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.

The Beautiful Gem is a very vain and selfish dragon. She spends hours by a lake gazing into her reflection trying to fix her imperfections. If The Beautiful Gem is not by the lake then she is stealing other dragon's gems because she is entranced with their beauty, but she is too vain to dig for her own. If attacked by a random dragon, she would squeal at the horror of his or her dirty claws touching her scales, and then she would burst into tears. This would make the random dragon feel really sad, and then it would apologize and hastily retreat.
