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.

Mirikk was the first male vampire to join the Kin Clan and, since Avea had been searching for a male, it seemed like a miracle; hence his name "Mirikk" which sounds like a shortening of "Miracle". However, despite how special his coming was, he is a very violent dragon and to keep him contained Avea was forced to seclude him to a cut-off section of the cave where he can't hurt anyone. Some times he can be heard screeching and scratching at the cave walls, trying to get out and hunt.
