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.

Vannen is a strong male Waterdragon who loves the wild and stormy sea.

Vannen decided to leave his birth-lake to travel through rivers until he reached the sea. His lenght is incredible, for he's able to make huge ships sink by wrapping himself around them and crushing them.

Vannen sometimes can be sadistic towards humans, though he never hurts women and children. He rescued a shipwrecked girl once, and is befriended to her ever since.
