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.

"Ssinjin Verin" is the drow elven phrase for "Sweet Evil". She is very playful for a black dragon, but tends to underestimate her physical strength. As a young female Ssinjin would love to play with the other hatchlings, but her sheer power would injure them severely, so she has to keep herself from doing anything stupid.

Her mate is Veldrin, Faeryls first black dragon, who is always kept busy trying to keep her occupied with something. They often spend their days outside the cave, play-fighting in the near mountains.
