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.

Era's hide shines when she is near a pond, which is very often, since she enjoys her own reflection. She has a lot of pride but is kind-hearted to those who gain her trust. Though it is rare and extremely dangerous, there have been humans who earned the privilege to ride her. She is the mate of Korborous the Lively, who is able to keep up with her in a race, and calm her when necessary. She is life-long friends with Akerian the Kind and Chiran the Brave, though their bickering often gets on her nerves.
