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.

Navady fears others not of her family, and as such is a very rarely seen creature in the water, only appearing during brief interludes of solitude. She values her lake and spends most of her day gently swimming, making sure not to make sounds that would alert dragons and other creatures that are located nearby. Although incredibly shy, she will do anything to protect her adoptive family in the cave, and instinctively picks up any hatchlings that happen to fall into the blue liquid without first learning to swim.
