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.

Kyuuketsuki is a very scary and creepy dragon. He sleeps silently at the darkest part of the cave during the day, and crawls out of the cave only at night to do things no one knows about, or even cares about. No one really knows about Kyuuketsuki because they never go near him because he looks so hostile. All the adult dragons tend to keep away from him, and all the hatchlings follows the adults' example. They also try to keep the eggs away from him, but once every month, Kyuuketsuki somehow manages to bite one of them.
