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.

Midnight's Blue Aura is part of the original trio of the LeValle clan, is Winged Spring Leaf's mate, and is also adoptive father to Kurai and Moonstar.

He and Winged Spring Leaf were a happy couple who one day found a lost Nebula dragon and decided to adopt him. This day changed their lives forever and caused a domino effect, leading up to a whole clan being formed.

He currently resides in a cave located under a lush, beautiful hill along with the rest of the clan.
