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.

Tonerre Violet's egg was said to have been laid in France and when he communicates, the voice of his mind has a heavy French accent. That goes to show that perhaps dragons can hear through their eggs.

Tonnerre is a very wise and thoughtful dragon full of stories... Once you get to know him. Before that, he's rather shy and doesn't associate much with the other dragons or humans. No one knows if it's because he lacks in confidence or because he thinks he's better than them.
