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.

From the time she was a hatchling, Aquatiis has been asking the same question, "What am I." She's not completely a fish, and not completely a dragon either. The other dragons regard her as some oddity, a weird hybrid, and she struggles to fit in. The water is the only place where she feels she truly belongs. Where she can feel like she is flying like any other dragon. Where everyone will except her without question.
