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.

Hydrom, the first Water dragon born to the band, is the group's philosophical mind. He sits for long hours in the deep pool at the back of the cave, staring into the water, or out of the cave entrance. If he's not thinking above the water, he's curled up at the bottom, unmoving. The only signs of his presence are the small bubbles that reach the surface as he rests. What he's really doing, none of the band knows. This mysterious draco, however strange, has many insightful thoughts to offer the group. Conversing with his slow, calm voice, he often speaks in riddles. Alkin, the band's resident Black firebrand, regularly seeks advice on how to gain power only to find himself quietly pondering Hydrom's words for hours on end.
