on effects."

"It might. And patching those with more mind control would probably not be a great plan. And eventually I'd want to transition to a mind-control-free society, so it would need to be gracefully removable. If I ever did it I'd do it much more carefully than 'Oh I think these traits would be good in a population.' "

"Yeah, definitely."

"Speaking of mind control, I really should talk to Kanimir about the duration of my stay if nothing else. Do you know if he's up yet or the best way to talk to him without interrupting anything important?"

"He usually gets up at around sunset, he's okay to bother if he's just sitting in the library reading and if he's not he probably isn't."

"OK, thanks, I'll check if he's there." Library?

Yep.

"Hi. I realize I asked for one night's hospitality and then after that night I spent all day reading Wikipedia and now it's night again. And I should probably check whether or not you are actually willing to host an interplanar vagrant medium-long term and if not figure out other accommodations. I'd also like to know if you've heard back from the angel?"

"Ah--yes, you have a fascinating magic system and I have abundant resources with which to house people with human needs. You're quite welcome to stay arbitrarily long. The angel did reply, she's interested in coming and meeting you."

"Delightful. I would be happy to continue trading magical knowledge with you, if you have the means to acquire lots of inks - I think of them as mostly pretty expensive but it's possible they are less so now - I can try diagramming some spells for you and we can see if you pick them up. And you mentioned there were books I could learn your magic from?"
