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.

Shentry is Elderen's wife. She is a devoted dragoness, who eases his soul from bloody thoughts or sadness. She fell in love with her husband for his shyness and sweetness but what impressed her most was his resolution. Shentry loves spying her husband when he's at work, but she takes a peek only when there's no seriously injured dragon (she's a bit scared of blood). She always helps Elderen cleaning his mind, keeping negative thoughts or distractions at bay. Her husband declares that without her help he would surely be lost. Shentry knows that is not completely true but she is very happy about it anyway.
