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.

This breed of dragon was thought to exist only in legend. Although their name varies between cultures, they are often referred to as "Guardians of Nature." They are able to channel the forces of fire, ice and lightning, which allows them to wield tremendous power. Seen very rarely, it is thought that they only become active when something is threatening the territory they have chosen to guard. In order to protect their chosen home, these dragons are incredibly adaptable; they have been seen everywhere from remote mountain ranges, to ancient forests, to the darkest depths of the ocean.

Protect had been long awaited in Kaini's clan; but her arrival came on a day of terrible misfortune, and no celebrations took place. Pro did not understand it, did not understand the clan leader's sorrow. She was told by another dragon that a dear friend of Kaini's had left the circles of the world forever. In her wisdom, she knew little of emotion... but this, the great dragon understood. Pro decided then to take her duty as Guardian very seriously, keeping stern watch over the clan ever since.
