Sweet dreams are made of this...
Who am I to disagree?
Travel the world and the seven seas...
Everybody's looking for something.
It's no secret that Equestria has been the current habitat for various lifeforms, like and unlike them, even before its establishment over a millennia ago; in fact, one of which is a draconequus, a serpentine chimera composed of various anatomies belonging to other creatures yet identified as one of great power: as such, the lifeform in question needs no introduction whatsoever.
Called Discord, he's known as one of the most ancient of adversaries faced by the Equestrians themselves, especially by their rulers, Celestia and Luna: once upon a time, they'd both sealed him up into his stone imprisonment through the usage of the Elements of Harmony, the very same artifacts used by one of their students and her five friends to end his short reign of terror.
Although freed from his petrification thrice, he no longer has any desire at all to subjugate or seek revenge but many have known about it far too well; what remains unaware to themselves is the fact like most, if not all, creatures sleep on and throughout a fraction of the day though in his case, the innate abilities he’d possesses seem to have little to no effect compared to being awake.
