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.
Magelight Pygmy Wyverns make their homes deep under the earth, and produce a flammable, oily secretion from the tips of their tails to make light. The substance is long-burning, and brooding mothers douse their eggs in the oil while they incubate. Hatchlings’ tails subsequently catch fire at birth after coming into contact with their burning shells. Magelights are useful to human miners, as they are docile and easily trained to alert to the presence of methane damps, caved sections of tunnel, and proximity of nearby dragons to ensure the safety of crews.
