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.

Dazien, otherwise called "Daze", is a typical young Daydream Dragon. But, there is one thing about him that is not typical of the usually passive and peaceful Daydream Dragon breed: he loves to prank. Getting a laugh at another's expense is a daily routine for Daze, but over time, he has learned the extent in which harmless jokes are no longer funny, through the discipline of older dragons. Now Daze merely keeps a smile even on the grumpiest of dragons through his antics. Most of the time.
