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.

Frozen Heart is a very deceptive dragon. His handsome appearance may fool you. Frozen Heart has no set mate, as he often just charms another dragon's mate, breeds with them and then abandons them. His name definitely suits him, as he has no care or respect for others. Frozen Heart is one of the rogue dragons in the area—the rogue dragons being dragons that have been exiled from the main village and cave areas due to bad behavior or their risk to others' health or mentality. He regularly duels against other rogue dragons, such as dragon number thirteen (who is called From The Depths of Hell) and the two hellfire dragons. Frozen Heart is looked down upon by all non-rogue dragons. He hopes to be able to group the rogues together and take over the main parts of the land he has been excluded from.
