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.

Seasonal dragons take on the characteristics of the season during which they are born. Thus, eggs that are laid in spring match the pink flowers and green buds of spring, and those that are laid in the summer grow to depict the bright green of the forest trees and the yellow of the sun. Eggs laid in autumn display the bright colors of leaves falling from trees, and those that are laid during winter take on the appearance of the icy snow.

Krystalix was born inside her cave alone. Ever since birth she was an outcast, always hiding in her cave and never seeing the light of day. As other dragons began to share her den, she realized what true loyalty was and dedicated herself to helping the younger, not wanting hatchlings to go through what she had went through. She and Bricade defend the cave in the morning, her on the offensive while he on the defensive. She is strictly loyal to Nightsheene's orders, as the black dragon is her senior. She can be quite stubborn at times but her heart lies true.
