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.

A lurker of the night, Halott was transformed into the being he is now on Hallow's eve. He carries the clan title of Ver, the name given to all Vampires within the Kes clan. He is a proud, temperamental and neurotic dragon. He rarely stays within the cave  for long, and tends to spend time with his vampire companion Maris. Halott was at first lonely within the clan, the only beings who would bear his company would be the three zombies, Ike, Repugnace and Disgust. Though, after two torturous months, he had finally successfully sired a vampire egg. That was when Kalon Kes joined the Ver title.
