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.

Aerovyrn is a dragon considered by many scholars to be a topic of extreme interest, as his role in his ecosystem among other dragons suggests that dragons have something of a morality system. Such a questioned is raised around him because many times have people observed dragons bringing their sick, or extra eggs to him, with sad eyes but begging hearts. Many think these eggs are brought to Aerovyrn because these dragon parents want their eggs to still have a chance to live on, even as a member of the undead, as they would be unable to take care of the egg otherwise. Any egg that is brought to Aerovyrn and survives the transformation from his bite is taken in by him and raised until they are old enough to care for themselves.
