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.

When water dragons mature, they lose their legs and the ability to survive on land, entering the water permanently. They are adept swimmers and eat whatever fish are in the lake they live in. They tend to inhabit the same lake for their entire lives, although a few live in the ocean and swim all over the world.

Procellia and her sister, Aquabi, were hatched by their mother in a peaceful lake away from all human contact. Her mother seemed calm at first, but proved to be emotionally unstable when her mate abandoned her. In her devastation, she abandoned her two hatchlings. Procellia and her sister were thrown into the world without any experience. They struggled to grow up and once the lake flooded badly, it seemed as if both hatchlings would die. Procellia and her sister were spared and survived the flood, then were taken into the Kalcea dragon Tribe and raised gently to full adulthood. Procellia takes after her mother's sensitivity a bit, though is much stronger. She will fight for her tribemates and is always there to lend a compassionate shoulder to lean on. Some dragons, including her concerned sister Aquabi, are afraid that Procellia was more shaken by their mother abandoning them that she lets on to.
