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.

Dark green dragons, once they mature, appear to become an entirely different species. However, this isn't true. Rather, they burrow underground and get nutrients from their vines. These vines are sometimes referred to as Dragon Grass. These dragons are very violent, and will use their vines to capture, kill, and eat anything that moves, as well as nearby plants. Luckily, their range is limited and they cannot use magic. Dark green dragons tend to be easy to spot since they usually kill all plants around them and thus are usually surrounded by a large clearing.

Faolin is the first dragon to be raised by Sedragore, his caretaker. His name was inspired by the book series Eragon. Faolin, in the book, is an elf that dies tragically protecting the one he loves after giving her a flower grown by his magic. The dragon Faolin, with his love of plants, is named after him. Though violent and fierce, he has a soft spot for those he loves and will guard them to the death. He is also slightly introverted and has his own special corner of the cave. If you are keeping care of one of Faolin's children, he and Sedragore (his caretaker) would love to hear about them.
