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.

Free Fangs is Brave Blood's apprentice. He has not learned the average disposition of vampire dragons because Brave Blood is a pacifist. Yet he does feel this odd sense of hunger when he sees the eggs his owner adopts. At times he wonders what kind of dragon he was meant to be. He refrains most of the time, but occasionally bites an egg for other dragon tamers' sakes.
