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.

All Christmas dragons embody the Spirit of Christmas, but there's something slightly off about Haggis. He embodies the Spirit of SAD (Seasonal Affective Disorder). Haggis has a chip on his shoulder because he was born with bright red stripes, and all of the other dragons used to laugh and call him names. He constantly got into fights as a hatchling and quickly gained the moniker "Haggis the Fearsome" after defeating the scroll hotshot, Han Sum, in three consecutive schoolyard battles.

Haggis usually smells of strong eggnog, and he loudly bemoans his holly-leaf wings whenever he's drunk. He rails against commercialism and will completely trash any yard he finds decorated with neon reindeer.
