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.

In Dark-Flaming-Shadow's opinion, Iruthziel is a beautiful yet dangerous dragon. Most of the time Iruthziel is daydreaming or dropping daydreams. He is very curious on what happens in other peoples dreams and he knows whats happening in the daydreams most of the time. When Iruthziel was young, Dark-Flaming-Shadow had a hard time taking care of him because she would wander into daydreams all the time, but all her hard work paid off, Iruthziel has grown up into a beautiful dragon. Though from time to time Dark-Flaming-Shadow and her other dragons will collapse in daydreams when they are around Iruthziel. That doesn't make the dragons hate him because sometimes they need a break for the hard work.
