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.

Runner Horse Of The Dragon is so named by the fast running take offs he has. He is always being teased because of looking like a female breed and is always being threatened to be eaten if he didn't improve himself. So he lost all the bad calories he had and only ate healthy things. He looked more muscular and all the females loved him. He said "Right now I'm not looking for a mate right now." When someone left the egg outside the cave, thinking this was the one, the dragons and their owner agreed to take care of the egg. Even if he has important needs, we would still do our best. As an adult now, he does the Proven Test to see is the territory sees if he can attack prey off and make him the attacker. He started a club called "The Lucky Hits" to teach baby dragons and adults how to attack, even if they were differ breeds from him. He has fallen in love with the female, Swamp Of Fire. He feels as part of the group and now isn't teased any more because of his mate.
