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.

Taken in by Monstrum, like many of her new clan, she was brought in to her handler, Kurei, as a helpless, damaged egg. When Atrox hatched, she was... different. She didn't enjoy the same things as her fellow clan mates and would get into fights with wild hatchlings, often resulting in both parties getting seriously hurt. After she grew up, she left the sanctuary, in order to learn more about herself, about her family and about the vampire who turned and left her behind. It was several years later that she finally came back. When Kurei tried to talk to her about it, she only said, "Blood corrupts..." She hasn't spoken a word since.
