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 is a mild sociopath who loves nothing more than ruffing the feathers and scales of her reptilian "comrades". She tends to value other creature based on how amusing they are or can be to her, so she fluctuates between social circles frequently. Caustic, sarcastic, and purposefully malicious, she thrives off humor and word play, but can hurt people more than she intends to. Not fond of males, she keeps a few around for entertainment only, but is genuinely close with Ourros and Hanky Pankie. Wild and erratic, she's the type that other fear but are fascinated by.
