This story is a sequel to The Cadenza Prophecies

Princess Flurry Heart inherited her mother's beauty and grace as well as her father's strength and bravery. The Empire couldn't hope for a better or more suitable heir to the Crystal Throne. Everypony in Equestria admires her and thinks she will be an ideal ruler.

They're wrong.

Young Flurry Heart has no interest at all in being a prim and proper princess, and would much rather have wild and dangerous adventures like her Aunt Twilight.

Book 5 of the Alicorn Adventure series.

This story is a sequel to The Luna Cypher

Twilight sets out to learn more of the ways of the world, and soon decides that the whole planet is disorganized, insanely dangerous, and desperately needs to be fixed. And she's just the mare to do it... with a little help from her friends.

Also, there are sky-pirates!

Book 3 of the Alicorn Adventure series.

A few extra, slice-o-life chapters are here: On the Rocks

100% Approved by Twilight's Library!

The Badass Twilight tag applies more than ever, but please note the new tags.

This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

The sequel is here: The Twilight Enigma

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!

Princess Twilight Sparkle discovers a centuries-old mystery hidden in the Royal Archives. Her investigation leads through layer after layer of deception and misdirection, setting her hooves on a path that seems to be leading to a mysterious secret. Along the way, she learns that some friendships can be very, very strange.

Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.

Once upon a time, Silver Spoon's life made sense. She had the right friends, the right house, and the right school for a young lady coming up in the world. Once upon a time, Silver Spoon lived amongst proud towers in a vibrant, bustling city that never slept.

Now she lives in Ponyville. Not so terrible once one gets used to it. Silver's learned to appreciate some ponies, harbor grudges for others, and tolerate the rest. But sometimes, she wonders if one pony in particular is as popular as she thought.

Chinese translation by hehelover

Garble has won the Gauntlet of Fire and taken the Bloodstone Scepter. Upon hearing of this, Celestia, determined to stop the bloodthirsty Dragon Lord in his tracks, challenges him to a one-on-one duel for the fate of Equestria and the Dragonlands. An immortal alicorn capable of moving the sun with millennia of experience under her belt versus a teenaged dragon with no experience at all.

Garble accepts.

Stupider things have probably happened, but it's hard to say how.

Cover art is taken from this comic by Niban-Destikim.

Twilight Sparkle - magus, heroine and Princess - has learned of worlds overlapping Ungulatia in space and time. Though this has been a well known phenomenon, safely traveling to these other worlds has always eluded pony mages. But now - after years of research and careful experiments - she prepares herself for the most audacious of all experiments: stepping hoof on the surface of an alien world and returning safely! What wonders will she find once she walks through her magic portal?

This assumes that Equestria Girls never happened.

For years, Twilight Sparkle and Queen Chrysalis have been at each other's throats. Both have experienced victory over the other, and both have experienced defeat. Out of all the creatures in Equestria, none despise each other the way the pony Princess and changeling Queen do. They seemed destined to remain locked in battle forever, or at least until one is finally dead at the hooves of the other. The cruel insults, the vicious loathing, and the powerful spells that have passed back and forth between them at each meeting have become the stuff of legend.

Imagine Twilight's surprise when she finds out changelings consider this dating.

And now they're married.

Some beautiful fanart of the end of chapter three was done by Dmann892; you can see it here.

More awesome fanart, this time from chapter one.

Now with a TvTropes page (obligatory TvTropes warning goes here).

If you want a Russian translation, you can find it here.

There is now a reading of the story on Youtube, which starts here.

Just because the two sisters have led Equestria through thousands of years of peace doesn't mean there aren't those who think they can do better.

With a powerful artifact on their side, a group of rebels has sealed Celestia in her palace and stripped her of the majority of her powers. As the last of her guards fall, she hears the pounding on the throne room doors and knows the end is coming soon...

**Featured on the front page on 8/12/15; both surprising and flattering seeing as how this is the first thing of substantial length I've posted here. Thanks all!

**Now with a dramatic reading!

Time after time, through chaos and through wars, Princess Celestia prevailed.

Of all the terrible forces she could have fallen to, Flim Flam Industry was the last one anypony had expected.

With thanks to gardrek for editing (3-6) and PinkieDP, Ice Star, and Odd_Sarge for prereading help.
