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.

Essdi is lanky and soft-spoken, with a pale mane. A foreigner to the territory, he was assumed to have fled his homeland due to natural disaster, or more likely, dragon-made disaster. He wouldn't say anything about his previous life, and his quiet, unassuming nature fueled more gossip about who he is, what he's planning, and why he chose territory that was occupied by dragons he couldn't have known were friendly. He lived on a dried lake bed with the most colorful hoard anyone has seen, mostly composed of smooth and round objects whose original purpose was as inscrutable as he. After roughly two scores, where Essdi befriended a handful of dragons and all thought he would be a permanent fixture, he departed one day as suddenly as he arrived, leaving all of his belongings behind except things that were gifted to him. Those who believe he's no longer alive say that his ghost visits the dried lake and sits in the dip where his hoard was kept.
