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 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.

Deep in the Cave, there's a huge lake where Silwen Falaron resides. Seirye found her egg one day laying on the cave's floor, just after she had discovered the lake. Her dragons frequent the lakeside, as Silwen is much fun to be around. Her mate is the Magi Puuf the Magic Dragon, who is as happy by a lake as he is by the sea. Silwen is very social, and she loves to talk to the other dragons. For the hatchlings and the more insecure, she's a best friend who will listen to anything they have to say and never repeat a word of it.
