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.

Luken used to be a pillager. A hoarder of sorts. He would go around terrorizing innocent villages and would steal from other peaceful dragons' hoards. And when it came to fighting, Luken could find nobody who could match him. Luken slowly started going for larger and tougher Dragon hoards, and even tougher Dragons. And then, he met his match. He met a Fiery Red Dragon, and they had a long battle. Fire was shot and lightning struck down. Eventually, both dragons were left out of commission. Now, Luken is just focused on defending his hoard, and his unhatched eggs that live with him.
