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.

Petite Douceur is one of the best friend of Douce reveuse, because she never shouts at her for sending wrong daydreams to the wrong person. But she is far more serious than her friend and only uses her daydreams as a mean to protect herself and the herd of people with bad intentions. She also does not like to take care of eggs and hatchlings, because she finds them boring compared to the conversations she is trying to have with other dragons and the humans that can keep their concentration when they get near her. She is very curious about learning, and is somehow the wisdom Douce reveuse does not have, while she represents her inside child.
