On a day of remembrance, a new threat arises, shedding light on old mysteries.

This follows Two Pair by about 700 years, but is not a very similar story, and reading Two Pair is not necessary to understand Sparkle Day.

This story is a sequel to The Celestia Code

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!

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 The Fruits of Their Labors

Rarity always believed that she knew exactly who she was, what she wanted, and exactly how she would obtain it. Then she fell for somepony wholly unexpected: Applejack. When unhappy tidings call Rarity to the frozen North to spend the Hearth's Warming holiday with her relatives, Applejack accompanies her into the family fray.

The ponies arrive in Whinnyapolis at a time of endings, and find that relationships can be fragile things, vulnerable to the cold. Rarity will search her past for the key to her future, but the old house at Maple Cove may not hold all the answers she needs. Perhaps, though, two ponies will learn that there really is no place like home for the holidays.

This story is a sequel to The Dresden Fillies: False Masks

It's been a while since the girls have seen their good friend Harry Dresden. Discord escaped, Luna attended her first Nightmare Night, the Royal Wedding was crashed by hordes of changelings, and Pinkie Pie threw a statistically improbable number of parties. They tried inviting Dresden, but between his new job and new apprentice, he always claimed to be too busy. The solution was obvious; if he couldn't come to his friends, they needed to go visit him. Besides, they say Earth is lovely this time of year. What could go wrong?

When the Royal Wedding scatters defeated changelings all over Equestria, a member of the hive winds up being captured in Ponyville, tied up, stunned, repeatedly shot by a cannon, and held against his will.

The truly frightening part is he’s starting to like it.

This story is listed as comedy⁽*⁾ because the author has an odd sense of humor. No changelings were harmed⁽¹⁾ during the production of this story, despite what the newspapers printed or the ongoing lawsuit from the ESPCA⁽²⁾. The management would like to remind all readers to spay and neuter your pets. Unless your pet is a changeling, in which case…

(*) Dark humor, to be exact. If you are someone who finds pleasure in the misfortune of others, enjoys watching the occasional inept chainsaw juggler or cheers during a NASCAR crash, welcome home. Also, get help.

(1) Excluding blunt trauma, thermal impingement, chemical exposure, radiation, thaumaturgic infusions, and confetti ingestion. All characters represented, including changelings, are the exclusive property of Hasbro, no matter what they may shout at you from between the bars of their cell. Any violence or pain inflicted on the changeling in this story was simulated on a stunt changeling with special effects and mirrors. Except for the cannon. There is no truth to the rumor that Queen Chrysalis provided the stunt changelings from a supply of disobedient changelings in her dungeon⁽³⁾.

(2) Equestrian Society for the Prevention of Cruelty to Arthropods

(3) The Changeling Kingdom does not have dungeons. They have Call Centers. It explains a lot, actually.

Additional Note: This story is tagged Sex because it has the occasional reference to… well, sex. There are no explicit references, but there are things.

A holiday tale in which Cheerilee learns the true meaning of the word "wassail"; Granny Smith fails to learn the true meaning of the word "polymath"; and somehow, amidst it all, three flowers finally begin to put down roots. Happy Twelfth Night, everypony.

Now with a Spanish translation by Spaniard Kiwi!

Princess. Alicorn. The pillar of all ponykind, against which so many ponies often judged themselves. Celestia hates having to constantly be these things, and it's past time for a break. Luna will watch over Equestria while her sister is gone, but taking a break from your duties and taking a break from how the world sees you are two very different matters. Enter Prominence, a quiet pony who nopony really pays much mind to. Perhaps because she doesn't exist.

Aided by this disguise, Celestia will find her peace and relaxation in the home of one of the few ponies who know Prominence's true identity: Princess Twilight Sparkle. But when Twilight begins to see Celestia as a pony, and not a princess, can she deal with the feelings that arise? And are the feelings for Celestia, or for a pony she knows is not actually real?

EDIT: I've been featured, July 19th, 2014. I have no words to express how terrified and humbled and terrified and proud and happy and terrified this makes me.

Mysterious portals to a “First World” are appearing all around Equestria. Even worse, there are unknown creatures coming through! When it’s discovered that these creatures are immune to unicorn spells, Twilight comes up with a bold idea to harness earth pony magic to combat the menace. Applejack must take the first steps on a new path she never expected, which just might be the biggest challenge she’s faced yet.

This is pretty much my first work of fiction, so I greatly appreciate any and all feedback. Let me know what you think!

Might contain some incidental Dungeons & Dragons crossover elements, but not enough to warrant the tag, I think.
Rated Teen for mild violence and language.
