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.

This dragon is from the seas, somewhere, and seems a little secretive about his home. People would normally care about this because it usually means he's planning to make trouble or bringing trouble with him. The last time a mysterious being arrived and stated that where he came from and his history didn't matter, five hours later, there were monsters of indeterminate origin and sky rifts and some cane with a knob all raining destruction, and he vanished soon after the monsters and knob-cane did. Nearly every denizen has a story to tell when asked why they're wary of folks who don't give them any background about themselves. However, this colorful snake-dragon is just so jolly and bubbly when he arrives each year, and he's shown through multiple visits that he's no trouble, so an exception was made. He would announce, "Happy Holidays to You!" upon meeting new people and would give presents labeled such, and it took a couple of years to figure out that that is his name.
