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.

Cleosebius is the oldest Sea Serpent of a close knit family of dragons, led by Dionysthenes and her mate Epitheus. Cleosebius gaurds the waters that run in the territory of his clan, watching for trespassing strangers that may harm the clan chicks or eggs. He is the father of two other sea serpents in the family, and has been lucky enough to breed with Dionysthenes during his first breeding season. Nowadays, Cleosebius continues to gaurd the waters with his offspring.
