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.

Jason is a member of The Fortress.

He is a pretty dubious dragon. On one hand he is proud to be a Vampire. He likes to be out during the night and he thinks the "living" dragons are worthless. On the other hand he is truly afraid of Louise and her longing for eggs. Since she is a vampire too he admires her. But he would like her better if she wouldn't feel sorry for everything she did. So he started to make her viciousness look funny by making sarcastic jokes.
