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.

Leese's lair lies in a dark cave, resting on the steeper side of a mountain that overlooks a small human settlement. Every full moon, the villagers sacrifice her a lamb as a peace offering, and she does them no harm, nor does she pay them any more attention than required until the time to accept another sacrifice has come. She is not evil, that is simply a prejudice that has come to be associated with her species. However, since it is widely believed by both human and dragon alike, she does not make herself known when an unexpected harvest dragon decides to settle dangerously close to her territory. Leese simply observes, and in time grows to admire her kinsmen. Perhaps eventually she will make herself known, but for now, she remains hidden in the shadows of night, a silent observer bearing witness to what she has come to know as her forest.
