"I just make it a point to go once a week, for this form, since, why not, public lightcraft in Esmaar, and that way I don't totally ignore a broken foot or whatever," shrugs Finnah.

"And witches are...?" says Linya.

"Oh," Aurin puts in, "lights don't work on themselves or each other, so if they get sick or hurt they go to witches, who make potions that do various things, depends on the witch, painkillers or shampoo or, since Mial is planning to be obnoxious with his natural form these days, I suppose scale polish - whatever."

"Okay, well, 'medical stuff' is more similar to witchcraft than to lightcraft, where we're from," says Linya, "and it involves perhaps most centrally knowing what's wrong. If you've been - poisoned and with what, or if you broke or strained something and exactly where, or if your heart's beating too fast, or what your body temperature's doing - any of that counts as medical information. The scanner is really less useful for seeing what dragonishes have in the way of genes than the sequencer is - I'm not sure if I'll need separate blood samples per form to look into that or what."

"The blood should be the same. I mean, at least according to vampires," Finnah says.

"...Vampires," says Linya.

"Oh, I guess you don't have those either. Do you have anything?" wonders Aurin.
