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.

Pillow dragons are covered in enormous amounts of fur affectionately referred to as fluff. Despite their deceivingly large size, they can still fly even with such tiny wings because their bodies are remarkably light. Pillow dragons have a habit of sleeping for up to eighteen hours a day, waking only in short bursts. During their few waking hours, they take the time to hunt for prey. Once a pillow dragon becomes an adult, its fur grows very slowly. Pillow dragon fur is used to make very expensive and valuable cloth known as "dragon cashmere."

A friendly, sociable creature, this dragon believes that the answer to most of society's ills is a good nap. Napping is awesome, and thus people who take naps are happier, and happier people are less likely to be nasty meanie faces! With this noble mission in mind, she is always happy to help another creature get a good nap, often offering up her own paws, fluff, and wings as makeshift pillows and blankets for them. Her kindness is well-known in the region she inhabits, and people often bring her presents as a means of returning the favor.
