This story is a sequel to What Follows Hugs

A foal is found lost in the snow, the tsuki, warm-hearted rabbit folk, take him in just long enough to realize he may belong to the ponies nearby. His name is Harry, and his fate was knocked a little off course.

Set after What Follows Hugs, but we're likely to wander away from our rabbit friends, as a young Harry Potter needs to be taken care of by other ponies. He is a pony, right?

This story is a sequel to Rider on the Storm

For the briefest of moments, Anonymous wielded absolute power. He single-handedly destroyed the city of Canterlot, laid waste to Ponyville, decimated the Everfree Forest, and came dangerously close to annihilating the very Tree of Harmony itself. And he had an absolutely fantastic time doing it.
Right up until he lost.
Now he's stuck as a statue under the watch of the princesses he tried to subjugate, awaiting the time he'll be locked away forever, with the key no doubt thrown into a volcano. But from the very beginning, Anonymous suspected that the shenanigans of the good guys would cost him his victory at the last moment, and so he laid plans with his most loyal of subjects—all former soldiers of the Storm King he betrayed to obtain his power—to arrange for his release should the opportunity arise.
Unfortunately, he wasn't counting on the ponies calling in help from a faraway land. Enter the Four Princes of Zebrica, all wielding the same exact power that Anonymous did, and knowing a thing or two about how to put bad apples like him away for good. This is made even worse by the sorry state of Anonymous's storm beast forces, having hit hard times in the months since his defeat.
But not all is lost for the petrified supervillain. Because in a rare twist of luck, the Princes just so happen to unknowingly bring with them a zebra criminal with his own dirty little secret. A secret that not only secures Anonymous's release from captivity, but just might be the start of a horrifying new partnership, and with it, the birth of a new force of evil.
And of course, with all that going on, there's always the matter of the nascent Legion of Doom, plotting to bring their own age of darkness to Equestria as well...

Takes place during the final two seasons of Friendship Is Magic. With a few alterations here and there, because I HATE THE ANTI-FIM I HATE THE ANTI-FIM :bread:
Reading Rider on the Storm is strongly advised if you want any idea of what the hell is happening in this story.

A cynical and distrustful man has a drunken conversation at a bar with someone and finds himself waking up in a land of talking ponies the next day. The catch? He's now a Ninetales. "Great...where's the bar?"

My attempt at a more serious 'Luna meets Neil Armstrong' storyline. What would really happen, both on the moon and on Earth? Inspired by 'The Eagle has Landed' by CyanBlackStone.

Princess Luna has found herself on a very different moon after some strange force interfered with her banishment. She doesn't know what the metal objects that keep orbiting and sometimes landing there are, but she wants to find out. Meanwhile, Neil Armstrong believes that being the first man on the moon will be the crowning achievement of his life. Hoo boy, is he ever in for a surprise.

For those who are interested, the most excellent Zanec has provided this link to an interactive Apollo 11 site.

This story is a sequel to Twilight Gets a Puppy, Season 6

The Sparkles have just finished a year long prank war with Celestia by order of ... pretty much everyone that currently exists and a few who don't, but this filler season brings more problems. Though the battle for Rahs' heart heats up, the cutiemark crusaders kick it into high gear to get Sweetiebelle her mark, Sunset sets things on fire, Pinkie Pie, there's another God Summit coming, an ancent pain in the ass returns, and some pony gets proposed to, all in this filler season of Twilight Gets a Puppy.

This story is a sequel to Cross the Rubicon: Choices

From the beginning, Spike was there, watching, listening...knowing things that he could tell no one.

He knew something bad had happened. He knew something was off about Sunset Shimmer. He knew something was hurting Twilight. But no matter how much he barked or howled, he could never explain what he knew to anyone--they would never understand him.

It didn't mean he wouldn't try.

He would give everything he had to protect his human.

A companion piece to my main story, Cross The Rubicon: Choices , from the perspective of Spike the dog.

Late one night, several months after the events of the Fall Formal, Sunset calls Rarity at a frankly unreasonable hour. Things go from there.

(This was originally a standalone one-off thing. The list of sequels is starting to get lengthy, so I decided to compile them all together as one thing for neatness's sake.)

In the far reaches of Canterlot Castle, high above in the towers lived the archmage. Everypony knew her, yet few had met her.

Twilight Sparkle sighed, having teleported away another noble seeking favors before reaching the top of the stairs for the second time today. They never learned. As the archmage, she already dealt with political squabbles far too often without inviting them into her home. Aside from personal favors for Celestia, she did what was required of her position and then returned to seclusion and research.

The nobility grumbled that no archmage should be a commoner, and Twilight’s disrespect toward them proved it. Each and every time they were forced to bow to her, they hated what they saw: the position, the status, the deference.

Was she not powerful? Was she not great?

Twilight, now reading through dusty scrolls and long forgotten tales, wrote in her notes — notes gathering dust of their own. A brief thought flashed through her mind.

Am I not powerful? Am I not great?

And then Twilight picked up The Tale of the Royal Pony Sisters.

Defunct side stories told in Across the Boundary. They can still provide a little context, but when in doubt, the main story here is canon.

Most of ponykind didn't think much of the space far above their heads, until a record from another world fell from the skies.

To escape from Tartarus is nearly impossible, even for one of great magical power. When you've lost your powers and are little more than a withered old centaur, it's even harder. But Tirek has a plan, one that will draw in a creature from a world where life is cheap, hats are plentiful, and gravel is king. Will the Spy take the opportunity to enjoy a well-earned vacation in this new world, or will he see the population of friendly, innocent ponies as just a fresh selection of backs to stab? It could be both!

(Takes place before the beginning of Season 9.)
