Twilight crosses the mirror portal to pursue Sunset Shimmer after the theft of the Element of Magic. She finds herself in a world of odd two-legged creatures, and for some reason they're all obsessed with a card game called "Duel Monsters." Twilight soon learns that the only way to get her crown back is to win it in the school's semi-annual duel tournament, of which Sunset has been the reigning champion three rounds running. The tournaments have divided the school, and split up a group of five friends similar to Twilight's friends in Equestria.

Twilight now faces her biggest adventure yet. She must master Duel Monsters, reconcile these other versions of her friends, and defeat Sunset to win the Autumn Crown. And she has only three days to pull it off. It's time to duel!

Pinkie Pie is visited by a strange customer whilst working at Sugarcube Corner. Hilarity ensues.

The Night Guard was once a highly regarded order, and joining the personal servants and defenders of Princess Luna herself was one of the most prestigious positions anypony in Equestria's armed forces could aspire to. Then the Princess of the Night had her little run-in with jealousy-induced insanity, and her subsequent banishment left the Night Guard in a bit of an awkward position.

Fortunately, the fact that the Night Guard was not really needed anymore never seemed to occur to anyone, and now, a thousand years later, the order is still just sort of... there. However, after centuries of neglect and a complete lack of supervision, the Guard barely resembles a military organization anymore.

Some unquestioning military bureaucrats apparently still take care of pay and hiring, and every now and then, new recruits arrive with purpose in their step and stars in their eyes, convinced that service with the Guard will allow them to achieve great things. But while those hopes unavoidably end in disappointment these days, recruits tend to acknowledge soon enough that the current state of the Guard does have its perks.

The only thing that could possibly ruin this cushy little job would be the return of Princess Luna. But it's been centuries since she was banished, and really, at this point, what are the odds of that ever happening?

A little just-for-fun side project I did a while ago over a pretty short period of time.
Be warned, within this tale you will find:
- references to excessive alcohol consumption
- juvenile and cringeworthy innuendo
- shenanigans
May also contain trace amounts of bat ponies.

Expertly proofread and edited by the hawk-eyed, diligent, and just all around [insert positive adjective of your choice] 0_0.

For better or worse, characters are defined mostly by context. A horrible monster in one story might be a hero in another. A minor hurdle in one world could be an insurmountable problem in another.

So a gap that allows characters between two contexts might be more of a problem then it first appears...

No knowledge required of A Certain Magical Index, or A Certain Scientific Railgun. (Hopefully...)

This story can also be found on Spacebattles, Fanfiction.net and Archive of Our Own.

Straight from the Canterlot archives, this collection of documents retells the rise and fall of Princess Twilight Sparkle, Enlightened Despot of Equestria, Defender of the Peace, Lawgiver, and Commander of Fort Libris.

Twilight Sparkle is, of course, known to historians as the first usurper to seek to schedule a coup d'etat by appointment. But for other details- such as, "What is the longest recorded time a pony has gone without sleep?", "Is it true what they say about swans?", and, "Why is there an owlbear in the Equestrian Witness Protection Program?"- these documents provide the answers and much, much more.

This is ABSOLUTELY SERIOUS HISTORY from primary sources. If anything makes you think this is silly, ludicrous, or unbelievable, blame Discord.

Part of the Remember Fort Libris print anthology, thanks to our Kickstarter supporters!

Years ago, Daring Do discovered an ancient city, forgotten in one of the farthest reaches of Equestria, and within it a mysterious lock that could not be opened by a single pony alone. Frustrated and eventually defeated she was forced to abandon her find, willing time to absolve her of her failure.

Not too long ago, she met a pony named Rainbow Dash. A pony who helped her.

Now old memories are rekindled when Daring learns that a longtime rival has uncovered the city's location. Forced into action, she sets off on a race against time to beat her competitor, and finally learn the secrets it undoubtedly holds. But this time, she'll succeed where she failed all those years ago. This time, she'll have help.

Lyra Heartstrings, transformation specialist and social worker for those who believe they were not born ponies. These are her therapy sessions, both in group and in private.

With a little gentle guidance, these lost souls can rediscover the joys of being a pony, and let go of their foolish ideas. What sorts of trauma would drive anypony to throw away their identity?

This story is a sequel to The Application of Unified Harmony Magics

  After the incredibly awkward reunion last night, Sunset is less than eager about her promise to introduce Twilight Sparkle to Princess Celestia. Maybe it would help if Twilight could go more than five minutes without a panic-driven ramble.
  Despite her doubts, Sunset decides to do her best. But between a bowl of ice water, Philomena’s antics and Celestia’s sly smile, Sunset knows this isn’t going to be easy.
  Still, Twilight probably could have handled it better.

Strongly Recommended Stories:
The Brightest and the Best by Pineta - The events in this story are considered to be completely canon to this timeline and explain Twilight's entrance exam to Celestia's School for Gifted Unicorns. I cannot recommend this story enough.
MLP Annual 2013 - "The Fall of Sunset Shimmer" - As above, the 8-page short comic in the beginning of the Annual is also considered to be canon, though with some major variations.

Version 3.0 Edit: Extensive grammatical and mechanics changes. Adjustment to timeline of Sunset's second mirror experience.

This story is a sequel to Princess Celestia: A Brief History

  When Celestia first laid eyes on Twilight Sparkle, she knew she’d seen her somewhere before. Though she’d managed to hide this from both Sunset and Twilight, after they departed for the evening, Celestia needed to be sure.
  With her trusted aide Raven at her side and a dangerous threat on the horizon, Celestia heads to the offices of the Equestrian Secret Service to investigate her suspicions.
  Because if she’s right, the possibility of eternal night is the least of Equestria’s concerns.
