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.

Erpheon Darkbringer comes from a long but mixed lineage, and like many half-breeds, was only grudgingly incorporated into the Highdrake Clan. However, perhaps the others had been right to be cautious in letting Erpheon in, for he even had the audacity to denounce the clan and its leader in front of the Council, stating that the discrimination against him was unjust. Although his heart might be in the right place right now, there is no telling that he would not end up malignant.
