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.

Angel Dreamer Girl (ADG for short) comes from a far land. Her owner, Petpet, is an adventurer and ADG is always there to assist her when needed. She has the power of most daydream dragons but she's very protective and mature. Her clouds can carry her if she is too tired to use her wings. ADG normally stays in the clouds where she can daydream but occasionally, she'll go to a cave to visit other dragons or lay eggs.

ADG is currently a lonesome dragon and only cares about the ones she loves.
