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.

Exodium, like much of his brethren, prefers a life of hostile confrontation with other black dragons to dictate and assert his own power. He is a solitary figure and enjoys resting in forsaken lairs when he is not actively fighting other dragons. When he wishes to remain anonymous, it is impossible to track him down as his onyx hued scales and wings help him camouflage in the dank lairs that he selects for his residential abode.
