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.

Pearl is extremely friendly, like most of her species, and is much loved by human and dragon alike. She can dive considerably deeper than most of her kind, and has a greenish, pearlescent tint to her skin that is quite beautiful. She decorates her part of the cave with treasures she finds at the bottoms of lakes and in the shallows of the ocean—everything from pearls to entire tide pools.
