"The problem is that the intersection of 'people whose reasonableness I trust' and 'people who I can think the right way about' is pretty small."

"How do you have to think?"

"I would like to assume total control of this person, their thoughts and desires and actions, and use that to harm them, and keep them that way -"

Twitch.

"I have never and will never use it without consent."

"I believe you but that's kinda..."

"I know."

"I could probably cast it but I don't know if I could cast it on people I liked."

"I don't have that problem, I can't get myself into the mental state unless it'd be okay if they didn't like me afterwards."

"Huh."

"I have a lot of control over how I feel towards people. But it's hard to put myself in certain mindsets if I feel like the justified reaction would be not trusting me and I couldn't actually live with that."

(Geez, what happened to the sad demon.)

"Anyway, Miranda, want to read about 2179 and then help me figure out how to fix up the world? Minor and my father are working on the technical aspect."

"I have actually been trying to get Bar to find a world with our magic system where it is later."

"...oooooooooh."

"Bar is having some trouble with it."

There is no way for me to directly verify common magic systems, only published works, which may match for a considerable time before diverging due to later discoveries.

"So, like, there are worlds that have On the Fundamental Principles of Transfiguration word-for-word the same as ours but then it turns out their magic system is different, later?"

Yes.

"Bizarre. Okay. 

...trying to think of a safe way to let everyone summon..."

"Do they have to know they're doing it?"

"No. But they do have to voluntarily dismiss the daeva, or die. Since the idea is death insurance we could just have a lot of daeva long-term in your world but that sounds complicated to say the least."

"We should verify that people who die in our world do become daeva if they summon before we expend too many resources assuming that's the case."

Nod.
