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.

gmBag follows the same deity that is spoken of by the dorsal For Gygax, though she is not as vocal about spreading the faith as he. Instead, she carries all manner of bizarre supplies that are related to the belief, offering to use them to help (or hinder) individuals who already follow it. These items include assorted polyhedrons marked with numbers, various odd books with information about all manner of things but that only seems to make sense to those of the faith, maps, little statuettes and snack food. How she manages to jug so much stuff around—especially on her occasional overland jaunts—is unclear. She claims it has to due with "taking some levels in monk". Most don't know what that means.

There is some suspicion that gmBag has been in a relationship with For Gygax. They certainly enjoy each others' company, disappearing for a long time when they meet. Some believe that all they have between them is a mutual love for braving the wilderness in the name of their god, however.
