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.

The first born to the owner, Rockslayer is a fierce dragon when provoked but tries to be as peaceful as possible. His textured skin allows him to blend in with the environment, masquerading as a simple boulder. This feature is especially useful when he hunts, as the average animal will simply mistake him for a rock. He then catches, kills and devours the animal. He is extremely quick and efficient making it difficult to even prove he ate something... this worries his master from time to time
