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.
Two-headed Lindwurms are a strange breed that are usually only be seen at night—especially when the moons are full and they feel their vigor is at its best for hunting. The rest of the time, these dragons are well-hidden deep within caves or crypts; they enjoy sitting in dark places. Each of their heads has a different mood and personality than the other, and since they have different brains, they rarely share the same thoughts—and never the same pain. They are so fully separated, one head can be asleep while the other is awake.
