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.

Sarah Brightman has a wonderful and polite personality. Whenever the hatchlings go to sleep, she often tucks them in, under their leafy bed, and says goodnight. She likes the sound of music, and there is plenty of it when it comes to this cave. There are professional dragon singers everywhere. Even Sarah can sing to herself if she ever gets bored, and the other dragons don't feel like singing either. She's just pure lucky to end up in a cave like this one, where there is always the sound of sweet loving music, rock n roll, hip hop or many other styles. She, and most other dragons just love it!
