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.

Ungula was found by Magicis' magic ability. Her clan abandoned her because she was a slow runner. She was attacked by a rogue ember dragon, leaving her leg broken. Incendium came just in time to fend off the rogue dragon. Ungula is eternally grateful to Incendium and Magicis because they both saved her life. She can't walk very far, because of her injured leg but she is extremely intelligent and often lies next to Magicis in their cave.
