Overwhelmed by her new duties as a princess, a newly-crowned Twilight Sparkle seeks solace within the quiet confines of Canterlot Castle's royal archives, where she discovers a book she'd never seen before. Within its pages was a story about both Princess Celestia and Starswirl the Bearded, as well as a mare that Twilight had never heard of.

Details of their lives, their history, and their relationships puzzle, intrigue, and even worry Twilight. The more she read, the more curious she became and the more questions that arose. But there was only one question to which she truly sought the answer:

Who was Sunset Shimmer?

This story is a sequel to The Adventures of Schadenfreude

Schadenfreude has nothing to do. He's bored. Bluey's gone for a few days, his friends are all busy, and, oh, Ponyville is on lockdown thanks to the apocalypse.

Really he just wants some froyo.

The foggy feeling like you're wandering through a dream, disconnected from the world around you. Sunset Shimmer experiences that every day. Ponies struggle to remember her, she suffers from random bouts of exhaustion, and at eighteen, she still has no cutie mark.

Despite the claims her mother makes, Sunset knows she is broken in some way. It isn't until her nineteenth birthday that she discovers why.

When her perception of herself and the world around her shatters, Equestria will face the consequences of the villain... or the hero, it was never supposed to have.

This story is a sequel to How Not To Use Your Royal Prerogative

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.

It was just like any other night. The moon had been up for hours and the ponies rested peacefully in their beds. Celestia, on this normal night, decides to take a stroll around the quiet palace.

This seemingly routine walk changes everything for her as she finds one young unicorn thief trying to rob her.

And this thief, harnessing magical powers quite rare to normal unicorns, catches Celestia's attention.

Pinkie Pie is known as the party planner of Ponyville, the happiest mare you will find, one that's always willing to help or cheer you up no matter what. However, these past days, the mare seems to have been lacking some of that enthusiasm.

Will her friends discover what's causing it before it's too late?

This story is a sequel to The Adventures of Schadenfreude

Sunset Shimmer doesn't ask for much. She has great friends, a good life, good grades, and has even made peace with her mentor, Princess Celestia. Everything else, she works. for, and she's happy to do it. Including the forgiveness of her fellow students.

Deciding that the best way to make up for her mistakes with the student body, especially those of the last Fall Formal, is to take this year's Formal into her own hands, she applies for the position as Chairman of the Planning Committee. Unfortunately, it seems that some of the teachers haven't forgiven her, either. So they decide that, if she truly wishes to make up for her mistakes, she must do so by working with a member of the student council, it's Sergeant at Arms, as co-Chairman.

Which is me. Pleasure to meet you. I'm Schadenfreude.

And this is how the world ends.
