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.

King Lucius, despite what her name suggests, is in fact female. Her name came about through a mistake during her hatchlinghood, for she was the first in her clan to be hatched. Lucius is the undisputed leader and protector of the clan and can always be found wrapped around the entrance to Clan Cave with her great wings folded, guarding her vast foster family. Above all else, Lucius is objective and logical. Her quiet, even-tempered tolerance makes her esteemed by even the most belligerent of the clan and a strong base that all can turn to at need. She is fond of her clan and enjoys her station, especially because she is not required to move often. The sight of a giant stone dragon with glowing red eyes perched above a cave entrance in the fog generally makes any casual visitor strongly consider turning back more often than not. The Clan Cave, in which Lucius and her clan lives, is in a group of cliffs located a short distance to the west of the original Dragon Cave.
