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.

Bloodsucker is very mature, but always seems to be picking fights with his cave leader, Guardian of the Ice. Nobody knows why he does this, but he always seems to enjoy it. Most dragons think that he does it for the pleasure of spilling blood, but there's no proof. Other dragons think that he does it to defeat Guardian of the Ice and become cave leader, but most dragons know that Bloodsucker will never become cave leader, especially with the fact that he's always trying to kill the eggs.
