This story is a sequel to Sunset Shimmer Lends Pinkie Pie the Wrong Thumb Drive

Sunset Shimmer visits the Castle of Friendship, and inadvertently discovers something that Twilight would normally keep hidden under her bed... except that since this is a pony princess we're talking about, it's obviously nothing remotely resembling normal.

Rated Teen and Sex for discussions of pornography and self-love.

The last day of school has all but come and gone. Rainbow and the others have left to prepare the holidays with their families, leaving Sunset all by herself. Ready to spend another Christmas alone, Sunset exits CHS only to be greeted by a familiar face. Someone that comes bearing a gift Sunset never thought she'd receive.

In fact, it might just be the most important gift of Sunset's life.

Edit (26/12/2016): In my haste to get this ready by Christmas, I neglected to mention that Warming A Hearth in Another World by Flutterpriest was one of the inspirations behind this tale. I always try to give credits where they're due but this one slipped through the cracks, sorry!

This story is a sequel to Luna's Protégé

'Or through Midnight's Radiance, the Sun extracts obedience.'

Things are looking up for Sunset Shimmer.
She's been a proud student of Princess Luna for over twelve years, has the best friends a pony could ask for, a young dragon she cares for dearly, and ambitions on the cusp of completion.
And even better, it looks like everypony will be spending the Winter Solstice together! Assuming of course, that Celestia's return doesn't end up ruining everything...

Distant sequel to Luna's Protégé
Thanks to Cloureed again for the cover!
Set in the Trio-verse.

This story is a sequel to Triggered

Sunburst might be a grown stallion, but that doesn't keep an overprotective sister like Sunset Shimmer from smacking a filly.

While tearfully repairing the wall she destroyed, Sunset Shimmer can't help but reflect on what a horrible person she is. Convinced she'll never be forgiven by her peers, and unsure if she's even worthy of it, she's visited in the night by one of the last people she expected.

Sunset Shimmer visits Equestria and spends some time taking care of animals with Fluttershy and Rainbow Dash.

Rainbow Dash is apparently not good with certain animals.

Sunset discovers very quickly that what you learn from the human world cannot be unlearned, ever.

Rated Teen and Sex for a pile of juvenile innuendo, though technically no bad language. Only technically.

Rarity was sure she'd failed Prim Hemline in creating a suitable window display for Carousel Boutique—only to find the most beautiful of artworks in those same windows the next morning. Even more surprising: Sunset had painted and arranged them.

A most wonderful turn of events, as far as Rarity was concerned—with just one problem.

How did Sunset manage to paint the window displays of a closed boutique overnight?

Part of the Montage Cinematic Universe.

While lounging around Twilight's castle and airing some friendship-related grievances, Discord stumbles across a magic book containing letters from an inter-dimensional pen pal. As it just so happens, this pen pal also had sinister designs for Equestria, but was quashed by the Elements of Harmony. What's more, she's made amends since that day, and she's now Twilight's friendship student. Eager to bond with someone who can relate to him on a personal level and grow into a better draconequus, Discord packs his bags and heads off to the human world with Twilight's semi-blessing. His mission: Befriend Sunset Shimmer.

However, his plan has a bit of a snag. See, Sunset hasn't been keeping up with Equestrian events, and she never got the memo about Discord turning over a new leaf. As such, she believes that his sudden appearance doesn't bode well for Equestria, Canterlot High, or herself. Not only this, but the Sirens are privy to Discord's return as well, and they see this as a golden opportunity to bounce back from their own recent defeat. Well, Adagio does, anyway. Sonata doesn't want to live in a world that makes no sense, and Aria would rather maintain what little dignity she has left by not getting involved (or so she claims).

So while Discord is trying to earn Sunset's trust and show her what a good friend he is now, Adagio is trying to get in on an evil scheme that doesn't exist. And while that is going on, Sonata is appealing to the Rainbooms behind Adagio's back, hoping that they'll make Discord go away. With so much miscommunication thrown into the mix, you just know that hijinks are inevitable. Good thing Aria made popcorn.

Sunset Shimmer: Ex-Queen bee of CHS. Ex-She-deamon. Ex-villain. Overall bad-ass.

However, as the hair 5 are learning, Sunset isn't all she may seem to be. This confident girl may just have a secret or two that she doesn't want out.

"Sunset, you weren't the first unearthly threat to come to this world, and you won't be the last. If we seem calm in the face of strange events, it's not because we're oblivious or indifferent to them. It's because they're not strange to us. The Fall Formal may have been the most important night of your life, but to us... it was Thursday."
