Rarity awakens to discover time has stopped for everyone but her and her love, Twilight Sparkle. And also Trixie. And a growing number of other ponies. And strawberries.
An exquisite corpse is a form of collaborative art where each participant only knows about part of the whole work, and must complete their part with limited context. In this case, each writer only had access to the previous chapter, resulting in the story getting confused, yet still moving forward undeterred. The exception is me having full context when helping out the others.
Participating writers were me, The Red Parade, Gearcrow, WiseLlama, Cynewulf, Ruby, trAce, Lingo, Lopunny, Undome Tinwe, and Nonchalant.
