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.

When many figure out what kind of egg it is they usually want to drop it into the middle of the deepest lake they could find. But, all things deserve to live—and actually she isn't all that bad. She only eats dragons' blood, so doesn't mind humans, or at least she doesn't attack them. As a poisoned embryo she is underdeveloped and only half the size of most dragons. Unlike vampires in stories, she is more like a vampire bat and does not kill her victim, just bleeds them and leaves them breathing. The venom, used to turn an embryo into one of her own kind, has no effect on an adult; it only makes the blood flow and anesthetizes the area so the victim doesn't wake while she is feeding.
