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.

Snap Dragon has almost no emotion. His 'mate' is Dew Drop of Blood, the psycho vampire who obsessively wants an egg. The only reason Snap Dragon is with Dew Drop is because he wouldn't mind having a child to do his bidding. Unlike Dew Drop, who tries every day to get an egg, Snap Dragon is plotting carefully to get an egg. Although Snap Dragon is very unemotional, he is very curious. He often leaves the cave to try and find something out he has wondered about.
