Water Walkers are small dragons that are frequently found around bogs and ponds. While they are flightless, they retain the flight sacs and hollow bones of their airborne cousins. These traits, coupled with their extraordinarily long, webbed toes, allow them to stand on top of calm waters, using their small sails to propel them wherever they please. They spend the majority of their lives on the water, retreating to the tops of lily pads when the waters become too rough to float atop.

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.

Kugumi is a Water walker that's very tranquil at all times. He loves small flowers and holds an aquarium for raising plants on the surface of the lake. He lives in Buddhist temple and he works as a beneficial spirit that grant wishes. He doesn't communicate much outside Busan where the temple lies. He dislikes spies and informants, because they are vile and sneaky to him. In fact, he dislikes anything that is dishonorable and unfair. He cares a lot for those he knows well, the ones that regularly gives offering to Kugumi's master, a great dragon that lived for centuries there and had protected the village.
