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.

Pond is very serious and stubborn. His mother was Terror of the Water and hates humans, and Pond has been raised to think that they're horrible creatures. He used to look up to his older brother, Water Which Flows, until Water became friends with a human. Now Pond despises him, and thinks he's a disgrace to the family. His son is Waterfall Splash in Water, and he tries his best to teach Splash about the "horrors" of humans.
