Holiday dragons are a very mysterious breed. They are only seen during winter, and even then it is hard to catch a glimpse of one. They are responsible for the general cheer that spreads during the holidays. In essence, they are the “Spirits 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.

Tainzer is much more jovial than his ill-tempered brother Blixem. He is often found prancing around the clan's cave, fluttering his wings and kicking his heels, working even the most taciturn of dragons into a more serene mood. He seems to delight in munching on Gaillen's herb bushes, much to the White's disdain. Tainzer does try his best to make up for it by helping to make Gaillen's special soothing herbal balls.
