A human has arrived in Equestria with one purpose. Oh look, how original. But... It's not to make friends? Not romance? And he didn't die? Why then, did he come to the land of Ponies? Personally, he blames Obama.

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.

"Princess Celestia cordially invites you to the divorce of Princess Mi Amore Cadenza and Shining Armor!"

Twilight rushes to Canterlot to figure out the meaning behind this letter, only to find a den of lies and greed.

When Queen Chrysalis was defeated, she was blasted to the inhospitable Badlands. Separated from her army and starving for lack of love, Chrysalis is rescued by an unknowing pony who points her in the direction of the nearest town: Ponyville. As the battle-worn queen treks to the small town, she decides that she is tired of fighting a losing battle and would rather just settle down and live a normal life. But old grudges don't just lay down and die, and Chrysalis somehow managed to choose the one town home to all six of the ponies responsible for her downfall.

Rainbow Dash isn't bitter about the whole Mare-Do-Well incident. Or at least that's what she tells herself. Either way, she's not going to miss this chance for some harmless revenge pranks, and so she constructs a plan to prank all of her best friends, starting with Twilight Sparkle. All Dash needs is a quill and some paper.

Thanks to the amazing DShou for the cover image.

As the personal protegee of Princess Twilight Sparkle, Luna's life is more than crazy enough for a unicorn of her age. Balancing her studies and putting up with her hard-partying pegasus sister is enough to keep Luna up most nights with little or no social life to speak of. But as the only one who believes the legends that Tirek the Terrible is returning and the only one who actually cares enough to stop him, it doesn't look like Luna is going to be getting any sleep anytime soon.

Which is just as well, because she keeps having the strangest dreams about a life she half-remembers; a life of long nights spent as Princess of the Moon and a terrible catastrophe that befell her kingdom. But those are just dreams...right?

With the fate of Equestria resting on her shoulders, Luna must unite a group of unlikely allies to stop Tirek, save the world, and solve the riddle of her nightmares before they come to life.

Hidden Fortune and her sister grew up in the Wasteland, learning its dangers and doing their best to stay out of sight and out of mind of the larger world. During a treasure hunt they discover a Stable, and a chance encounter changes their world. Now the sisters must travel out of their element, learn how to survive all over again, and hopefully, discover the one true treasure of the Wasteland.
