Discord, Spirit of Disharmony, God of Chaos & Entropy and a nice addition to the Royal Sculpture Garden. Swift Thought, former student of the Royal University, first and only democratical theorist in the history of Equestria, now Canterlot's foremost hobo. When the latter decides to take an illegal midnight stroll through the Royal Sculpture Garden, he finds out that not all the statues are just silent chunks of marble, as the frozen form of the Spirit of Chaos offers him a deal: he will take a hitch on Swift Thought's mind, lend him a bit of his powers, and together they will make an incredible journey around Equestria, to ask the old gods of ponykind, now lying forgotten and forced to live among the mortals help to beat Celestia and Luna and finally, after three thousand years of monarchy, transform Equestria in a democratic nation.

Whether they like it or not.
