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.

Leathal Fang is quite gentle compared with the reputation of other vampire dragons. He is quiet and caring and always hesitates when asked to bite an egg, knowing that his poisonous teeth could kill the poor creature inside. Despite his subdued behavior, many members of his cave try to avoid him, whether because they don't want to suffer through the stench this male carries around him or if they truly believe he acts like a typical vampire.
