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.

Swallowtailfail is an item deliverer for the Hearth-Hollow, Zihe Coppice, and nearby areas. She used to have just "deliverer" on her card, but she had to append "item" after Minister Stera hired her to deliver a talk about the eight divisions of Zihe and it went horribly. She's not affiliated with the mail office or the three other parcel services in the area, but if any of them asked her to move something on their behalf, she would do it. Because of her limited range and tough appearance, her delivery gigs usually concern locations that are hard to find or reach, like the cavern networks of the treacherous Multiples Slot Canyon.
