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.

Wet H2O has recently discovered that water is wet. In fact, so is milk. Actually, a whole manner of things are wet, though some of them stop at damp.

"With my intelligence," Wet H2O often muses to herself, "Other dragons should not be able to laugh at my ingenious discoveries so. Apparently my knowledge is too advanced for the simple dragons I am forced to keep company with."
