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.

Kyuuketsuki Densetsu simply loves to devour bad description reviewers. In fact, this description is simply his 'menu', in a way. He reads every comment slowly, savouring the process...picking out his next meal. When he has chosen the most pathetic out of the lot, he flies out of Halo's cave, seemingly just a big black mastiff, albeit one with wings.

He pays the reviewer's home a visit, and for a few seconds, nothing is heard but screams, and the slow crunching of bones.

When he finally takes his leave, he always remembers to leave behind a single bone- A skull with the word 'noob' engraved upon it.
