It's been six years since Dark has left for the Lunar Imperium and much has happened with his growing family. With Twilight now a princess of her land and starting her own family things are looking up, or so they think. Dark forces have gathered and are now poised to attack the unsuspecting peaceful nations and their allies, ghosts from their pasts are ready and willing to destroy the peaceful world they once knew and rise from the ashes as its new leaders. Watch as Twilight and her family fight for peace and their friends.
