Perhaps among the most venerated of dragon breeds is the Zyumorph, a breed whose selfless heroism and strong moral compass are nearly unparalleled by other dragons. Zyumorphs have an innate urge to fend off wrongdoing, and as such, are often sought after in times of peril. Although they are independently quite capable fighters, it is said that their true might is not unlocked until all six Zyumorphs are brought together in times of great duress.

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.

Swohn says he is a Mighty Swohn—it's like a swan, but "breathier". A few residents don't know what a swan is and assume that it's some kind of mountain spirit, an entity that even a zyumorph would look up to. The people who do know what it is don't argue with Swohn, since they see no point in doing so. Whenever Swohn appears, he's accompanied by hissing and snorting noises, the sounds that swans make (but breathier), and during leisure time, he walks around daintily, as if he were making his way across a sheet of ice. While he has many other quirks that people simply learn to deal with, the first thing everyone new to the territory learns is that he is a Mighty Swohn.
