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.

Stone dragons have a tough outer covering made of a stone-like material. They eat rocks, using the minerals they contain for nourishment and to keep up their stone outer shell. They rarely move, and are the heaviest of all types of dragons. Although they have wings, indicating flight ability, no one has ever seen a stone dragon flying.

Folklore tells that if you find many rocks in a field, there is probably a 'mother rock' somewhere near by that is the source. Such a description fits Melilite very well.

She spends most of her days in boulder-like slumber, moving so rarely that moss has grown on her in places, earning her the nickname 'moss-belly'. Hatchlings of other breeds even tend to use her as a sunning rock. Several of her own children surround her... if one were to stub a toe against a large stone in her presence, a glance would likely reveal it as one of her sleeping hatchlings.

Melilite's offspring, regardless of breed, tend to relish their sleep. While seemingly inactive, they have a very active dream life... possibly even receiving visions of faraway places or insights into the past and future from dreams.
