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.

Aloof, acerbic, and laconic, spending most of her free time flying alone under the inky cloak of night, it seems hardly likely that Astoreth would win friends or influence others.  Still, she is one of the most desired of her clan.  She dispenses her favor rarely and with great deliberation, feeling that the pleasure of her company is an honor unto others.  Despite her seemingly icy heart, she would travel to the Underworld and back for those she cares about.
