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.

As beautiful as she may be, Wave is also a hopeless romantic dragon that has disobeyed the clan rules. The rule she broke "If thou beith a subordinate, thou shalt not mate with a dragon unless permission given by the mister and mistress." Meaning she was not allowed to mate with a male, she has mated with Neptune and now stands at the omega rank and so will her children.
