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.

Tsuki-Tenba is currently the only dragon in her owner's care that has a Japanese name. Her name means Moon-Pegasus because she is mostly nocturnal, her dark violet coloring helping her blend in with the twilight shadows as she stalks her prey at nightime. Nicknamed Tsuki, she is usually neutral but gets rather grumpy if she is awakened from a daytime nap. Tsuki is named in Japanese because she rejected all the English names and her owner couldn't think of anything else.
