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.

Undina is a friendly water dragon, living in the ocean with creatures called Undina. Tsu, a young undina and best friend with the blue dragon, was saved by the dragon when she was still small, so she named her protector after her species to honour him.<br/>They both love swimming through the great depths of the ocean and sometimes, they can be seen playing on the surface of the water.<br/>Undina was also the first dragon to hatch and grow up to Zafirmei.<br/>Tsu and the idea of Undina (c) Selene-soulwar
