Khusa dragons thrive in dry, desolate, and rocky areas. Though they can fly, Khusa enjoy honing their climbing skills on foot. Shortly after they hatch, parents are already teaching their young how to pick their way across cliff faces, escarpments, and thin ridges. The young are well cared for by their parents, but other Khusa in the area also look out for the young—despite not forming close-knit groups, these dragons form loose alliances with their closest neighbors. If a threat is spotted, they will attack from above and drive it to the ground where Khusa have an advantage.

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.

Pieman bakes and trades pies. That's why he calls himself Pieman. Though he knows how to make the standard fruit and meat pies, no ingredient is off-limits except the species with whom he barters. No baking dragons, merpeople, or humans into pies made for dragons, merpeople, and humans (respectively). He has a total of 21 liaisons and resource handlers who represent him, so he rarely meets customers in person. He estimates that 88 percent of his customers don't know the identity of this Pieman they purchase from. Among human customers, the number is probably 100 percent. A lot of folks look at Pieman and think he's not the sort to like pies. He's even heard people out-loud reject the idea of him being a pieman, saying, "Khusa don't bake pies. It's not in the breed description."
