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.

Umurake is much younger than most of the Undead Pack and has consequently always felt like a bit of an underdog. Not only must he submit to Makenna, the Pack's leader, and Ukuren, her trusty second in command, but the impetuous Maraeva uses him as a punching bag when she gets particularly angry. Makenna does not approve of this, since she knows the Undead must remain united or be driven out entirely, but she knows that Maraeva will either attack Umurake or the living. At least when it's Umurake, she can do damage control. So the young male sucks it up without complaining, knowing that however unenviable his position may be, he is a necessary part of the group. His greatest feature is that he would never take out his frustration on those weaker than him, such as the frozen Undead hatchlings.
