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.

When Feel-Good receives a new thing, he'll shake it as a child does a present. Some people have introduced him to "handshakes" wherein he shakes their hands rather than their whole bodies. One village shop's clerk described a thick beverage made with dairy and sweeteners made by shaking, called a "shake", and she demonstrated for him. Feel-Good thinks this term is a little confusing. When he floated the idea of punishing whoever invented that vague word, the shop lady quickly said it wasn't her. Feel-Good's nest-brother also likes shaking things, but Feel-Good hasn't seen him for a long time and sometimes misses shaking things together with him.
