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.

Kaeran is one of the quickest dragons in the cave. He is also as cunning as he is quick, and oftentimes is found drawing runes in the ground when he is not flying.

Because of his seemingly endless energy, Kaeran is usually the one to wake the cave members up for the day. He takes quick naps scattered about through the day so he doesn't have to sleep during the night, giving him time to do what he pleases.

Despite his childish nature, he is one of the oldest dragons in the cave. His younger sister, Karyann, watches him to make sure he doesn't get into trouble.
