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.

It was a living nightmare when Mionn's parents discovered her egg had been bitten. A cave filled with Guardians but still a Vampire had injected its venom into their offspring. As Mionn hatched cold and undead, her own father attempted to kill her, but her mother grabbed the hatchling and hid her in a tree stump. As night fell, Mionn climbed out and was greeted by a dragon with cold red eyes, waiting for her. He was so unlike her family, yet Mionn instinctively felt he was more like her than her own parents.

Mollachd raised her as both a father and a brother, but Mionn would not fully be accepted by the other Vampires unless she had turned an egg. As she matured, Mollachd and Mionn set out to seek her first victim. As they flew her surroundings became more and more familiar to her, until Mollachd landed at the entrance to her parents' cave. Overcome with her bloodlust, Mionn did not hesitate but dived into the cave and bit the first egg she found. Mionn had passed on her curse.
