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.

The Dream Destroyer is so named because of her hatred of happiness. Whenever she sees a happy couple cooing over their egg, she will make note of it. Once night falls, The Dream Destroyer will creep out from her secluded cave and sneak to the new family's cave. She will then bite the egg and leave the turned, or possibly even dead egg for the parents to find. In this way she destroys the dreams of parents who wish for a happy child, unburdened by bloodlust.
