He feels an open summons and lets it grab him -
"I'm sorry I didn't warn you," Emma apologizes quietly. "It didn't occur to me. It's mostly like- you sometimes meet people who are good at reading facial expressions? At least for me. Selevy just has a really good psychiatric empathy program, so... empaths."
"At home the kinds of magic that exist are limited absolutely to trivial parlor tricks, personal indestructibility, moving stuff, changing stuff, and making stuff, with the last three one to a customer and only for daeva. Not a thing with mental effects."
"Oh, and summoning daeva, that's also magic, but not a parlor trick. Parlor tricks are tiny laborious telekinesis, slowly and unevenly changing the color of a thing, stuff like that. The only common use is for disabled people."
"All of you, apparently, fairies are the telekinesis types where I'm from." He sets about making an 'Okawa A3'.
Well. It's like she got her master's degree in telekinetic algorithms, or something.
A small bracelet-like device appears in Cam's hands. It has two smaller straps that go tightly around his wrist, and a larger band on top of them that looks electronic with a small display. The display is currently dead.
"That's not promising," Professor Reed says, eyeing the display, "but you might as well try it on."
"Sure. I nominate you to represent the school." He hands it to her. "Other kind might still work?"
"...Okay, so if I wanted to conventionally recharge this battery, would I use a cord of some kind that would connect on the other end to a two- or three-prong outlet in a wall, provided I was in the United States at the time?"
"I'm asking so I know how to line up power conversion for replacing the battery with a smaller batter, because this thing is clunky." He hands over the second object - "another donation for you" - and makes a new thing, which is considerably smaller. "There. Okay. Shall we?"
The dean's office is split into two; the front half is clearly a tiny waiting room of sorts, complete with posted office ours and a variety of chairs that look maybe about half-comfortable. A voice comes floating through the open door.
"Tamara! Took you long enough. Come in, come in. I hear we're breaking laws of physics today. And meeting mythical species? I'm losing track. Far more interesting than paperwork, anyway!"
Everything is more interesting than paperwork.
