==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.

Let M'aiq tell you of a short story, where he was trapped in place that he could not remember. Full of colorful ponies, some with green coats, others with purple coats. They come in many colors. M'aiq wishes his coat was green, it's his favorite color. Anyway, he meets two princesses, they send M'aiq home. The End. Well. They did send him back but it wasn't home. Then, he gets sent back. So it continues!

Now with more gore

Many years ago, shortly before the birth of one Twilight Sparkle, Celestia, ruler of Equestria, found a small item in a forest. That item? An egg. Around the same time, in another place, Celestia, ruler of Draconica found something small in a forest. That thing? A pony.

Spacetime accidents-
A foreign invasion-
Friends with stuff to haul-

The new 2013 Applejack can handle all this and more!

A young inventor named Tinker has her life turned around with the arrival of a mysterious mare in a crimson cloak and a tattoo in the shape of a draconequus that runs the length of her body. When their fates become intertwined, Tinker will travel through time and space with the pony once known as Twilight Sparkle and witness the nature of her universe and the ponies who inhabit it.

In the dark,six voices dwindle. They drift, forgetting life and love and hope, eaten away by time and void.

And then, suddenly, there was colour.

"My dear Twilight Sparkle,

Thank you for your recent letters. And I must apologize to you first and foremost that I have not responded back in kind to each and every one. I imagine has this concerned you, but please don't worry. Things have been very unsettled here in the castle as of late. Princess Luna has been researching Equestrian history, and I find myself in a strange kind of mood..."

While moving to her new home, Zecora find the strangest creature - a large, nigh-hairless talking monkey-thing. Seeing how it lacks basic knowledge on surviving in the wild (and that it's quite tall and probably good at manual labour) she decides to adopt it as her assistant. Hopefully, she won't come to regret her decision.

This story is a sequel to The Longest Night

As her twenty-first birthday dawns, Twilight Sparkle finds her simple life turned upside down. While her birthright forces itself into her life, Twilight also has to deal with the arrival of three Alicorns. No pony knows where they came from or what they want, and the Alicorns seem intent on keeping themselves and their purposes hidden. To uncover the truth, Twilight will set sail for distant, ancient lands with old and new friends.

Twilight Sparkle has always admired Princess Celestia. Her fortitude, her wisdom, her eternal grace and love for all her subjects. Twilight has often fantasized about what it would be like to be in Princess Celestia's horseshoes. She never imagined those fantasies would come true.
