Blusang Lindwyrms are quite different from most dragons in that they lack hind legs. In this regard, they resemble snakes, and this is evident in their movement; these lindwyrms slither along the ground, using their forelegs to lift them over rougher terrain. Blusangs are a coastal breed, preferring to live along rocky beaches and in seaside caves rather than sandy locations. They are omnivores who graze on seaweed from time to time, although their primary form of sustenance is fish.

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.

Tartness works for the human clan called Orglo, where he mixes basic healing spells and water magic of his invention to create a truly soothing, invigorating experience. Not only does it affect the creatures of the clan (the humans, their handful of livestock, and their pets), the package works on their apple trees as well. The Orglos have a vast orchard, and they compensate him with heaps of sour apples. He doesn't really like saying he works for humans, since every dragon he knows considers doing labor for humans undignified, but that's what the humans call it, and by GoN, Tartness loves their apple cultivar enough to accept it. For a while, he cooked his favorite dish by crushing the apples and mixing them with kelp, shrimp, and flatfish in the boiling waters of the town's communal spring, but after enough complaints, one of the neighbor families intervened and kindly offered to do the cooking for him in their home instead.
