Discord was the true ruler of Equestria. The real Equestria. The ambitious Celestia didn't see Discord perfect reign of chaotic happiness, so she overthrew him in an apocalyptic event. This, was the true end of Equestria, when the king was imprisoned into stone. Today's Equestria is merely a mask, a post apocalyptic scene under the guise of Celestia's tyranny and need for control and constants. Now everypony has to control everything, the weather, the animals, the light. The "Equestria" we see in the present, is in fact, not the true Equestria. The true Equestria was destroyed many years ago.
