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.

Blue Tsunami long ago fell into the habit of pointing out the obvious. As a hatchling people, dragons, and whatever else was around, found this an endearing and cute quality. However, as Blue Tsunami grew older and matured everyone was less patient with this trait, calling him Captain Obvious behind his back. When, one day, he happened to mention a blue tsunami they should look out for in a nearby ocean, he earned the permanent name, Blue Tsunami. As he is calm, kind, and forgiving, he takes the history behind his name to heart, making special effort to keep his voice cut off from others if he feels he can't say anything except the obvious.
