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.

Izumi never knew her biological parents, but was raised by a nice couple in the valley. She is a very energetic, brave, and social dragon (very different from her mate Hikaru). Her and Hikaru grew up together, and were best friends from the start. Once she mated with Hikaru she became a part of an even larger family, and she loves it. She loves to socialize with all the females in her family, and even jokes around with some of the guys. She is so proud of her mate, he protected her from an evil dragon that tried to steal her away from the valley. That's how he ended up asking her to be his mate. She said yes, and has never even come close to regretting it. She loves him with all her heart and more, and he feels the same for her.
