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.

Neogranite has a rather gruff, unfathomably deep, voice that has occasionally shook loose boulders from cliff sides. His feet have accidentally crushed carts and small human devices that were left sitting around, unattended. His tail leaves deep ruts in the earth that are later birthing grounds for streams and rivers.

He is often referred to as the 'Gentle Giant', never really meaning any harm to anything he bumps into. When he sleeps, small creatures rest between his scales that make large burrows for them. They have not to worry about being woken up too soon because Neogranite often spends month in deep slumber before waking up and moving off to new places. It's a wonder how he even managed to fit inside of a cave as a hatchling, compared to the mountain he is now.
