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.

Hroc is a little odd. Unlike other Black dragons he hunts during the day yet he is always gone during the night. It did not take them long to figure out what he was doing. As his songs rang out clearly. He sang every night and what beautiful music it was! He sang about what he truly loved, nighttime. The moon, lone wolves howling, and the predators of the night all made it into his songs. He is not shy about his singing though. If someone would ask him to sing he will gladly do it, but he never takes requests. He always says his songs come from his heart and if he doesn't like what he's sing about his songs would sound horrible.
