Wintertide Dragons are a shy species that tend to be docile in nature. The leaf-like growths on their heads are rumored to have medicinal properties, though few have ever gotten close enough to test that theory. They maintain small groups in the mountains where they live, and rarely leave their homes in the peaks, aside from a short winter migration. The rhythmic chime of their feathers and their melodic wails are often considered to be the ballad of winter.

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.

Yuki grew up in a dense forest, bordered by a few human towns. Though he primarily kept to himself, he couldn't help but venture out in curiosity every once in a while, when he heard the ringing of bells that he found particularly charming. It took a few weeks for him to find the source, but eventually Yuki found that the sound came from a string of metal chimes tied over a wishing well. Every time a wish made at the well came true, the wisher was expected to ring the bells every day for three days. The sound has always made Yuki quite happy, so he's recently moved his living cavern closer to the town so he can hear the bells more clearly. Sometimes, if he's feeling rather jolly, he will flap his wings so his feathers chime in reply to the bells.
