In every event, there are a million offshoots and effects, none really able to be fit into a normal narrative. Here is a collection of one-shots and mini-arcs spun out of The Elements of Harmony and the Savior of Worlds, so knowledge of that series will help immensely. Although I will do my best to make it as accessible as possible.

NOTE!:
All side-stories so far take place after the end of The Elements of Harmony and the Savior of Worlds.
The cast will be varied, as will be the stories, but all are canon.

Chapter One: A Picnic by the Lake: Celestia, Luna and Twilight entertain a guest who is more than meets the eye.
Chapter Two: Time Enough for All: The Doctor has spent nearly nine hundred years in Equestria, most it an extended vacation. But news of giants in Ponyville draw him out of semi-retirement.
Chapter Three: Contact Part One: Old Memories: Chip delivers the Princess' message to President Abernathy, which stirs old memories.
Chapter Four: Contact Part Two: Meetings and Greetings: Equestria makes formal contact with Earth, and an old mystery is finally put to rest.
Chapter Five: Family reunion Part One: The Best of intentions: Dinky sets out to reunite her father with his closest friends, roping her sister and the rest of the Cutie Mark Crusaders on a journey across time and space.
Chapter Six: Family Reunion Part Two: Memories: The TARDIS arrives at Earth, reuniting the Doctor with his past.
Chapter Seven: Shape up or Slaughter Out!: Shining Armor gets some help from an old warhorse to finish what he started with the Royal Guard.
Chapter Eight: How Christmas was Saved... Sort of: A short tale of how Santa Claus was saved one Christmas Or Megan had too much eggnog.

Equestria Daily page: A man can dream...

It occurred one peaceful night. Half of Equestria awoke to the sound like a double-shot thunderclap. A percussion heard in the skies and rattling windows from Apploosa, to Canterlot, to Ponyville. Nopony knew what it was or what it heralded for the world as it drew a line across the nation.

For Twilight Sparkle, this isolated incident might have faded from memory after a time, if not for the strange rumors of a creature sitting on the hill on the outskirts of town.

These are her thoughts given written form. These are Sparkle's Notes.

Report EVERYTHING to the Princess.

Think of everything you hate about people online. Now bundle up all those bad traits and throw it into a pony. You now have Caps Lock: an over opinionated, egotistic pony that simply enjoys the anguish of others.

Now throw that pony into Ponyville Elementary School, and you get this story.

Rated Teen for some course language, mature themes, and overall inappropriateness.

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.

We were the summer-sunset-wind, warm and wild and untouchable.

We were rulers of a crumbled-down kingdom, prince-and-princess of the sandstone sky.

We were long-day shadows, stretching ourselves dark and blurry past our breaking points and more.

We were pulsing breath-and-blood, flowing fast through veins of buildings and wide-open spaces.

We were rebels rivals friends lovers runners...

Until that moment, that second, when it all fell away.

A refined mare fresh out of high school and a dropout following her dreams find themselves forced to spend a lot of time together.

With the help of a meddling psychology tutor and their new classmates, can they find what they've been looking for?

Fan Stuff!

Ever since moving to Ponyville, Twilight has neglected something: her other residence. The rooms she used in the Canterlot Archives are still filled with her possessions. It's been nearly a year, and the Archives want her to clear out already so the place can go to the new departmental librarian. She has until sunset -- or anything still there just might remain so. Spike, knowing the deadline is hours away from arriving, recruits the Bearers to help her.

But Twilight doesn't want help.

A deadline is in front of her, and she's -- stalling.

They have until sunset...

This story is a sequel to Kind Hearts & Coronets

“My name’s Daisy Jo Martinez. I was born – or so my birth certificate says – on March 30, 2012. I’m married with two kids, my husband’s a Naval officer. I’m originally from a town just outside of DC called Winchester, Virginia – apple capital of America, yay, go me. I’m a Republican – that tends to shock a lot of people – and I’m a practicing Catholic – and that tends to shock more people than the first, and like I said, I’m married – I think people start passing out at that point. I've lived a happy, charmed life and I’m proud to be an American.

“And as you can also see, I’m a pony. Well, physically anyway."

The first main story of The All-American Girl Saga.

Sometimes, things don't go exactly to plan. Other times, you tick off the wrong planet alltogether.

A collection of short stories and snippets that show us what would've happened if the Equistriani Barrier had had the misfortune of appearing on the wrong Earth, crossing over with other media.

THIS IS AN EX-FANFICTION!!

For little less than one thousand years, the species of Equestria had been a part of the Trade Order, sharing the millenium of peace of prosperity the humans had enjoyed.

Now, with the arrival of alien invaders and the return of ancient evils, that peace was been shattered. A people unused to war had to rediscover its ways and fight for their home. The Trader Emergency Coalition was born from this need.

Ten years have passed, and the sitation has improved to the point High Command has authorized a rotation of the forces, sending the weary first generation back to their homes, to rest and recover.

Meanwhile, a lavander unicorn mare who has never been on a planet is travelling to Equestria on behalf of her teacher...
