Everypony all over Equestria wakes up to a black day, no sun. And the moon isn't even there. Panic quickly rises and a gathering at Canterlot is issued by Celestia's sister, Luna. The panic worsens when Luna claims that her sister is still physically alive, but has no soul. Many questions were asked, including if it were a prank that Celestia and her sister were pulling over the entire province of Equestria, but it is no joke.

Celestia wakes up, though, not in the real world. Where she is, is darker than night. After getting used to the darkness, she sees that which would only reside in death. But she was wrong. She is given two doors. One black, deep and feared, and the other white, comforting and beautiful.

She refuses both till she comes to a decision. And what a mistake she has chosen. The doors both fade to nothing and she is plunged into a world of evil and danger. Will she make it back to the living world, be trapped in between the two, or pass on to the afterlife, leaving Luna to manage the world herself?
