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.

Glyceryl, the winter dragon, is always noticed for her name. Glyceryl and her nestmates were being taken care of by a very unimaginative group of vines and poor Glyceryl was the last one to be named. While her siblings received semi-okay names like Big One and Little Tail, she received hers off the back of a lotion bottle. Apparently the dimwitted vines had run out of brain juice before it was her turn, and had just picked up the nearest thing and read from it. Her unusual name seemed to help her in the long run though. While the rest of the hatchlings forgot their dull names, she had always remembered hers.
