Daydream Dragons are the hosts of daydreams and fantasies. They spend the majority of their time sitting on clouds, dropping daydreams down into the minds of people passing by. Humans who live near Daydream Dragons must be especially careful not to let their thoughts wander, or they could end up spending hours or even days in a trance-like waking dream state.

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.

Doragon Musou is a Japanese name meaning Dream Dragon. This dragon is very scatterbrained, and often loses her train of thought. She spends most of her day on a cloud above the cave, dropping daydreams on all the dragons and humans below. Her favorite thing to do on April Fool's Day is to create daydreams for everyone that make them bump into each other.
