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.

Stone dragons have a tough outer covering made of a stone-like material. They eat rocks, using the minerals they contain for nourishment and to keep up their stone outer shell. They rarely move, and are the heaviest of all types of dragons. Although they have wings, indicating flight ability, no one has ever seen a stone dragon flying.

Ratis is a very proud dragon. She can often be found standing at the edge of a cliff not far from her cave. There she will stand and watch over the land she has claimed as her domain. She rarely acknowledges other dragons for she believes she is of superior intelligence and can not be bothered dealing with "simpletons". She is of the opinion that few are worthy of her attention. The only other dragons she will associate with is her life mate Bhrigus and any of their children who choose to remain in the cave with her. She chose Bhrigus because like her, he possesses a superior intellect. In her opinion they are a perfect couple, for together they produce a rare type of black dragon.
