Strongly Recommended Stories:
The Brightest and the Best by Pineta - The events in this story are considered to be completely canon to this timeline and explain Twilight's entrance exam to Celestia's School for Gifted Unicorns. I cannot recommend this story enough.
MLP Annual 2013 - "The Fall of Sunset Shimmer" - As above, the 8-page short comic in the beginning of the Annual is also considered to be canon, though with some major variations.

Version 3.0 Edit: Extensive grammatical and mechanics changes. Adjustment to timeline of Sunset's second mirror experience.

Annoyed that the nobles keep taking up all of princess Celestia's time filly Twilight vents the only way she knows how. By writing an essay! However she wrote this essay on the blank bottom of the scroll containing the speech Princess Celestia was to read to her little ponies. And once the speech ends, Celestia doesn't stop. Much to the horror of some of the nobles in the crowd.

This story now has a Youtube reading.

Chrysalis is miserable. The swarm is scattered, her hopes are dashed by defeat, and her royal rump is freezing off in these mountains.

The only thing that could make this worse is a baby drone who wants a bedtime story.

Part of the Hellpiercer 'verse, but knowledge of that story is not required.

We must be stopped.

Princess Celestia, tired of the constant pressure that ruling a nation puts on her, decides to take a day off and let Luna take her responsibilities for a day, something the younger alicorn is more than happy to do. She disguises herself as a pink maned pegasus pony named Sunny Skies and decides to go walking around Canterlot without any supervision. Unfortunately for her, not all parts of Canterlot are as safe as the palace, and she finds herself at the wrong end of a gang of muggers, who decide to kidnap her for a ransom when they see how much money she has on her.

Luna freaks out.

Celestia thinks it's hilarious.
