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.

S.E. is amazingly smart for a daydream dragon, always at the ready with a solution for a problem or a witty quip for anything else. Her dark purple mane is tied up in thousands of little braids, and she has a spiraling tattoo that starts around her right eye and ends at her front leg on the same side. She is mated to Satchell, Mesconna's Godfather, and the pair travels around the world in search of friends, adventure, and the perfect scrambled eggs.
