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.

Gytha Ogg, mostly called 'Nanny' Ogg, can be very bossy at times but has one of those personalities that make her instantly likable; after only fifteen minutes, any dragon who meets her feels as if they've known her all their life. Whenever a dragon needs some advice, especially a mother dragon having difficulties with an egg, Nanny is the one to ask for help.

Nanny likes food and drink and male company, and freely shares her food with others. She also likes to sing, but most dragons wish she wouldn't share this hobby quite so freely.

Despite being fluffy and cuddly and only having one tooth left she is no easy prey; predators who are stupid enough to attack her will soon find out that she is tougher than she looks and knows enough spells to cover a Paper Dragon twice over (in very small writing).
