There is a bar. In the bar is a young woman sitting at the counter, sipping something orange, reading from a pile of paper napkins.
"I haven't had that many assassination attempts! But I am clumsy. And get almost a normal number of diseases."
"Accidents are harder to solve than disease, unfortunately."
"I guess that makes sense."
"It should still be possible, but it'll take more time to figure out."
"I'd really like that. If you feel like making a near stranger immortal."
"I don't give people powers I can't counter, and it'll be a valuable experiment, besides."
"Wouldn't you have to go home with me to counter it or have any information about whether you'd want to?"
"I can create multiple bodies for my mind to inhabit, so will probably dedicate one to wandering through other people's doors anyways. I'm unsure if I'll be able to remained synced even across universes, but I'm willing to have a fork stranded as part of the experiment."
"What would you... do, in my world?"
"Explore and ask questions, mostly, and then see if it's easier for one of my bodies to return to my universe than it is for me to leave."
"What kinds of questions?"
"Similar to what I was asking you, somewhat, as well as culture, history, social, political... I like learning things."
"That makes sense. There's a translation effect here, though, I assume you don't really speak Welchin."
"Learning the language will be interesting as well."
"Are you faster at that than a human?"
"I believe so, though I haven't often been challenged - I simply keep up with languages in the mortal world as they develop. My memory's perfect, though."
"That'd help a lot."
"I suspect it would."
"Probably if I'm going to wander off to try working on the spell, we should set how often we try to contact each other? In case one of us is faster than the other. I'm also going to want some ex-mortals from my Realm..."
"Every... week? I'm planning to be here a while."
"How many days is that in your culture?"
"Every ten days works for me, then."
"I suppose days might also not be the same." She makes some mental transaction with Bar and comes up with a room key. "I'm in 265, apparently."
"Right. I'll find out my number, then."
She goes up to Bar.
"I'd like a suite suitable for experimenting with magic in, and for multiple mortals to be able to inhabit, please," she says.
49021. Key. The charge is by subjective day for whoever experiences having access to the room longest.
