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.

Yule was one of the dragons to arrive at the clan during the great Fractional Pie Day exodus of 36 AH. On his journey he had met several wonderful humans, like Shelybear, but in the end he arrived at Herk's clan and was easily convinced to stay with this ragtag band of chaotic individuals.

Yule loves nothing more than the holiday season. Like the Wrapping Wings, he loves to make things shiny and pretty but instead of getting into a competition with the resident decorating champion Sentimental, he prefers to use a little bit of magic to make his scales extra shiny and then spends at least three hours each night dancing through the sky, making the firmament glitter and sparkle. The hatchlings (and adults) love his displays and many diurnal members of the clan stay up extra late just to catch a glimpse of his beautiful displays during the festive season.
