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.

Ripped from his parents while still an egg, attacked and later abandoned by a wandering Vampire, Grave Sinner found his way to the crypt-weyr of Hellish Katrina Undead.  Here, he learned the ways of this rude family, along with their vicious techniques for the pursuit and torture of their prey.  Called "Sin" by those closest to him, he lives his cold life without remorse, without mercy, and without any vestige of his soul.
