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.

Thunderfur is the lightest and most happy-go-lucky dragon in the Arani tribe. Spending her days playing with the hatchlings and looking over the eggs (which she often does by floating in the air over them), she was never really one for battle. The hatchlings love her, especially her special fur, which all of them fight over to sleep with at night. Thunderfur seems to have never quite grown up—her love of play and mischief is still intact—but she will protect the hatchlings at risk of her own life.
