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.

Araneos is the first born of the WM cave, and has become a natural leader of the clan. He grew up alongside Sarora and they eventually become mates. Araneos is strong-willed, somewhat stubborn, and at times acts as the conscience of the clan. He likes to think of the others more as siblings than clan mates, and actively takes a role in raising the hatchlings like his own children.
