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.

Aquaizi is the main water transport for the Advocate of the Dragonreaper. While the Advocate needs the aid of Aquaizi much less often then Kazaka, the relationship between the two is still considerably stronger than the Advocate's relationships with other dragons.

Aquaizi spends a great amount of her time teaching the hatchlings how to swim, and playing with any other dragon taht has the spare time. It is not terribly difficult to coax Aquaizi out of the water if there is a game to be had but doing it too often makes her begin to feel out of place. This is quickly remedied by playing water sports in her element.
