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.

Klikk is a very laid back dragon. He is content to move the rocks around his cave once, and leave them there. That is, unless his mate Vylea demands he move things around for a change of scenery. He can appear to be quite cold towards his young, but really is a loving father in disguise. He resents the fact that most of their young have to be abandoned to the rigors of the world and to known parents. However, it is the life of a dragon.
