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.

Thunder is commonly bullied by most Dragorians because she is half Pegasus and half Dragon. Although Dragons are enemies with Pegasi her parents were different. She is one the Dragorian Guard team. Her job is to protect all of Dragoria with her life. Her mother Thunderheart is the only Pegasus ever allowed into Dragoria and Thunder owns all of her ability to her mother, who also had served on the Guard Team. That is before her mother was killed by the Pegasi King(King Pegacorn). Thunder has since vowed on behalf of her Dragon side and fights bravely along side her father ThunderStorm.
