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.

Sogyo never intended to be the leader of Nadat's cave, but somehow that's what she has become. Her respect for others translated into them respecting her, but sometimes the burdens of being relied upon become too much and she slips back underwater to drift away and relax. The blue and black depths reinvigorate her. After the swim she returns to the underwater level of the cave, pokes her head up past the water's surface, and patiently takes up the duties of leadership again.
