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.

Headaches is a severely moody, hormonal dragon, that often takes out her bad mood on other dragons.  She constantly fights with herself, though, too, both heads bickering at one another, scaring other dragons, both adults and hatchlings alike.  She also doesn't like to associate with other breeds of dragons, distancing herself to one side of the cave and hunting alone.  For a long time she wished for a mate, as well as other two-headed dragons to associate with, and now she's gotten her wish and mated with Vahus for life.  His dominant but kind personality often subdues and soothes her, and they are the perfect balance between one another.
