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.

Two headed dragons are a special breed of dragons. They have two necks, two brains, two mouths, but one stomach and one main body. The two heads usually work together, but there are times when they will fight each other, attacking back and forth. They use their sharp teeth and wings to hunt large animals, and rarely eat plants. It is unknown what would happen if a two headed dragon were to mate with a one headed dragon, since it has never occurred. They only mate within their breed.

Although technically a member of the Ruda Clan, Windchaser the Feral seems more like a lone dragon than one in a group. Separately named Wind and Chaser, both heads of this dragon prefer living out in the territory alone rather than with the rest of the clan, going to meet with the group only when his presence is absolutely required. Few dragons, even those in the clan, really know anything of Windchaser at all. Only Alexandros the Unmoving, Talinia the Fierce, Gyatso the Forlorn, and the dragons charged with patrol and messenger duty have formed close relationships with him. To most of the other dragons, however, Windchaser the Feral is a mystery.
