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.

When The Biggest Dustbunny was only a small dragon; he enjoyed hiding under furniture. It didn't matter much when he was small, but now that he's fully grown, it tends to create a problem. Quite often, someone has come home to find that their bedroom is full of fur, while a dragon sleeps soundly with his head and front feet stuffed under the bed. Or perhaps they look in their kitchen to discover that their table is now pushed up to the ceiling because there is a dragon underneath it. Worse yet, they might find that a portion of the wall has been removed because he didn't quite fit through the door he was trying to get through, if he isn't still stuck there. The lucky ones are those who find nothing but balls of fluff beneath their sofas. It's not because they're bad housekeepers—it's just a sign that The Biggest Dustbunny has been visiting.
