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.

Despite being a very romantic male, Pulsate has never been able to successfully keep a mate. Of the females who have mated with him in the past, none stuck around with him to have a second egg. Instead, they have moved onto other males, claiming that Pulsate is just too clingy and emotional. He can't help it—he tries to be romantic and charming, but the constant fear that he will be abandoned torments him, and he ends up getting too attached too quickly. His attempts to keep a mate end up driving females away—it's a vicious cycle, and it has happened to him three times. After the third female bred an egg with him and promptly left him, Pulsate gave up and decided he needed to be on his own for a while. He is still waiting to meet a female who can handle his neediness and strong emotions.
