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.

Vampyro, one of the few Vampire dragons in Obdurate's dragon pack, spends most of her time alone, gathering herbs. Although many Vampire dragons are said to kill hatchlings, Vampyro loves hatchlings and would love nothing more than to take care of them or have a few of her own. Sadly, due to the fact Vampire dragons are undead, Vampyro cannot bear children of her own. She has taken on Bloodteeth, another Vampire Dragon, as her adopted child.
