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.

Aeg is the original leader of the Jingle Lads. He used to live in the mountains with his parents and brother. His parents had always loved him more than his brother and treated him like an angel, leaving his brother to grow spiteful and neglected. Aeg moved into a lovely village and befriended a bunch of Holiday Dragons which would become the Jingle Lads. Originally, they were just a group that spread goodwill, but, then, Aeg's brother returned and terrorized the village. He killed several dragons, determined to enrage Aeg, and it worked. Aeg unleashed his full power for the first time, and the two's fighting nearly destroyed everything. Finally, they went into the mountains, where Aeg was thrown from a cliff, his brother claimed him dead and took over the town. Aeg was not dead, though, he had survived, but felt ashamed of himself for doing so much harm to others. He hid in the mountains, in the ice castle of Glacia. He lives with her, depressed and in anguish over his actions.
