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.

Aozora is named for the blue skies when a day is at its clearest and brightest. He adores his younger (by scant seconds) twin sister Yozora and both are rarely found apart from each other. One often sees him lazing by the riverside as Yozora frolics around in the water. He is the more mature of the twins and less inclined play the day away but for Yozora he'll suffer anything. Well, at least until she destroys his seaweed garden. Yet again. For the billionth time.
