Dragons are creatures with nearly unlimited life spans. They can survive for long periods of time, and no one has found a dragon that has died of old age. Adolescence 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. Once they hit adolescence, hatchlings change quickly, maturing to their full forms in only 2 years.
Dragons don’t communicate with each other verbally, but they will growl to scare off predators and frighten prey. Young dragons will emit an extremely high-pitched squeal when they are frightened. To communicate, they use telepathy with each other and to speak to other creatures.
Christmas 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 Christmas.”
Sprig was named for his holly-like wings and green horns, though it doesn't fit him very well. After all, he is a noble Yulebuck, and as he would say, his breed helps make Christmas happen. He is mostly unliked by the dragons noted by his caretaker, as they think of him as 'the unlucky dragon that looks like a plant fell on the baby of a griffin and a reindeer' and his rather high-and-mighty behavior doesn't help at all. However, his exotic look and royal attitude make him and the Magi dragon, Sir Aed, on good terms and always willing to trade goods, with Sprig ending up with the more festive items and Sir Aed gaining any magical artifacts.
In terms of breeding and courtship, he has chosen the magnificent Sonnet Eirenne to raise children, although he may only have eggs of his breed once a year at Christmas time, the rest of dragons enjoy looking after the eggs in the short time before they are sent out to spread holiday cheer.
