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.

Devious Daydream is a kind dragon. He uses his power of daydreaming to make it easier to catch prey.

She had always looked up to him,and he had always loved her with her beauty. They seem perfect for each other. When Devious Daydream isn't out hunting, he plants daydreams in the hatchling's heads. He mainly planted daydreams of adventures, and fighting.
