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.

Duke Promise is a very influential dragon, known for his kindness and pure heart. He has an unlikely friend, Wisc, who is cruel to others but is kind to him. Duke Promise is pretty oblivious to other people's faults, and that's why most dragons like him. Most of the time, one could find him either hanging out with Wisc or voicing his opinion in the Queen's court.

  Duke Promise lives in a mansion in the sky, and owns a very large hoard. His hoard is made up of many things, including magical potions, golden lances, and platinum coins. Most of his hoard is actually gifts from other dragons.
