Vampire Dragons are members of the undead. They sustain themselves by drinking the blood of others. It is said that they are only “alive” at night, and seem dead or asleep during the day, as they cannot endure sunlight for long periods of time. Vampire Dragons can only reproduce by changing the eggs of other dragons, puncturing the shell with their fangs and injecting venom that kills the baby inside.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Bite Bite You All, or Biter, as she's been nicknamed, wants to destroy the ideas of the living by biting all inbred dragon eggs she finds. She hates the Blaublut family since they don't agree with her, but loves the Serthes' dragons for their morality. While during the day she simply hordes all inbred eggs she found, since she can't go out and find some more, but during the night she stalks caves, looking for dragon eggs that have been lost and she feels deserve to be bitten.

Soon into her project though, she hit a snag; she emptied her store of venom with one bite, and had to wait too long to bite the next eggs. So she spoke with a friendly dragon named Death Dodger, who had no fear of vampires or other creatures, and discussed the matter with him. He granted her a gift, promising to freeze one inbred hatchling every two weeks, so that their blood would never be passed on to other innocent dragon eggs.
