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.

In Drow, her name means "water horse"—a fit name for her, as she was the first of her kind to join the clan. A rather timid dragon, Niar was instantly attracted to the strength of her chosen mate, Charnag Drathir. Though silly and prone to forgetfulness, she loves playing with and raising the hatchlings in the clan. She considers herself a surrogate mother to all the adopted eggs, despite raising eggs of her own.
