The Celestial Era has lasted for hundreds of blissful, peaceful years. The Glorious Sun rules all, sees all, knows all. The citizens of Equestria are happy, perfect specimens- because they have no other choice, nor would they want it to be otherwise. A young mare, Twilight Sparkle, finds a small, unexpected, inquisitive spark leading her to ask questions. Difficult questions. Questions to which she will not like the answers.

For The Sun Rises, but The Sun Never Sets.
