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.

Thoughtless is a bit of an oddball. She was named Thoughtless for her habit of not really paying attention to anything, but she thinks, all right... but it can be hard to make sense of it. This strange dragon has been known to interrupt conversations and start chatting about some bizarre non-sequitor she came up with, as if she expects her audience to understand. Other times, she may be heard humming a strange tune to herself, or simply acting strange; her explanations are generally quite baffling. Tiamat is convinced that she actually does talk sense, it's just that only she knows the context; so far her attempts at proving this have failed.
