In the aftermath of a Canterlot Wedding Invasion, Twilight decides to leave on her own. Far away from feeling abandon of betrayal, trust, and friendship. Until she heard some kind of whispers or voices calling to her from the Crystal Cave she recently escaped with Cadence. Finally arriving at the cave entrance, Twilight walks inside it and sees a glowing tainted light. Not knowing the danger, Twilight tries walking closer to it until something inside the tainted light grabs a hold of her and drags her in. Twilight later wakes up upon seeing a burned town and felt strange that her whole body transformed into a human. Then something told her to look behind her and sees a lone tall figure on the back of his horse looking down at her. What'll happen when Twilight faces the King of Darkness and will Equestria ever be safe without her?
