Fifteen years after the coronation, a fierce military-based government takes over Equestria. They slaughtered the princesses and kept Twilight hostage. They threaten to find and kill all of Twilight's friends (except AJ) if she doesn't help govern, but if they don't find her friends within six years, she would get executed in front of all of Equestria. The faith of her, her friends and Equestria are in her hooves.
