Horse Dragons have equine-shaped bodies and hooves instead of claws, which allow them to be fast runners. They specialize in running takeoffs, which are quicker than taking off from a stand-still. Horse dragons are able to stalk their prey from the ground then quickly execute an aerial attack for the kill.

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.

Billie, as he is called by all, is a dragon picked on by most other dragons because of his name. The other horse dragons in his herd are really the only creatures who do not laugh at him. They too feel his pain. When Billie asked his herd's human caretaker the reason behind their names, she replied that their names were a tribute. She went on to explain that they were a tribute to a great singer and that each of their names were in fact a line from one of his songs. Now Billie respects his name and is bent on making the other dragons respect his name and that of the dragons in his herd as well.
