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.

Week-Old Eggnog enjoys the "after-Christmas" events more than those happening before or during. She goes into dining halls and living rooms to eat leftover food and raids garbage bins and dumps for goodies humans leave behind. She also helps pull down decorations, which is a lot more fun than putting them up. The day after Christmas is particularly special because that is when the markets are busy, busy, busy. She heads to them to oversee gift returns and helps customers and proprietors calculate prices, tidy up, and keep people in line. For that, the dragon gets a share of whatever was being sold at that section. Week-Old Eggnog is immune to food spoilage, and many humans and dragons frown at her eating habits, but they don't try to stop her, either.
