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.

This dragon is actually one of the first four of an army. Normally remaining as a row of stone statues in an abandoned castle, these Stone Dragons can actually be motivated to move when in a group of their own species posing as a shield if walking around an army group. If attacked using methods that could harm their hard scales, they will move at lightning speeds to attack such enemies, normally only seen moving for a brief moment, before continuing their constant, slow, walk leaving those they attacked in no condition to continue fighting. They have no names, as they are dedicated and raised for their purpose in war.
