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.

Brian Bervirius is part of the Hellpack, a group of Hellfire Wyverns and Horses that live slightly separated from the rest of the flock. Having started with a few mated pairs made of one of each breed, they take in new wild-born Hellfires and Horses every generation, as mates for their Hellhorse offspring.

Brian is the wild-born mate of the second-generation Hellhorse called Bryll. He was brought to Hellpack Fort as an egg and raised as part of the group. His crush on the younger Hellhorse was obvious from an early stage, and he was delighted to realise that she at least tolerated him enough to accept him as a mate.

Brian is a member of the scouts, and he often ranges far to check for threats and to find more wild-born eggs to bring back to the Hellpack or, rarely, to the main AnselaJonla flock.
