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.

Blood Fang is a vampire dragon. Unlike others of his kind, he doesn't like to drink the blood of other dragons. So he drinks the blood of animals. He was raised by Sunny Rose is the hope the Blood Fang would bite... everyone. Blood Fang disagreed. Blood Fang, as a hatchling, was always being yelled at for being too close to the hatchlings. He couldn't help but be jealous at the hatchlings loving parents. He was drawn to a hatchling named Holly Tail and is now 'mates' with her. Even though he is scared about hurting her.
