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.

Wood Hiew, or Hie, pronounced Hee, is Palacian Angaro's mate. They are both Pillow Dragons, and the only Pillow Dragons in the cave they live in. Like Angaro, Hie is late for everything but meals, and is usually asleep. However, she, unlike Angaro, likes to explore a little. She is the one who has found many tunnels in the cave, and these tunnels have allowed the enchantress that found them to adopt more dragons. Hie loves to help out in any way she can.
