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.

A brave but disagreeable dragon, Terregathow has been described as annoying by other dragons. She's not the kindest dragon of the bunch, and isn't what many would call 'forgiving'. Dragons must remember, however, her past was not the most... peaceful. When she was taken from the main dragon cave into the smaller cave of TerraDei's, she was a hatchling, unaccepted by her mother for having human scent on her. She wasn't very happy when she was taken in- in fact, she was furious. A stupid human, taking her only to abandon her when she had hatched, when she actually had feelings. Her two heads fought often, and she bugged all of the dragons. She still does, and all they can do is hope she can calm down...
