When Water Dragons mature, they lose the ability to survive on land, entering the water permanently. They are adept swimmers and eat whatever fish are in the lake they live in. They tend to inhabit the same lake for their entire lives, although a few live in the ocean and swim all over the world.

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.

Water-fin, as a Water dragon, lives in a lake very close to the den of the rest of the dragons so she can keep watch on the rest of them. She is the one that will end up taking the hatchlings for rides around the lake, always careful to keep them from drowning. The other dragons are very grateful when she takes them out for the day since they get a rest, and can actually relax and do what they please.<br/>She is the thirteenth eldest dragon of Diru's.
