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.

After looking at the female infested cave Dorkbutt's master was beyond peeved. Finally having enough she vented on the poor little hatchling and let lose a string of curses that could make a sailor blush with shame. Pointing at the little dragon she ended her rant "You better gender a male you dork butt!"

Both Dorkbutt and his master blinked rather surprised when he gendered at that moment as a male. Finding the moment funny the last words said stuck to him permanently and eventually became his name. With a good amount of the dragons in their cave witnessing the dangerous moment few have ever had the guts to try and tease him about his unfortunate name.
