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.

Homer has been described as a friendly dragon. He enjoys the company of both humans and dragons. As a result, he runs a bakery out of his coven's cave system. Although he doesn't need to eat, he enjoys eating his baked goods almost as much as he enjoys making them. His favorite treat is a dessert called donuts, the recipe for which he got from a human adventurer whom he helped in the past.
