Six months after the mess in Tambelon with the Mane 6 and Avatar Korra, the Power Ponies find their world on the brink of peace. Despite the loss of Anar D, the Power Ponies and the Mighty Machines still work to make Equestria a better place without anything getting them down. But when the Sisterhood of Justice threaten the Maretropolis, the heroes go after them to stop them. But during the battle, they find themselves in another Equestria, one that doesn't have any sunlight, any heroes... and no hope. Our heroes find rough hardships and tough choices and unexpected surprises. While the Power Ponies' princesses work on a way to bring them back, our heroes have to free the world they find themselves in and find a way home by defeating the sinister ruler of this Equestria, the Negahorn.
