The shrens are very solicitous of her and will let her look at them all she wants.

Great. How the hell are they not dead.

Precariously.

How do their wings tie into it?

Helpfully, if your goal is for the shren to be alive!

She would like mechanism, please, not efficacy.

Like this.

Yup.

The Corenta house doesn't have one...

The Corenta house is in Corenta, which means it's in something-approaching-reasonable flying distance of the wizards she knows.

Corenta's a long skinny country, but yes, her wizards are over there.

Great. She needs to be teleported to the Esmaarlan shren house again.

Sure. Pop.

"Jensal! Jensal!"

Jensal emerges from her office, a paperweight spinning in place over her hand. "Yes?"

"Sympathy's good at information so I was looking very intently at some shrens and if we had handled the flying thing just a little differently someone could have died."

"It was--the way I was doing it, I was, technically, sort of--reinforcing their wings, holding them up, but externally? Shrens are sort of constantly on the verge of dying, and they're sucking strength out of their wings, and if there's more strength they suck harder and if there stops being as much to suck on..." she shudders.

"...I see. You should tell Ehail, that would be relevant to her research."

"Ironically I didn't start staring at shrens in earnest until we had just finished a conversation and she left."

"I have a communication crystal for her."

"A what?"
