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.'

All year long, Corelt waits in the cold snow of the mountain for winter to descend. An impatient dragon, when it finally does he bounds down to join the lair and frolic among them. He avoids the stone and black dragons for they are quick with their claws and teeth and he does not enjoy their implications that he looks good to eat. Instead he is happy to cause mischief with Sverre the silver and play pranks for the holidays. He is faster on the ground than in the air, and can outrace even the dorsals on foot. His favorite thing to do is tease stuffy Borentine, the other of his kind to call the lair home.
