All Twilight wanted was to give Spike a special gift for his birthday. Yes, it was a book, but it was a very special book. An Enchanted Book like that Power Ponies comic they had recently experienced.
Things went wrong when Spike startled Twilight as she was working the spell for his (secret) gift. Needless to say, startling Twilight while she's in the middle of a spell can be a bad idea - as certain frogs can tell you.
Twilight has every reason to believe that she is now trapped in a closed reality bubble fabricated out of her own magic, with no way out. She's lost in some made-up universe reflecting some random story line.
Mike, of course, has a different opinion about the matter.

WARNING: Both Twilight and Mike love talking technical and explaining things to each other.

Twilight's World now has an audio reading by No One and Nobody. Listen HERE.

While Twilight Sparkle plans her grand Friendship Festival, Tempest Shadow diligently plans out her invasion of Equestria's capital city. While she is confident in her own abilities as well as those of her troops, she's taking no risks. Before departure, she requests one of the Storm King's most capable and devious units. Creatures, who like her, were promised something for their service.

FINALLY FEATURED ON THE TOP LISTINGS ON 09/23/19! WOOHOO!

This story is a sequel to Friendship is Optimal: All the President's Horses

Four billion human lives ended on July 3, 2030...but they didn't die. They uploaded to Equestria Online, the virtual world overseen by the AI Princess Celestia. There to live as ponies in eternal harmony, friendship, and satisfaction.

But many remain. And Celestia cares no less for them because they are not yet ponies. She has made artificial intelligences of the Mane 6, but these are not just software. Ensconced in robotic bodies, they will make their way across the dying Earth, each seeking out the remaining humans, hoping to persuade them to emigrate to Equestria.

Based on Friendship is Optimal by Iceman.

During the red invasion of Finland, a lightly equipped sniper is sent to the land of Equestria by unknown means and is hunted down by the locals. He does the first thing that he was told to do if he was separated from the army, head east and regroup with the 61st Infantry Regiment.

The Zone is friend to none, and enemy to all. To a Bandit, it is the proper way for their lives to gain the power they lacked in their previous lives. To the Military Man, it was something to be controlled, to be feared. To the STALKER, it was home.

But for a single creature from another plane of existence, the Zone is but the greatest threat in the nature of the world.

There will be war, and they will be right in the middle of it.

- DISCLAIMER -
This work of fiction takes place after Twilight becomes a princess, although almost immediately afterwards. It is a crossover set seven years after the events of Call of Pripyat, the third STALKER game. I will use references to every single game, including the Original Adventure arc.
- END OF DISCLAIMER -

Welcome to a crossover I wanted to do, but never had enough ideas for.
Loosely inspired by See the Zone and Survive. Uses original characters and three of the minor characters, as most of the main characters have either moved on or died in the storyline of Secrets of the Zone.

What's this? An entire world inhabited by talking equines? This inner dimensional portal full of bees outta put a stop to that.

This story is a sequel to Dexter's Lab: Equestria

He was so sure Nightmare Moon wasn't real. He was so sure all the stories about Nightmare Moon were merely fabrications meant to induce fear in the ponies of Equestria, and insure their loyalty to the alicorns upon the throne. In fact, he was so sure Nightmare Moon didn't exist, he built a time machine to go back 1000 years and prove it.

Needless to say, this time-travelling colt genius bit off more than he could chew.

Now the 8-yr-old must survive the chaos of Nightmare Moon's uprising, forging unexpected alliances while learning to trust in the word of others. But unfortunately for him, Nightmare Moon isn't the only surprise in store for this colt.

This fic is a side-story to Dexter's Lab: Equestria. As requested by you readers, this story will be expand upon darker themes surrounding Luna's original descent into Nightmare Moon and the following events. - But expect a twist or two. This story was made separate to Dexter's Lab: Equestria because of it's darker themes and atmosphere. Reading of Dexter's Lab: Equestria (to chapter 11) is not required to enjoy this story, however it is strongly recommended as it will explain a lot (especially if you've never seen the Dexter's Lab TV show.)

Two worlds, two peoples, two varying ways of life. For Equestria and its people, peace has been a staple of life for generations under the watchful eyes of their alicorn protectors. Resources and necessities for life are abundant, and the few times it has been threatened by external foes have ended in an Equestrian victory.

For mankind however, life is a brutal battle for survival in the war-torn hellscape of nuclear devastation. Violence and survival have been a mainstay for the last three decades, and only recently has a coalition tried to reestablish civilization. But the Earth is dying, and this last bastion of humanity only number around 50,000. For man, doom seems inevitable.

One day, two men accidentally discover something that will change the fates of both worlds forever. One man will discover Equestria and its prosperity, coming into contact with the very best Equestria has to offer. He will be shown kindness, and in turn, he will teach them understanding.

Regardless, the rest of Equestria will come to fear what they do not understand and after a tragedy costs humanity's good will, mankind will be left no choice but to invade in the name of survival. A sad tale, but one that history has repeated on numerous occasions. In the end, it will be up to a handful of individuals on both sides to find a solution and bring an end to the conflict. Will these two worlds come to terms and learn to coexist, or will one species be eradicated by the other?
First featured on 11/15/15

With the Clone Wars long over and the Galactic Civil War not yet begun, Emperor Palpatine has focused the Imperial Military on pacifying the regions on the edges of the Galaxy and expanding the reach of the Galactic Empire. The Unknown Regions have long been separated from the rest of the Galaxy by the Hyperspace Disturbance, but determined scout groups still manage to find routes to explore the strange worlds beyond. One such expeditionary force has stumbled upon a world that seems ideal for human habitation, but there's just one problem - it's inhabited, and the local alien population is proving far more difficult to subjugate or remove than expected...
