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.

Def's way to fly seems almost impossible to human and even most dragon onlookers. The way he effortlessly glides even with his relatively small wings, the way an almost invisibly small adjustment of the tail changes his course, and of course the way he dives into the waves to catch a tuna, breaking the surface a moment later with his prey between his teeth, rising unhindered by the added weight.

An educated onlooker will of course know that this is only possible because his flight is aided by magic as much as by his wings, but Def's skill is nevertheless impressive.
