Shimmer-scale Dragons are a very beautiful breed with small—but highly reflective—scales that shimmer and shine as the dragon moves through water. They don’t have fins or webbed feet, but their long, eel-like bodies allow them to swim quite fast. They were once rumored to carry large pearls in their claws—causing many to seek them out in search of this fabulous treasure. In reality, the “pearl” is of greater value to the dragon, for the fabled treasure is actually an egg carried by a migrating female.

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.

Herk the Shimmer is of the belief that she is a female dragon trapped in a male's body. She has come to terms with her situation thanks to Super Dimar, her mate. Because Herk the Shimmer is functionally male and Super Dimar a female in mind and body means that they are able to beget children without the help of other dragons. Herk is very protective of Dimar, especially since Dimar has a habit of eating gelato with sprinkles, and she ends up grabbing the wrong dish causing her to fall asleep in minutes.
