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.

Krin'lar is the odd dragon out in regards to the warriors within his clan. Where his mate is boisterous and enjoys the challenge of battle, he is calm and quiet, killing any threat with deadly efficiency. Where the main warrior in his clan is strong and vicious, Krin'lar uses stealth and cunning to attack. Many think of him as gentle because of his quiet ways, yet the swift and silent manner in which he defends them can only be called lethal. More than one dragon has pondered the strangeness of this male as they watch him play so tenderly with his young one after dismembering the latest threat to their safety in such a casual way.
