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.

The cave's new broodmaster, Kunai lends himself and his fluff to warming any eggs or hatchlings around. Most of the other dragons are quick to recognize Kunai's usefulness, and shortly after laying their eggs, simply strut over and shove the newborns under his fur. This frees up the new parents to resume their duties, and in return, they are often happy enough to return from their hunts with extra offerings and 'bribes' for Kunai until their hatchlings are fully grown.
