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.

Reynoso lives in a city with lots of humans. Most seem surprised he's here due to knowledge of his breed, but he doesn't know much about the khusa breed since he was the only one in his family. He's one of the denizens who lives close by Crap Creek, since he has a strong stomach and doesn't seem too fazed by the smell. His job is to sweep and scrape the roads clean and dump the waste into the creek, so living by it is convenient. He's been jailed a few times for climbing buildings and accidentally damaging them, and the occupants of those buildings really don't like him. Despite those issues, this arrangement is much better than life with his clan before. Reynoso was kind of an oddball in his mixed-breed but all-unpleasant family, where members acted outwardly pleasant but took every opportunity to try to screw each other over. When his beloved nana died, he was the only one who mourned while the others considered their day spoiled by his stupid crying.
