Waterhorse Dragons received their name due to their horse-like physique and endearing behavior. They are capable of surviving out of water, and when on land their skin secretes a gelatinous goo to retain moisture. However, their large paddle feet are better suited for swimming, and waterhorse dragons tend to move very awkwardly when on land. Waterhorses are very friendly dragons and enjoy playing with humans.

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.

Mowam Tobah, often referred to as just the first or second part of his name, is a level-headed and lonesome dragon. He, being raised during a war between the humans and the dragons and having to fight in it, doesn't like humans. He has seen a great many killed by them, not to mention lost half of his tail because of them, making him not at all hesitate when it comes to fighting them. As the war was ending, his mate, a very powerful fighter and leader of his clan, was killed in an ambush. The war ended before he could exact his revenge on a human capital, so he instead took residence in the Resistance Bog, which is a small settlement that will fight even after the war has ended. He refuses to find another mate, for he feels that he has not avenged her yet, and never will.
