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.

A Stone Unturned is a relatively active Stone, as he is always clearing boulders with Volcanic Sunset or expanding the cave by gouging away at the rock walls.  He is a grouchy young Stone, always harrumphing at the hatchlings when they pass him by; he frowns upon their 'childish' behaviour, wishing they would act more responsibly.  All of the adults in the cave consistently try to gently remind him that the hatchlings are just that: children.  Unturned often chooses to ignore them when his siblings speak so, usually bluntly reminding them that he can't change his views and they should leave him be.  Volcanic Sunset, his closest friend, is Unturned's polar opposite -- cheerfully quiet and positive -- and is always reminding the grumpy Stone to lighten up.
