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.

Easily one of the most aggressive dragons in Kurei's nursery, he only allows other vampire dragons anywhere near him. He was abandoned when he was little, the other dragons near him being so disgusted with a 'dead' dragon walking around them at night that they nearly killed him. At that point, Monstrum, the vampire dragon who found him and brought him to Kurei, was the only other vampire dragon that he had seen. Of course, he reacted badly to meeting Kurei, Kurei having the bite scars to prove the encounter, but he soon won over the scared hatchling. Despite that attack, Kurei decided that vampire dragons were his favorite to raise, due to helping this dragon reach adulthood.
