This isn't where I belong. I left all this behind years ago, moved on with my life. But a mare from my past brought me back, and now she won't let me go. So I'm stuck here, trying to make the best of it with ponies that don't understand me, don't even like me. But when something moves in the darkness, and when things go wrong in the cold, dead night, they'll turn to me to try to set things right.

Why? Because once a police pony, always a police pony.

There is now a side-story: A Hard Day's Nightmare Night

The world has been dying for as long as the Enchantress can remember, reduced to little more than a desolate expanse of sand. And yet, she keeps walking, for she knows she is the last hope of the world.

When mares from extremely different worlds arrive in her desert, the Enchantress is forced to reexamine everything she thought to be true. There will be stories of monsters, books, ghosts, gods, stars, machines, and ponies who have not lived most of their life in a world approaching the end. They must come to terms with their vastly different experiences in a tangle of alternate worlds no one is prepared for.

The multiverse is a big place, and this small corner of existence has just received some unwanted attention.

Effective communication is important in any friendship.

Unfortunately for Twilight, Tempest Shadow and Pharynx communicate almost exclusively in overwhelming force.

This story is a sequel to The Celestia Code

When the monsters created by the dark crystal engine escape their prison, it's up to Princess Twilight Sparkle to deal with them. She gets help and advice from Princess Luna, but things don't go as planned. In fact, when a pony who relies on logic and rationality tries to navigate the stormy seas of emotional entanglement while simultaneously saving Equestria from a horde of evil creatures intent on destroying everything they encounter, nothing goes as planned.

WARNING: Major spoilers in the comments.

Book 2 of the Alicorn Adventure series.

Goodreads Page
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!

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

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.

Narrowly avoiding imprisonment due to the intervention of the Princess of Friendship, Tempest Shadow reflects and prepares for the new role she has been given in Twilight Sparkle's kingdom.

(Update: 11/5/2017 - Major shout-out to Rock-Mint-Swirl who was incredibly nice enough to do a fanart for this story, which you can see right here. It contains story spoilers so please read the fanfic first though.)

The Cutie Mark Crusaders have dealt with all kinds of ponies having trouble finding their true calling in life, but none can compare to the special request they receive from Princess Twilight Sparkle herself, or the shock they receive on discovering who it is: Fizzlepop Berrytwist, possibly the most hated and feared pony in generations. Can a pony who's spent most of her life rejecting her true calling possibly find it now? Can the Cutie Mark Crusaders help a pony who almost everypony else in Equestria has rejected?

Movie Spoilers.

Princess Luna, Sunset Shimmer, and the Great and Powerful Trixie meet in a bar every Friday for drinks and to chat.

This is what they chat about.

An episodic story updated whenever I think of anything new. Will probably never be marked "Complete".

Rated Teen and Sex for risque conversations. No actual sex. Has a little Sunlight shipping; as usual, I cannot help it.

Many thanks to FanOfMostEverything for being kind enough to preread the first three five all the chapters for me!

This story is a sequel to Unfriendly Competition

That's probably the only thing they can agree on...
