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.

Dunbold doesn't seem to understand that she can't walk into other peoples' homes whenever she wants. She'll wake to hunt briefly, then wander into the nearest den she can find and promptly fall asleep. She's very difficult to wake, leaving her host utterly confused as to what this unresponsive stranger is doing in the middle of their home. The next day she'll awake, go hunting, and then wander into some other unfortunate sap's house as if its her own. The only thing known about her is that she hates the rain.
