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.

Loch Crusoe is a fairly small blue dragon who loves nothing more than running across the water's surface or hiding underneath one of the waterfalls. He is a prankster at heart and takes great delight in soaking the Keeper, or any of the resident dragons with water every time she, or they, pass the lake or whatever stretch of water he happens to be in. He is extremely good natured and loves to please, happiest when others are happy. He is the head of the aqua patrol within Quill territory and it was when he was just resting after a day of patrolling, and pranking, that he met his mate, Goldstreaked Aura.
