Glystere Wyrms spend most of the year deep in arctic seas. As winter approaches, these dragons will emerge from beneath the ice to congregate midair in search of a mate, where the glitter of mana crystals down their bodies can be seen as they fly across the night sky. Glystere Wyrms are known to take a respite from flying by looping around trees, over homes, or across high-hanging cliff edges while entwined with others of their kind. The colorful light of their mana crystals and the icicles formed down their undersides often leads them to be mistaken for festive decor when at rest. Traveling with friends and families to find the most brilliant display of these wyrms has become a steadfast tradition during the holiday season.

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.

Gyoketsu adores chorus music, and for him there is nothing better in the world than listening to a well-trained group of carolers during the holiday season. No matter where he is currently resting, if he hears the sound of a choir warming up nearby, Gyoketsu will always move so that he may better listen to their performance. Choirmasters in the area often combine their teams during the winter season, so that the shared voices may summon Gyoketsu all the sooner. While onlookers do marvel at his mana display, many of them listen for his voice: sometimes, if he is particularly pleased by the music, Gyoketsu will hum along. The warm, baritone rumble of his humming is said to soothe even the most troubled soul, and choirs who have experienced singing along with it say they are forever changed.
