When Starlight Glimmer came back for her revenge, Twilight stopped her. The mad unicorn had attempted to change the course of history itself, and over, and over again, she had done so, sending Twilight into alternative timelines. Ugly, dark timelines.

She stopped Starlight in the end, pushed to her limit, but she had saved her home, her friends, and even Starlight herself.

But those times... Can anything say they aren't real? That the ponies who live there are not alive?

That those times cannot be just as true as the one Twilight lives within?

Dark times, ugly times. And Twilight will cure them, save them. Right their course through any method she can.

Whether she wants to or not.
