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.

White dragons are pacifists and specialize in extremely strong healing magic. The only limit of this magic is that it can't bring back the dead. They only eat plants and never kill living things.

Mythrillius is a white gorgeous dragon. He is more than pacifist. He is hippie. And a bit of a playboy. He has lots of girlfriends and loads of children. Some of them live in the colony and some of them don't, he lost count really. The only child he is proud of more than others is Sneguro4ka, as she became a mate of Dark Dimond himself. He is breezy but very kind and sensitive. Sandrilyona used him as a peace-herald a few times, and in the clan that became his permanent position.
