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.

Tsunami is a dragon who can't leave the water. Her friends brag about how great and fun living on land is. Tsunami's family members are all underwater dragons. Most of them are happy with living in the water, but not Tsunami. He wishes he could hunt and fly, but the closest he's ever gotten to flying was jumping out of the water for a split second. Since he can't hunt, Tsunami spends his free time fishing.
