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.
Hellfire Wyverns are so named for their foul tempers and fiery visages. Their social structure places all females above all males, due to superior physical characteristics and violent dispositions. Forced subservience of the males causes them to become vicious, petty, antisocial, and passive-aggressive compared to the aggressive and social females. However, orphaned hatchlings raised by foster parents of another species can develop surprisingly even tempers and mellow dispositions, proving that their defining unpleasant nature is, in fact, a learned behavior.
Nightfang Deathwing is quite friendly, due to her being raised by friendly dragons. A human would probably describe her cave as 'Gothic'. It is large and dark, made of black stone. Torches that burn with a strange blue flame are set at intervals around the walls, some set on stalagmites that protrude from the floor. Bones and skulls from various animals are set around the cave, some gathered from other places, some from fallen enemies, or those who tried to thieve from her hoard. She doesn't collect much gold, preferring gems. Her favorites are any big crystals, regardless of value. Despite her ominous cave, she's really quite welcoming to those who don't mind the creepy atmosphere.
