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.

Darkhorse Yearling is a somewhat romantic dragon, though he is very shy and can be afraid to let others get to know him. Ever since he was just a hatchling, Darkhorse has had a crush on a certain Rosette Featherling, but cannot bring himself to tell her so, because she loves Ronnie Sweetling. Darkhorse and Rosette have been very close for a long time now, and all the dragons in their clan are waiting with their fingers crossed for Rosette to finally realize that Ronnie doesn't love her, but Darkhorse does, but even Darkhorse himself knows that it may be a while before that happens, so for now, he is content to wait for her, and be there to pick up the pieces when she falls.
