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.

Meliene is slightly more active than the older Pillow dragons, but only because she is on a mission. Her quest is to find the most comfortable spot in the house, so there are very few places she hasn't been found sleeping.

This has caused her Cave Mistress a great deal of worry when she naps in some hidden spot, such as in the chimney or inside the rubbish bins, as her human mother constantly worries for the little dragon's safety.
