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.

Nefu is a Daydream dragon. He is friendly and nice but he's not quite popular with the other dragons for he often gives them fantasies and daydreams, this is especially bad if he spoils a hunt. Nefu usually spends his time in his own daydreams, going into a trance like state and just sitting there quiet, nothing can pull him out unless it's food, but few knows what his daydreams are.
