Twilight Sparkle is invited to a party that Pinkie Pie is throwing. In fact, everyone is! It's a huge blowout and everyone in Equestria is invited. Twilight is dancing and smiling, greeting all her favorite foals, having one of the best nights of her life, but an unexpected cataclysmic disaster befalls the ponies. Spike, Rarity, and Pinkie Pie are nowhere to be found. In her quest for the truth and unearthing the mystery of the big Showroom Catastrophe, Twilight comes to realize that she can trust no one. She comes to realize that horrible things can happen to anyone at any time and it doesn't matter if you take all the right precautions, it doesn't matter if you are diligent about knowing the facts, it doesn't matter if you're careful, it doesn't matter if you're powerful. This world will take from you without mercy and will destroy everything. It doesn't matter if you meticulously protect yourself and everyone around you. You can never be immune to chance, you can't control what happens outside of yourself no matter how hard you try. All her life, she's fought for control. She has been obsessed with directing her entire existence, but she knows now that all of it was for nothing. Her whole identity thrown recklessly into a shredder and decimated before her very eyes. All she wants is control.

All she wants is control. But... she can't control what happens. She can't control other ponies, and she can't control the horrific consequences of other ponies' actions in her life. She can only control herself. She can only control herself.
