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.

Floating in the clouds, Thwick gazes down on earth from above. If she notices any wrong done in the world, she swoops down out of the sky, and suffocates the evil doer with fog. The victim then is consumed by the fog—actually an animate mutated form of fo—fromr the inside out. The evildoer becomes part of the fog that will be used to save other's lives and smite people who have no good in their hearts!
