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.

Seasonal dragons take on the characteristics of the season during which they are born. Thus, eggs that are laid in spring match the pink flowers and green buds of spring, and those that are laid in the summer grow to depict the bright green of the forest trees and the yellow of the sun. Eggs laid in autumn display the bright colors of leaves falling from trees, and those that are laid during winter take on the appearance of the icy snow.

Mossy is abnormally plump, almost to the point of being grotesque. Why, you ask Because he believes that he, like many animals of the non-Dragon variety, needs to hibernate when cold weather comes. At least, that was the excuse he used in the beginning.

Now he's so large that he seldom moves, and sleeps most of the year away in a place called Mossflower Forest. As a result, nearby Villages refer to him by the same name as the forest, and, believing him to be the Forest's guardian, offer large feasts to him in early Autumn, when he wakes up.
