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.

Kuriiro Hakujin Yukiyama, meaning Maroon Whites of the Snow Mountain Family, is a cheerful dragon despite being generally unaccepted in her community. Besides her longtime friend Yama Kokoro everyone thought her odd for being a normal ridgewing dragon and having both her parents be alts. Kuriiro simply shrugged off the remarks and ventured outward where she met Yuki Moyasu, who shared a similar background as her.
