As Twilight and Spike move into the castle, he, Applebloom, and Sweetie Belle decide to look around the only part of the castle no pony's checked out yet. The basement. Only, when they find a door that doesn't match the rest of the castle, they find a way inside and find the room to be look even more out of the ordinary.

As they try to figure out what the room behind the door's about, it begins to alter their own lives. Now, everypony (and dragon) has a job to do. Will it pay off?

The story takes place after the Season 4 finale. Depending on how season 5 starts, the story may or may not follow along with it.

Also, thank you to my editor/proofreader Malefactory for all the help he's done from chapter 2 onward.
