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.

Life is hard for a dragon that looks like a horse. Everyone is always trying to ride him. "Get off my back! I'm sick of these jokes!" yelled Agathodaimon at the amused dragons. "Calm down my old friend," said Satan laughing. "Ohh, please, just kill me!" added Agathodaimon, bored.

He is always assaulted by the hatchlings, who love to ride him. "Hey Agathodaimon, I guess you found your destiny. You're the perfect horse for riding." Agathodaimon was looking angrily at Satan, who loves to make jokes about this horse-looking dragon. "You better run, Satan," he yelled. "Don't forget, I'm faster than you!".

Agathodaimon may look like a horse but he is one of the fastest runners of all dragons. His wings are strong and big enough to fly all day without getting tired. Most of the time he patrols the surroundings of the cave, making sure no strangers are approaching. His horns are deadly weapons that must be avoided, giving him a great advantage in ground fights.
