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.

Puffy is a playful and active dragon. She enjoys playing games, especially while meeting new faces. Highly social and affectionate, Puffy will approach any stranger with all the courtesy and repression of an excited puppy. She lacks any real sense of moderation or boundaries, often invading others' personal space without warning. She may even see it as a game, pouncing on others out of the blue just for a laugh. All of this does prove to be concerning since Puffy doesn't seem to register danger as quickly as she should. This means she must be constantly supervised in order to keep her safe, lest she get into serious trouble. This is easier said than done, however, since Puffy can be surprisingly fast on the ground. One minute she'll be batting around a twig or pebble, the next she's gone. She's been known to leave her babysitters baffled and exhausted, if not because of how fast she can disappear, then because of her seemingly boundless energy.
