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.

One Wrong Move, often simply called One, got her name from her obsession with watching the entrance of her master's dragons' cave system from a ledge in the tunnel. She began doing this from the moment she hatched, and has since kept her ominous red eyes on the rocky opening, pinning any visitors down with a malevolent gaze as she sits unmoving. So far there have been no incidents, although her stare always suggests that one wrong move is all it will take to find out what she's really like.
