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.

Sotoriska, a name from a dream itself, is a sleep-wanderer. He influences one's dreams ending with results such as a sweet taste in one's mouth after napping, a feeling of great delight at the smallest things, and an all around happy manner the next day. He does this unknowingly, however, and never realizes that he affects people in such a way. His only worries are trivial matters such as when is the cloud he floats upon going to dissipate.
