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.

Plaisir's egg was first found when Embrase was enjoying his morning stroll one day. An egg that has been left for long was found, and Embrase had brought it back.

Although good friends with Aqua, who grew together, Plaisir is an exact contrast with Aqua. He is a relaxed dragon, interested in female dragons, and enjoying life. He is mostly peaceful and harmless. But sometimes, he gets into quarrels with dragons from other tribes and communities by flirting with dragons that are being fancied by other dragons.

Although other dragons worry for him, Embrase, who is most like a father to him, leaves Plaisir to be off on his own, for he claims that's what dragons like Plaisir are naturally like.
