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.

Gold dragons are the ones most often killed by humans, who consider their scales to be extremely valuable. These golden scales grant them a high level of protection, similar to armor, and they use this to their advantage in battle.

Gilded Nightmare is the offspring of a female gold dragon and a nightmarish male black dragon. The strange unity produced a dragon with the beauty of his mother and the temperament of his father. His fierce attitude has helped him to survive over the years, for his golden hide makes him at high risk to be hunted by greedy humans. Other dragons sometimes get more than they bargained for when they attempt to interact with him, not expecting his short temper. Over time, he may adjust to the safety of his cave and not be such a nightmare to others.
