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.

Holly King is the leader of the Holiday Dragons clan. He was the first holiday dragon in the cave. The can includes two Yolebucks, two full-gold wings Snow Angels and the new member of the clan, a Ribbon Dancer. As the leader, Holly King choose where the dragons go to eat and drink. The clan don't like every much the others dragons, they like to stay together don't matter what happens.
