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.

Creonus is one of the highest ranking members of a pureblood vampire clan; One of the members of the council which is made up of 5 dragons. He is in charge of military and the warrior vampires in the clan. He leads them all into battle and he is a very successful military leader. Creonus is usually quiet and spends his free time thinking. He also scouts for new warriors within the clan. As of late, he seems to have soft spot for Yukina. Creonus is indifferent about non-pureblood or as the clan calls them, "tainted" vampires but he won't hesitate to attack if one gets in his way.
