Vasteria

Character I designed a long time ago, based on an actual plush I have. They're a bat plush whose wings have a slowly animated galaxy pattern with glow in the dark stars, and they can link up the stars to make constellations however they like.

Their name is derived from "Asterism", which is a group of stars in the sky, with the "V" coming from "vector graphics" - because early forms of it also involved forming pictures out of straight lines. And "Aster" is a flower that's purple like this bat!
