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.

Mimi Capella has a sweet, bouncy nature that makes the other dragons adore her. She is easy to please and is almost never seen with a frown on her face; she's so grateful for everything that she has. She is in love with Ebon Bass, though the two are unable to breed. They are married, but they have decided to allow themselves to breed with others, then raise the baby as their own. Mimi often wonders where she and the other Christmas eggs came from. This keeps her up at night sometimes.
