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.

Mystical Dreamer enjoys messing with peoples minds. The only human he does'nt mess with is his master's, instead he gives her dreams that his master would enjoy and keeps his master's mind at ease because of how well his master treats him and the fellow dragons. Anyone else's (unless told not to by his master) mind will become a blur and will experience various unnatural thoughts and emotions which Mystical Dreamers is always experimenting with.
