Sunset Shimmer is a young mare who strives for power and doesn't care about anyone but herself.
Twilight Sparkle is a little filly with more scars than she lets on.
Now both of them have to make do, stuck in a world where their greatest talents are little more than a pretty mark on their clothes.

Cover art commissioned from GPizano, who draws a pretty awesome Sunset Shimmer.

After one of their worse arguments, Princess Rarity starts to avoid Twilight, spending more and more time in her room. That wouldn't be quite as much of a problem, if not for Twilight's duty to protect the Princess at all times.

Written as my second entry in Monochromatic's Raritwi contest and set in her Bodyguard AU, which in turn is based on Earthsong9405's AU that I've never actually read.

Twilight knows that Rarity is a hopeless romantic, experienced through countless romance novels.
Twilight knows that Rarity has had some bad experiences with romance and courtship.
Twilight knows that Rarity still dreams of somepony to properly sweep her off her hooves.
Twilight has no idea how Rarity keeps missing the hints she keeps dropping.

Top of the Feature Box on 05/05/17 and then for 72 hours straight: A huge thanks to everyone who liked or commented on this story.

I don’t know why I’m writing this. I don’t know if anypony will ever read it, or if there is anypony left who could ever read it. Some might see it as a way to keep my sanity in this place, but that implies that I have any sanity left to lose. I’m not so sure about that right now. I’m not sure about anything anymore.

My name is Sunset Shimmer, and I am the Princess of Equestria.

Cover art put together by Amber Spark, who writes a way better Sunset Shimmer AU than me. Now go read her Wavelength series.

Written for FOME's "Imposing Sovereigns" Contest.

Twilight Sparkle is not in a good place. Shunned and abandoned by her friends, her mentor and even her family for a thoughtless outburst at the wedding rehearsal. But she still has friends in Canterlot, even if she forgot about them.

Oh yeah, and somepony should probably do something about that whole changeling issue.

Written under the prompt "Warrior Twilight" for FOME's Imposing Sovereigns Contest.

Wealth, Fame, Power.
The pony who acquired all that was Gold Clover, the queen of pirates. With her last words she said:
"You want my treasure? Go and get it! I left it all in that place."
Ever since then, pirates from all over the world have been travelling to the Grand Line to look for the legendary treasure, the One Piece. This is the story of one of them, Pinkamena D. Pie, better known as "Straw Hat Pinkie".

Not just a retelling of One Piece. With all those new characters, the story won't be nearly the same as the manga. As such, knowing the manga is not required for enjoying the story.

Not recommended to be read on e-book, due to the loss of formatting when it's downloaded over the site.

Sunset Shimmer has learned a lot about friendship. Probably almost as much as her mentor Twilight Sparkle.
But it takes a trip through the mirror to reveal just how far she has gotten in her studies, and how far she has really followed her mentor on the road of friendship.

Starlight Glimmer has successfully trapped and equalized the former Bearers of the Elements of Harmony.
Starlight Glimmer has successfully trapped and equalized Princess Twilight and Princess Celestia.
Now everypony will experience true equality. Nothing can stand in the way of her triumph.

...right?

If that isn't the start of a joke, it sure sounds like one. And like any good joke, it will probably include a lot of eye rolling and several special love touches knocks on the head from Octavia.
What else can a pony do than sit back and try to enjoy the show.
