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.

Shadows Knight is one of the strongest warriors in the land. His dark magic allows him to transform into a terrifying shadow monster, greatly increasing his strength and speed. In this form he can not be recognised as a dragon and many who oppose him flee in horror.

Abandoned by his birth parents, Shadows Knight was adopted by a human girl who introduced him to the rest of the family and his mate, Final Valkyrie, whom he loves deeply. Should anyone insult either his mate or his human mother in his presence, he may lose his temper and kill them.
