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.

Water walkers are small dragons that are frequently found around bogs and ponds. While they are flightless, they retain the flight sacs and hollow bones of their airborne cousins. These traits, coupled with their extraordinarily long, webbed toes, allow them to stand on top of calm waters, using their small sails to propel them wherever they please. They spend the majority of their lives on the water, retreating to the tops of lily pads when the waters become too rough to float atop.

Kitanai Mizutamari's name roughly translates to "dirty puddle."  Mizu's domain overlaps that of the serpentine dragons of the lakes, though as a smaller dragon he more frequently occupies the smaller pond offshoots.  He is somewhat shy, using his natural camoflage to hide from the humans who share his territory.  Mizu mostly avoids the other dragons, knowing himself outmatched physically and not always trusting in the others not to challenge him.  On those nights when the other water dwellers are celebrating some thing or another, he has been seen hanging on the fringes, perhaps attempting to mentally overcome his fear.
