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.”

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons 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. In Galsreim, dragons and humans coexist peacefully.

As his name implies, Delicious Sleep is fond of sleeping. He is so fond of sleeping that he takes nearly every opportunity to sleep. When another dragon or even a human speaks to him, he'll seek every opening to let his heavy eyelids droop and shut. Thus, he is left alone by many.

But he is not lonely. When he was a hatchling, he was quite too energetic and too enthusiastic for many of the others to endure his presence. However, he met a friend, his best friend and future mate, in another pillow dragon called Delicious Pillow. Her own sleep was continuously interrupted by this previously young hatchling, but she never snapped and never grew impatient. Now, the two spend their days napping throughout the seasons together, protected by the humans who collect their soft and cashmere fur.
