This story is a sequel to Princess Celestia: A Brief History

  When Celestia first laid eyes on Twilight Sparkle, she knew she’d seen her somewhere before. Though she’d managed to hide this from both Sunset and Twilight, after they departed for the evening, Celestia needed to be sure.
  With her trusted aide Raven at her side and a dangerous threat on the horizon, Celestia heads to the offices of the Equestrian Secret Service to investigate her suspicions.
  Because if she’s right, the possibility of eternal night is the least of Equestria’s concerns.

This story is a sequel to The Application of Unified Harmony Magics

  After the incredibly awkward reunion last night, Sunset is less than eager about her promise to introduce Twilight Sparkle to Princess Celestia. Maybe it would help if Twilight could go more than five minutes without a panic-driven ramble.
  Despite her doubts, Sunset decides to do her best. But between a bowl of ice water, Philomena’s antics and Celestia’s sly smile, Sunset knows this isn’t going to be easy.
  Still, Twilight probably could have handled it better.

Special Thanks
Fahrenheit - For wonderful advice on creating an epic and entertaining synopsis!

After saving Camp Everfree, Sunset Shimmer just wants to kick and celebrate like any typical teenaged girl. Or at least as typical as one can be when you now possess magic powers that let you see into the hearts and minds of others.

But memories are a fickle thing, and when Sunset Shimmer runs into her ex-boyfriend, she soon discovers that even a memory can be deceptive.

Special thanks to SolidFire for his editing work.

This story is a sequel to Sunsplit

"...okay, ow. My head hurts. I wonder how long I've been--oh, who are you?"

Starlight Glimmer is about to embark on a few little friendship lessons. Five to be exact. However she’s still a little murky on how to get all her friends to cooperate so things go as quickly and efficiently as possible. Luckily A surprise visit from another friend might solve Starlight’s problem.

An alternative take on Every Little Thing She Does and inspired by a conversation with Tired Old Man.

She really, really is.

And Twilight has to deal with it.

Sunset has reached the final page in her journal to Twilight. With no idea what to write on it, she has to think about living life without the guidance that she's relied on for so long, and possibly without one of her best friends.

This story is a sequel to Bards of the Badlands

  Sunset hates dealing with chaos surges, no matter how amusing Moon Dancer finds them. After a particularly annoying surge while tutoring Moon Dancer in her advanced telekinetic studies, Sunset takes refuge in the teacher’s lounge. Though she was only looking for a cup of scalding hot tea, Sunset finds a pony walking down the same path she once walked, giving her an opportunity she’s never had before…
  To help somepony not out of guilt, but just because it’s the right thing to do.

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.
