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.

Vinimire, is a dragon who all hates humans, but his owner most of all. When Vinimire was stolen by someone who had never even seen a dragon before, and needless to say wasn't a very good owner. He was his owner's first ever egg, and was not properly taken care of. Yet despite being an unhealthy egg, he somehow managed to hatch. His owner had been expecting something better than, so Vinimire was released only to be found again, through some quirk of statistics, by the very same owner who released him. This time though Vinimire was left to die with no food and no water, while his owner went off to raise other dragons that all died before hatching.  One day his owner decided it was high time to clean up the soon-to-be rotting corpse of  Vinimire, only to find that Vinimire had become a fully grown dragon. Nobody was quite sure how Vinimire managed to survive, but they were sure it had something to do with the distinct smell of blood in the place where Vinimire was left.
