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.

"Yorru" is an alias, and few people know this dragon's real name. He basks in chaos, feeling it is the only acceptable "order" in the world. He is willing to take extreme measures but is not indiscriminately violent, nor does he feel any need to menace those who are no threat to him, especially those without magic. Along with his masterful manipulation of air and his physical capabilities, Yorru is innovative and charming: he can sweet-talk people to work out deals with him and allow him to wander around their territory, something often attributed to his natural daydream abilities.
