WiF vampires are a lot like earth humans. Same lifespan, same general anatomy, same set of races. The only difference is that they can use magic, but can't produce the magicka on their own (it's like a video game where you need MP to cast spells, y'know.) So they're rumored to drink Satyr blood to get the magicka from it, though in modern times they've developed less messy ways to get it out of Satyrs. Still, the term "vampire" has stuck, even though properly they're called "common humans" or just "humans", though the common is added on to differentiate from the other subspecies of human - Kirsaian.
So Xu-xu is a Kirsaian/human mix, really, with a mixed ability set... She has a dragon form like a Kirsaian, but it's small, and she has magic resistances like a vampire, but can't actually use magic herself. I can go into loads more detail, but I won't unless you want me to. XD
And you know, I wouldn't be too surprised if she was holding a baby polar bear wrapped up in a warm little blanket or something... But maybe the police are after her because she's keeping an animal that's endangered. XD
to see a chibi of Aisling! Her name wasn't mentioned at all in the comic yet, but you'll know her when you see her (if you've read it, of course)!
