AU from "The Return of Harmony."

Discord did it. He broke the ponies that embodied the Elements of Harmony. He stopped Celestia and Luna from using them. and now he rules Equestria. However, there's one he didn't break. One that's fighting the clock for a way to fix the chaos he's wrought. But without the magic of friendship, can she do it? Can Twilight fix her mistakes and take down Discord? Or will she break, too, ending the last hope Equestria had?

Based off of Aviator's "Friendship," "One Last Letter," "Open Your Eyes," and "Heroes," linking them together to make a narrative, though they don't really have anything to do with each other.
