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.
To make up for a lack of physical strength, Fever Wyverns rely on a deadly poison—found on the spines covering the their tails—to help kill prey or to defend themselves. This poison will attack the victim’s nervous and respiratory systems upon entering the body, quickly rendering it helpless before eventually killing it. Usually a solitary breed, these dragons will only come together during mating season and will flare out the brightly colored sails along the backs of their wings to help attract potential mates. Although it has been observed that the wyverns are nocturnal, they will often pick an open spot of sunshine to curl up in and sleep as the day passes by.
