Water Walkers are small dragons that are frequently found around bogs and ponds. While they are flightless, they retain the flight sacs and hollow bones of their airborne cousins. These traits, coupled with their extraordinarily long, webbed toes, allow them to stand on top of calm waters, using their small sails to propel them wherever they please. They spend the majority of their lives on the water, retreating to the tops of lily pads when the waters become too rough to float atop.

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.

Sigma is a polite, unassuming Waterwalker who loves to happily 'skip' around the surface of the water and snap up small frogs, which are her favorite treat. She is good friends with many dragons who study magic, and she lets them test less harmful spells on her- this has resulted in her building up a bit of magical ability herself, which she mostly uses to zap frogs so they can't get away.
