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.

Black dragons are warriors. They are strong and capable in battles of force, but also ample magic users, capable of devastating opponents with their spells. Their bright eyes give them excellent night vision, which is why they generally hunt during the night.

Princess Buttercup is the eldest of all the dragons in her clan, and therefore is one of the more respected amongst them. She is second in command to Tyrael and is their war general of sorts. She is quite hostile and tends to pick fights very frequently, greatly preferring the offensive stance to the defensive. She is certainly the fiercest fighter in her clan, and certainly feared throughout the entire land. Though she is primarily disliked, she is extremely loyal to those she does care about, Tyrael in particular. She is stoic to anyone except Tyrael and is quite short tempered, but she does fight fairly and is never cruel. Despite being a mother many times over, she seems to lack a maternal instinct and prefers to let others care for her eggs instead.
