Ridgewing Dragons live just below the snow level on the upper slopes of mountains. They are a friendly, playful breed and enjoy dancing in wind currents near their homes or plummeting down into valleys from great heights. Their wings, by far their most striking feature, grow in fin-like ridges along their backs. While their bodies lack markings to blend better with their surroundings, a ridgewing’s wings have bright markings in the colors of the flowers that grow in their mountain habitat. Occasionally different-colored individuals can be found, but they are rare because their striking coloring offers little protection.

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.

Jasai had grown up side-by-side with Sleir, the other Ridgewing inside the castle. She was, however, much more modest than Sleir. After his "accident" she kept a very low profile inside the castle, not wanting to end up as mutilated as her counterpart. Often she waits until night before going out, and is punctual about returning before sun rise. Graxe, the Pink who loves to read, once told her she reminded him of a princess he once read about, who always had to be home before midnight, and was forced to hide away from the world. While it might have intrigued her once, it now only makes her envy the princess; at least she got a happy ending.
