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.

Zirthes is a strange one in the fact that he viciously defends the cave, and surrounding area, from intruders. He occasionally has problems controlling his blood thirst, but whenever that happens he goes to Zierra.

  He and Knight often compete with each other to see who is the better defender, often resulting in loud growling and roaring matches in the dead of night, often resulting in a scolding from one of the other dragons.
