A terrible affliction has befallen the peaceful town of Ponyville, and the lavender unicorn and her friends are right in the middle of it! And the edges of it. Heck, it's pretty much lavender unicorns all over.

A story unrelated to anything.

New adventures and new worlds. The Elements of Harmony decide to explore the magical mirrors within the Crystal Palace to gain knowledge of the different worlds. Stepping through a portal again is exciting for Twilight and new for the other five. But landing in this new world was anything but good for the Mane Six. Now they're all stuck here as...

Humans.

Great.

Celestia and Iroh share some afternoon tea and sagely advice over a game of Pai Sho.

Credits for original idea and editing go to my good friend Cthulhu.

This story is a sequel to More than Forty Blinks

Zecora has warned Star Swirl the 147th not to visit her homeland, but the alure of so many races weilding so many types of magic has made Zebrica too promising a location for Star Swirl's first trip out of Equestria. Why does Zecora fear for this trip? What secrets does the King of the zebras hold? Story three of the Truthseekerverse, but probably possible to read before the others.

This story is a sequel to Better Living Through Science and Ponies

THIS STORY IS CURRENTLY BEING REWRITTEN. PLEASE READ:
I've decided to rewrite this entire story. Considering that I began this project with almost no creative writing experience, I was bound to make some pretty bad mistakes. The story flow is not well organized, and there is an unhealthy amount of redundancy and poor pacing, as well as some pretty important things that I should have included. I intend to address these issues to the best of my ability, but it will be a long and arduous task. This story means a lot to me, so I want it to be more than the mere amateur mediocrity that it resembles. So, give it a read if you want, but keep in mind that it will change. I recommend that you put this on your read later list in the meantime.

This is a Portal 2 crossover. If you haven't played Portal 2, please do that first. Then read the prequel if you haven't done that either.

After Chell finally escaped the confines of Aperture Science, a freak portal mishap down below transported her, along with the entire Enrichment Center, to the land of Equestria. Upon entering this world, she was transformed into a pony. In a strange body and in a strange land, Chell was fortunate enough to be accepted by the ponies of Ponyville, and she lived out a new life contently among the ponies.

But that peace was not to last, for GLaDOS took a particular interest in the ponies of Equestria, and after two weeks of preparation, she launched a surprise attack and kidnapped 300 ponies to serve as test subjects, including Chell's friends and the princesses themselves. Once GLaDOS had them, she subjected them psychological torture. To save her friends, Chell made her way into the one place she hoped never to see again. In doing so, she freed the ponies, defeated GLaDOS in battle, and helped bring about the destruction of the facility. Although this made Chell a hero, she paid a terrible price in that brutal fight.

Beaten, battered, and traumatized, Chell spent months recovering from her wounds. After returning home from the hospital, all she wants is to once again live a normal life in Ponyville, but to do that, she must first heal from her wounds, both physical and psychological.

At the same time, GLaDOS herself has survived Aperture's destruction. With nothing left but herself, she vows to get back to testing. Though she faces an uphill climb, she is determined to see her facility rebuilt and the testing resume, and will stop at nothing to achieve this.

Has a TV Tropes page (will need to be updated after rewrite)

The works that this fanfiction is based on are properties of Hasbro and Valve. I would like to thank Pen Stroke for writing the original story and Flyer for his assistance and advice.

Please note, this is an unofficial sequel. I have received permission from Pen Stroke, but it is not canon to the original. I hope you enjoy it, but keep in mind that this is a fan work (of a fan work), and Pen Stroke holds the rights to the original story.

This story is a sequel to The Best of All Possible Worlds

In school, everypony learns about the official history of Equestria, the acts of heroes and villains that made the world what it is today. But at home, everypony learns another, secret history, about how their family and theirs alone is at the center of Equestria's history, and how without them, the world will fall apart. This Hearth's Warming Eve, Twilight Sparkle and their friends will share their secret histories, and in this way discover that the bonds between them reach back far earlier than Rainbow Dash's first Sonic Rainboom.

This is a follow-up to my earlier story, "The Best of All Possible Worlds". That story was set centuries in the past, while this story is present day. If you're wondering where the humans came from, see another side story that is otherwise unrelated to this, "Parade Coverage". Despite that, I expect that this story stands alone. The story's set in an alternate-universe Season Three that branched off early in Season Two.

I don’t question the “life” bar floating over my head, or my “EXP” gauge, or the little phantasmal boxes that appear whenever I look at an “equippable” object that show its “statistics.” It’s normal for small messages to appear in the sky every now and then, such as [System update in 2 hours.] My kind worships the Developers, higher beings that direct, create, and control everything we see. It’s all normal. This is how things have always been, since I was born. My father, my grandfather, my ancestors have all accepted and coped with these elements.

So why does everything feel so... fake?

My name is Twilight_Sparkle, and I know there’s something wrong here.

Co-Written by GaruuSpike and Chaotic Dreams.

(EDIT: This story is cancelled forever because someone sabotaged all of our attempts to write. You know who you are, and so do I, and I hope you're happy for killing it.)

This story is a sequel to Gotta Dash 'em All

After much anticipation, Twilight has finally succeeded in designing a teleporter capable of sending ponies to the Unova region. Unfortunately, a trio of mischievous fillies decide that this may be the perfect opportunity to get their Pokémon trainer cutie marks.
When the mane six discover that the trio has used the machine, they follow them to the Unova region for a rescue mission. Can they find the Crusaders before it's too late to save them from themselves? Stick around to find out.

As Rainbow Dash attempts to break new barriers of speed, she finds herself transported to a mysterious world, inhabited by creatures with unbelievable powers. While her friends in Equestria search for a way to return her home, she is forced to search for her own way home with the aid of her new friends, a trio of humans named Ash, Cilan, and Iris.

This story is a sequel to The Best of All Possible Worlds

For generations, humanity has dreamed of discovering intelligent life out in the stars. To say that ending that search in downtown Pasadena was a surprise would be an understatement.

Princess Luna had herself a simple mission: Track Twilight Sparkle and her friends through a malfunctioning portal to Earth, and get them out without being noticed. Luna had no desire to establish permanent relations, or even to stay and talk. After all, both princesses were convinced from previous experience that humans were nothing but trouble.

It appears that both parties have much to learn about each other.

Present-day follow-up to "The Best of All Possible Worlds". "Alternate Universe" tag is because it pretty quickly diverges from Season Two continuity.
