Twilight Sparkle has been hiding a secret. A dark secret. Once she turned into a princess, she has wanted nothing but to rule with all the riches of the land. But when a dark villain from the very, very late past has spawned in Equestria once more, the Elements of Harmony can handle it, right? Yet when the antagonist gives Twilight two choices; Sacrifice Celestia and have all riches, or face the villain alone without her Element or the other Elements, what will she do? Will she rise above herself and defeat the villainous beast once and for all? Or will her corruption of yearning for power and wealth overcome her good deeds, and destroy herself and the Elements of Harmony, plunging the world into chaos forever?
