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.

==Originally written spring 2011== Equestria Daily Post==
GLaDOS is free of Chell, free to continue testing, when she discovers a portal gun Wheatley tried to repair with duct tape. When the portal gun catastrophically fails, the enrichment center, GLaDOS, and Chell are literally dropped in the middle of Equestria. The mute test subject soon finds the world of ponies far more welcoming than the human world. But GLaDOS sees possibilities. Let the testing begin... for science.

Mort, also known as the Pale Pony (of Death), has been tasked to take time off from his rigorous duties of reaping souls. Seeking guidance, he is directed towards the town of Ponyville, to learn about the magic of friendship from Twilight Sparkle and her friends. All he needs to do is keep his true nature a secret. That shouldn't be too difficult...right?

Special thanks to Specter-Von-Baren and Pyrite Foolsgold for their help in proofreading and editing this story, as I really needed it. Additional thanks to Pilate, Chuckle5, Unimpressive Vagaries and Admiral Biscuit as well! Couldn't have done it without all their help!

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

Crossing street + Hit by an 18 wheeler, should not equal being alive in a dungun, let alone with the bug out bag you had created for a zombie attack. Rick Rogers is in the strangest place, and after hearing the guards about executing the prisoner, an escape was never easier that with the things in side that bug out bag. After his escape he finds the world he is in, is not his own and what looks like what use to be a peaceful place is now in a civil war. The Solar Empire VS The New Lunar Republic.
(this story is a human version of every character that means human mane 6 human Luna etc.)

This story is a sequel to Past Sins

Hearth's Warming is a time for friends and family to come together, celebrate harmony, and welcome the new year. Nyx is looking forward to just this as she rides the train to Canterlot with Spike and Twilight. She's going to meet her extended family for the first time and wants nothing more than to make a good impression. Yet, the sheen of the holidays can't hide the trouble caused by meddling grandparents, relentless reporters, and a paranoid uncle.
