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.

Tempestuous Sea is a rather calm, peaceful dragon. Being submissive, he usually endures the frequent tantrums thrown by his mate, Torrent Leviathan. He also prefers to be alone. This cave's keeper noticed once that he did something one would usually expect from a cheesy comedy: he built a wall down the middle of the lake he shares with his mate.

These days, he typically begs Mint Scouter to find a second lake for him and his mate to live in, preferably one with a few undersea caves. So far, he hasn't made much progress.
