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.

Reindeer Delta is a devoted dragon fan of Graceful Delta, the only difference between him and the other dragon fans is that he doesn't disturb her. He just leaves food and water next to her in the morning before she wakes up. One might ask him if he was in love with her, and he'd say no but his heart says otherwise. He hopes that one day, Graceful would notice him. Other than that, Reindeer is a cheerful Christmas dragon. Reindeer Delta is a born member of the Delta Clan.
