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.

Slimewalker is so abhorrent of starfish that he will not even touch the things. His mate Angelic Foot doesn't understand his starfish aversion, being a ribbon dancer, but nonetheless she obliges this mania and throws the tentacled terrors out to sea. He is very thankful for it, and is constantly making her all manner of trinkets, furniture, and structures to give her. The most impressive project he has created is a dance floor made of layer upon layer of hardened slime, upon which the two dragons spend much of their time. Slimewalker loves dancing almost as much as Foot, regardless of whether there is music or not.
