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.

Due to the lack of much ocean territory in Knowledge's clan, he instead makes his living in the rocky cliffs overlooking a large lake. He is a grumpy and independent creature who dislikes visitors, and tends to reject many habits that are otherwise normalized in his society. Though being antisocial and snobbish, he is willing to help out if someone is in danger or when called upon by the Clan leaders.
