After being reformed during the events of The Cutie Re-Mark, Starlight Glimmer was secretly called upon by Princess Celestia herself for an important task. Certain individuals from Our Town had adopted Starlight's philosophy and left to create a larger Equalist Party with nefarious plans for Equestria. So, for much longer than she desires, Starlight must now live as a member of the ruthless Equalist Party at the command of Princess Celestia. It is a long pair of even black roads through the darkness, on which Starlight must walk alone. Now completely spurned, scorned, and hated by Twilight Sparkle and her friends, Starlight must keep up her Equalist persona as she secretly infiltrates and foils the plans of the extreme Left-Wing Totilitarian Equalist Party.
