Twilight is summoned by Celestia to discuss both their futures. Will she be able to make a decision that will not only change her life, but possibly affect the fate of all of Equestria? And will she be able to handle the truth when she discovers the true cost of Celestia's and Luna's existence, and how they tie in with the elements of harmony?

A little side story I've had on my mind for quite a while, I hope those who read it find it entertaining. It's not to dark or sad, but enough that I felt the tags were necessary.
