This story is a sequel to Freeport Venture: More Equal than Others

Sunset Shimmer had grand ambitions upon becoming Freeport's only magus, most importantly helping out the citizens of Freeport itself. When she hears of an outlying farming community in danger from a horde of undead, she knows she has to help them. Even if they can't pay her fees, it's the right thing to do.

However, this new challenge might be too much for her to handle. These zombies are unlike anything she's ever seen, and an old enemy is mixed up in the middle of all of this. Sunset has no idea what dark secrets the undead horde hides, or the danger posed by the necromancer behind it.

As the eternal regent of Equestria, Princess Celestia's knowledge of magic is without equal. Over her long life, only a few gifted ponies who had a great destiny before them have had the honor of learning at her side. Sunset Shimmer was one such pony: one of Celestia’s best and most promising students. As she learned at Celestia’s hooves, their bond strengthened until they became far more than student and teacher to one another.

Sometimes those closest to us are the ones who can hurt us the most.

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.

The wheel of time turns, as destiny and history clash together.

Fifty years into the future, Sunset Shimmer is Princess Twilight Sparkle's most faithful student. She is smart and eager, but doesn't always think things through. Her life had been perfect, right up to the End of the World.

With a ruined future, Sunset travels into the past to alter the course of history. With only her mentor's cryptic word to go on, Sunset and the Elements of Harmony must solve the riddle of the Dark Regalia and stop the mysterious Vesper Radiance from rising to power. But the further Sunset goes, the more she feels like she's been through it all before.

Is destiny set in stone, or can Sunset shape her own future? Only time will tell.

The Sunset of Tropes page!

Princess Rarity had everything planned for her beloved bodyguard's birthday. It would start with a lovely trip to Trottingham, continue into an entire day in Equestria's oldest library, and culminate into a wonderfully romantic moment in the Ethereal Gardens. It would be Twilight's best birthday yet!

...If only things actually went according to plan.

Part of the Bodyguard!AU Series, based on Earthsong9405's AU where Twilight is the bodyguard to a "Princess/Queen Rarity". Prior knowledge of the AU is not necessary to read the story.

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.

Principal Celestia has accidentally fallen through the mirror into Equestria, and it may be a bit before she can go home. Until then, she has to learn to cope with a strange world, in a strange body.

At the same time, Twilight has to figure out how she can help her new guest while keeping Equestria from freaking out over the presence of a second Celestia, and Sunset Shimmer has to figure out how she is going to make amends with those she had left behind in Equestria, while keeping an eye on her Principal.

Disclaimer: Since I wrote this description ages ago before I even knew the plot, the story is mostly pure comedy in the beginning, with eventual Sunlight and Chryslestia shipping!

This story is a sequel to You're NOT a Lesbian, Rainbow Dash!

Displeased at the chaos that their lack of basic sexual education has caused, Princess Celestia teleports Spike, Rainbow Dash, and Twilight Sparkle to her throne room to have a few words.

Unfortunately, Twilight manages to derail the conversation with something she sees as being of far greater importance.

Warning! Contains suggestive topic references of sexual nature.
