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)

An indirect sequel to “My Little Staring Contest: Alicorns can stare for a very long time.”

Discord is a new draconequus now, and sworn to use his powers only for good, but that doesn't mean he can't still have some chaotic fun while on the job. Tasked with helping to reform a pair of thieves hiding out in an abandoned apartment building, the Spirit of Chaos decides to make a game of it. Two lost souls find their lives on the line as they gamble their freedom in a battle of wits against a grand master, in his own House of Chaos.

Part of the Borderworld.

Twilight Sparkle is a gifted student and scholar. When she attempts to harness her creative side by writing a science-themed sensual romance novel, however, things rapidly get out of hoof. Can her friends stage an intervention before she humiliates herself (and them) at a prestigious literature recital?

No. No, they cannot.

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?

My eternal gratitude to my editor, LordOfTheWrongs, without whom Night's Favoured Child would not be the story it is today.

Now with added TVtropes!

I've spent the majority of my life tilling the desolate land in which I live. Every day, I wake up to move useless rocks from one location to another. This is an archaic line of work that my family has clung to for generations. It is a dull, grey existence.

Today, I have woken up in a strange room, lying in a bed that isn't mine. I'm surrounded by five mares whom I've never seen in my life. They claim to be my friends, and expect me to bring joy to the hearts of everypony.

Joy? I don't think I've ever experienced this for myself, so how am I supposed to thrust it upon others?

My name is Pinkamena Diane Pie, and I'm not sure what to make of this situation.

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

WANTED:

The newly crowned Princess Twilight Sparkle has set up a bold new initiative to discover new magic, and is sending out an open call to the unicorns of Equestria to apply for her research team. No experience in magical theory or research necessary. Enthusiasm and out-of-the-box thinking a must. The Equestrian government is not responsible for any physical, emotional, or magical trauma experienced during the course of the project or the application process.

In Equestria's far future, one thousand and five years after the return, a dysfunctional group of argumentative ponies must quest to defeat the most dangerous enemy of Equestria to ever live; the malevolent Lord Second, one of the only known members of the race of elder gods known as the humans, and the ancient cult who worships him, the Brotherhood of Man.

An over-the-top surrealist comedy, with slight serious elements. Expect a steady decline into insanity.

Cancelled, due to reasons of severe cranial trauma

Now with audio reading and prequel story, Shades of Grey, by Draven Eclipse.
