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.

Donnamira is a very motherly dragon, acting gently yet protectively towards many of her scroll-mates. She lives within the tunnel system dug by her life-mate, Elenion, with her mate as well as her son, Denethor, and his own life-mate, Adara. Donnamira tends to spend most of her time grooming her dragon-grass, tidying up the tunnels, conversing with her fellows above ground, or passing time with her small family. Though Donnamira is quite kind, wise beings will usually stay away from her dragon-grass. She is most proud of it and gets snappish when she finds that anyone but her or her mate has even touched it. Donnamira was the eighteenth dragon to be listed on Vinr's scroll.
