The newly coronated Princess Twilight suffers an abrupt tragedy. Having lost two loved ones, she begins to question her own mortality, and that of her friends.

AJ, Dash, Rarity, Pinkie, Fluttershy. . . they are just the beginning. Twilight will live for thousands of years, so every pony she cares about—every pony she will ever care about, will die.

She could barely handle the pain of one funeral, let alone the thought of hundreds of them. Twilight finds a clever way to ensure all of her friends never die. They can’t all be ageless alicorns, but they can all move into Twilight’s Dollhouse. Then they can be best friends forever.

TD, the human that first showed up in Equestria in No, I am NOT a Brony, GET ME OUTTA EQUESTRIA!!! is depressed that he's stuck in the world of ponies with no way home, but finds solace in helping Cheerilee teach her class. However, Cheerilee is sick with the flu one week, and that just happens to be the week that a teaching supervisor comes to the small Ponyville classroom. From the very beginning she has doubts that TD is a person fit to teach the future generations of Equestria. Should TD fail to meet her standards, he will not be allowed to teach them anymore.

Non canon in the Non-Bronyverse

Rainbow Dash is dead.

Scootaloo knows this, but that does not mean she will accept it. Equestria is a land of magic and hope—what is one more miracle among hundreds? This is the question that drives her forward when she stumbles upon a Daring Do book that seemingly shows her a means of bringing back the dead. Driven by painful memories and a desperation to make up for her own mistakes, Scootaloo ventures on a quest to bring her fallen idol back to the land of the living. Embarking on a journey far from the world they know, Scootaloo and her friends find the line between fact and fiction—reality and delusion—blurring with each step.

Princess Twilight Sparkle has a problem: she's possessed by a question. It came from a silly little book. Now, after a week of poor sleep, Twilight relents. She has to answer this question, even if it kills her.

Okay, so it won't kill her, but Twilight is going to have to violate one of the biggest pony taboos in existence to do so. That's okay. It's for science!

original author wille179

In a world without bacon, five humans find themselves trapped... grazing on mother bucking dandelions. To get home, they'll need to learn that friendship is magic. Too bad none of these jerks are friends.

My unicorn parents called me a worthless mud pony. They pushed me every day to overcome my lowly status. When I woke up one morning with my cutie mark, I thought they would love me. I couldn’t have been farther from the truth.

It was not destiny or enjoyment that led me to discover the cello and composing. My parents made that decision, deciding before I was born I would continue their family legacy of famous musicians.

They did not realize what that decision would cost them.

Each night I’m trapped in the dark, immobilized. I hear whispers as they operate on me: they say I shouldn’t be alive. Twilight refuses to tell me about the operation. Sometimes she can’t look me in the eye. What did they do to me?

Nothing used to scare me: I kicked a dragon in the nose, defeated gods of chaos and hatred, and control the weather. Now I feel broken. My memories have shattered, I feel wrong, and I’m afraid to tell anypony how scared I am.

I can’t even do the rainboom anymore. Who am I? I’m no longer the best flyer in Equestria, yet everypony assures me I am. Why won’t they tell me the truth?

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.

Luna starts up a Judge-Judy-like show. But, as time goes on she slowly starts to waste away from some unknown illness. Stubborn as she is, she won't allow it to keep her off the throne dealing with her duties as Princess. Will Equestria watch as she wastes away to nothing, on live television?

There was only one explanation. For all of it. All of the strange, erratic behavior. Her irrational fear of the sun. Her nocturnal habits of locking herself in in the dark and closing all the blinds. Wearing her sunglasses everywhere, even inside! It was time to invest in some silver, garlic, and a wooden stake.
