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.

Mystic Cloud is a dragon who is gentle and kind. He loves the puffy white clouds in the blue sky, which he always gaze at. He has a beautiful violet mane which he is grateful of. He enjoys the cloud that follows him everywhere. His personality is very similar to Dancing Snow's.

He loves to take long naps and loves to hear a beautiful melody along with it. Like Dancing Snow, he hates the loud and crazy noises around him and would love to live in a place full of harmony and peace, like paradise. He soars into the bright blue sky along with his cloud, flapping his wings until he finds a good place to rest that is filled with his likings.

He is also very quiet and almost never says a word. He sings a beautiful tune and flutters his mane to attract a beautiful mate when he sees one. He likes his own kind, so he always goes after the females of his own. He is picky about it as well.
