Most days, Princess Celestia loves her job as the ruler of Equestria. Other days, it really grates on her nerves. Between frustrating council meetings, bothersome appointments with greedy subjects, and paperwork addressing countless issues from all across the country, Celestia deals with more than her share of stress in the span of a day. After an unannounced visit from Discord, Celestia suggests an idea for how she can not only get away from her job for an afternoon, but leave behind the stress and anxiety that it comes with, completely forgetting that it even exists.
She wants to be a dog.
While such a thing might not even make sense to the reformed master of chaos, Discord grants Celestia's request. The idea may seem fun to him at first, but before the day is over, Discord may learn that being a pet owner comes with its own set of headaches, especially when that pet is the princess of the sun.

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!

Cloud Kicker might just have the wildest life of any pony in Equestria. Marvel at the insanity that is her life, and laugh at the suffering of her poor beleaguered best friend, Blossomforth. And maybe, just maybe, there's more to her than just the lovable sex maniac everypony thinks she is.

This is a semi-sequel to "The Incredibly Dense Mind of Rainbow Dash." Not really a proper sequel, since it's focused on Cloud Kicker and Blossomforth instead of Rainbow and Pinkie, but it's in the same continuity. So I guess that makes it a follow-up-side-quel story. Or something. You don't need to have read "The Incredibly Dense Mind of Rainbow Dash" to read or enjoy this, but you ought to read it anyway, just because.

The central story of the Winningverse.

We got a tag for Cloud Kicker, but Blossomforth still deserves one too.

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.

WARNING: Major spoilers in the comments. Takes place several months after the end of season four. (Not a Da Vinci Code crossover, BTW!)

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.

This story is a sequel to Into The Depths

The horrors of the catacombs have turned to distant memories for Celestia, Twilight, and Luna. Discord’s change of heart and Twilight’s coronation have helped to ease and erase the mental scars from that harrowing night. The three princesses can even smile and laugh as Nightmare Night moves into full swing.

Yet, it should never be forgotten that those who have been touched by Tirek are forever within his grasp.

Button Stitch is an excessively regular mare with excessively regular habits, but something strange has begun to happen to her in the wake of Discord's rampage. Can Rarity and the rest of the girls get to the bottom of the strange manifestations of nonsense that have been plaguing Ponyville?

Continued in Screwball Mio Amoré

This story is a sequel to Pipsqueak's Day Off

Lickety Split has a big day tomorrow, and all he wants is to relax and prepare.

His friends—Dinky Doo, Pipsqueak, Ruby Pinch and Tootsie Flute—have other plans. They feel he should be celebrating. With copious amounts of alcohol, clover, and loud music.

At least his boyfriend, Rumble, is here to help...

Prepare yourselves for the long-awaited sequel to Pipsqueak's Day Off, a terrifying tale of hubris, indulgence, and weird science!

When Rarity is overwhelmed with making designs for an agriculture exhibition, she turns to Applejack for advice. But when she gives Applejack a hair style treatment in return, the apple farmer lets her accent slip from southern drawl to sophisticated Manehattenite. The result? More fancy parties than you can shake a candy apple at!

The Dreamworld is peaceful tonight.

Nightmares are few and far between. The psychic predators that inhabit it are keeping their distance. Everything is running smoothly...and it's boring Luna to tears.

While searching for something to do, Luna comes across a dream like none she's ever encountered. With nothing better to do, she enters it...
