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.

Issei is very loud and very vocal, literally and emotionally. She is not afraid to show her true colors to anyone, even if it might shun them away. She has a high pitched voice that can grate people's ears, but when she's tired or in a good mood, she tends to purr. Issei can sometimes be a bit too bossy, but she cares deeply for her offspring and close friends. She loves howling at the moon, much to her neighbor's dismay.
