Something is wrong in Equestria. Drug addiction, banditry, and war begin to consume Equestria and beyond. The order of the world has been shattered by something terrible. The world grows sick with a discordant union of reason and madness, sounding out the cacophony of the black, wretched things that eat away at the septic Earth. But two damaged ponies, Big Mac and Rainbow Dash, unwittingly stumble upon the source of these fractures in the world and their own lives. After discovering a true friend and kindred soul in one another, the two very different equines begin fighting to save the crumbling Equestrian Empire and the world.
