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.

Boo Radley von Lesserd is a reclusive vampire dragon who would just rather be left alone.  He mostly spends his time in his section of his owner's cave system, carving little dolls out of wood and hiding them in the other sections.  Boo never talks to any of the other dragons, and this mysterious behavior has caused many untrue rumors about him to surface.  His "legendary" status in his owner's cave has made him an object of curiosity to the hatchlings, and they are constantly trying to make him come out of his cave.
