Following Twilight Sparkle's near-permanent death trying to save Princess Celestia, Twilight has created a Nopony which is shortly inducted into Vanitas' New Organizaton XIII, alongside a majestic other Nopony that looks vaguely familiar and Discord, who is trying to escape his troubled past. As Twilight's Nopony works for the Organization and hangs out with her new friends, she learns more of her origins and about what the Organization really does, questions which may cause her to leave her friends and the Organization forever.
This takes place following the events of Rebirth by Awakening, and has the main character having several memories of Twilight's past adventures and contains hints to the season three finale.
