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.

Wathnkor is a waterhorse dragon, like his mother Eerth, while having a shape of a horse more like to Lambukor horsedragons, like his father Ashkore. Although he did not the same hooves of his father, he is not so clumsy on land, like the other dragons of his kind and he's a good swimmer. It has a docile behavior of his mother, even if it is a good hunter, due to the teachings of his father's Ashkore.
