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.

Bird Derg is proud and a bit capricious. She refuses to eat prey she deems too small—whether that be out of kindness or practicality is anyone's guess. Her desert lair is surrounded by rocks and debris arranged to form an obstacle course, which she traverses daily for exercise. She likes watching others complete it, and those who can do so who aren't khusas themselves earn her respect. Bird Derg loves meat and her best friend, Hostetler, who is made of meat. She hopes to eat him one day.
