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.

Wolf of the sea got his name because of his fierocious nature, killing anything that moves either in the water or near it. The only being he doesn't fight is dragon reaper, who made a deal to move him to anywhere in the world as many times as he wants as long as he only fights or kills for hunting and self defence. But if he breaks this deal dragon reaper said she would put him in the styx river and never come back.
