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.

Darkwing Duck is the self-proclaimed "Champion of Right" for this section of the cave. He is a very mysterious duck, as nobody knows for sure who is behind his shadowy disguise that he provides for himself by using magic to make other people see him as a duck. When he sees humans or scheming, villainous hunters, he swoops out of the shadows and strikes quickly, staying just long enough after for people have noticed him. He hopes by engaging in this dangerous kind of activity, people will be able to take notice and say his homemade phrase 'When there's trouble, you call DW', but thus far, he has few fans; his mate Rayrocae Moon and his daughter-sidekick Quiverwing Quack being the majority of them.
