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.

Unlucky people might find this dragon on their travels, sitting on the broken remains of a stolen chair, slapping the strings of a waterlogged guitar and singing (terribly) about someone named Susanna. Nobody, not even his family, knows who the Susanna in question is. Those who listen to him long enough will hear him sing about someone named "Al Abama" and "Louie Z. Anna", and no one knows who those two are, either.
