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.

Cloak of Shadows, or Shadow as he is often known, has a reputation as grumpy and brooding.  He had a difficult childhood; he was abandoned and left to die as a hatchling because he was not an alt, but was taken in and taken under the wing of Kaida the purple dragon, who brought him up to be proud of who he was.  Despite this, he always feels he is not good enough, or his parents would have kept him.
