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.

True to her name, Stable is the kind of dragon that would rather sit back and enjoy the scenery. Unlike her brood of overactive, energetic, possibly sadistic siblings, Stable is chill and calm at all times. The most activity she'll do in a week is take a light jog around her home sanctuary, and perhaps do some hunting as well if she's hungry enough. Stable is a very friendly Horse Dragon. She'll accept partnership from just about any breed, even more dangerous, ill-tempered ones. She's rather equipped for it having so many Hellfire and Hellhorse siblings. Speaking of which, her more radical siblings actually look up to her quite a bit, particularly as a maternal figure. Their actual mother, Equestria, has proven not to be the most devoted or accepting parent. This explains why so many of the Firestorms prefer Stable's sweet, calming demeanor over Equestria's more controlling impulses.
