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.

Guardian dragons have large shields on the end of their tails. Although the shields appear to be heavy, they are light, yet nearly unbreakable. Guardian dragons use their tail-shields, as well as their wings, to deflect attacks and protect others. Often, they will guard the eggs and hatchlings of a nest while others are away. They are generally peaceful, and will not retaliate unless necessary. They have no need to forage or hunt, as they are fed by those they protect.

Although not a fighter, Nick Fury would do anything to protect his clan and his caretaker.

Most people dismiss him because of his quiet and defensive appearance and behaviour but his clan knows what he is actually capable of. Fumee might be the clans warrior but she listens to Nick's suggestions and orders. She had to learn the hard way that Nick Fury was not to be ignored when he talked about the best ways to defend the clan, even if he himself seldom participated in fights. After he had earned her and the rest of the clans' respect, he now coordinates everything regarding their safety and thanks to him the clan is now stronger than ever.
