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.

Green dragons are also sometimes called "earth" dragons. They usually live deep within caves, and have power over the earth. They are capable of launching boulders at high speeds, and can cause earthquakes by slamming down onto the ground.

Having collected quite an amount of pretty rocks and pebbles ever since she was an egg, Saphire now has an entire cavern inside the cave where she stores all her treasure. She greedily guards her collection every waking minute, letting almost no one get near.

The only Dragon allowed to visit her underground "rooms" is Angel, whom she has grown very fond of during her time of hatchling-sickness. She greatly looks up to the caring White and almost considers her a goddess.
