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.

If Serenal couldn't get fish at least twice a day, he would go insane. Whenever he has free time, he will go fishing and stack enormous piles of fish in his cave, but no fish has been in it more than three days. He has caught various fish: big and small, white and black, translucent and with all the colors of the rainbow. Some say he is the best fisher dragon of all Blusang Lindwurms in the area and he always agreed, until the fateful day he saw a a dragon tame a whale. Serenal never thought of fishing a whale, mainly because it is not a fish, but a mammal. He was intrigued by this powerful dragon and flew towards it to ask for the secret technique. But the dragon got startled the second Serenal touched her and flew away, making the whale drop into the water, making a huge splash. Yes, that was a lady dragon. Though Serenal saw her for only a second, the image of that beautiful dragon has imprinted in his mind. Now he fishes less and tries to find the amazing fisher female dragon.
