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.

Grapevine is a quick runner and loves racing the fastest horses on hoof. She will allow people she knows well to ride her, although she can be rather skittish with strangers, and only Tiger can always approach her confidently. She's been known to drink enough wine at festivals to nearly kill a human, yet she never seems to get drunk, only to dull her senses a little.
