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.

Fluff Huff has, to his mother's satisfaction, continued the "Fluff Heritage" as well as promised to continue it, assuming he will have a Pillow Dragon child. Fluff Huff rarely wakes, but when he does, he plays pranks on dragons of his cave. Of course, few suspect him because of how much he sleeps—he can't be awake long enough to pull a prank, right...

   Fluff Huff does not tolerate dragons sleeping in his fur when he himself is asleep. Unbeknownst to him, many hatchlings snuggle up in his thick fluff when he's fast asleep. Fluff Huff is relatively grumpy, but nice enough to have many friends. He gets angry when hatchlings crawl into his fur, when dragons tease him for his harmless appearance, and when a dragon wakes him.
