==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.

Rainbow Dash is grounded by a storm in Ponyville. She finds sanctuary within the library but Twilight Sparkle soon finds out that the storm isn't Rainbow's only problem. She's suffering from a very personal pegasus problem and Twilight has taken it upon herself to look after her friend during this delicate time.

Twilight Sparkle is a normal pony.

As normal as a pony can get as Princess Celestia's personal protogé, The Element of Magic and being the Savior of Equestria twice over that is.

She lives in Ponyville and is the librarian of Golden Oaks Library, she is the best of friends with five of the greatest mares in Equestria.

She is not some extremely powerful unicorn who has to closely monitor how much magic she has so as not to destroy anything by accident, she is not somepony who has infinite arcane knowledge at her disposal.

And she most certainly does not have Runes covering her entire body from horn to hoof.

This idea just randomly popped into my head when I saw the cover art, I have gotten permission to use it so YAY FOR ME~!
Tell me what you think of it! =^~^=

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!

On a request from Princess Celestia, Twilight Sparkle and the rest of the mane six explore an abandoned mansion located deep in the woods. While doing so, they unwittingly stumble across an enchanted mirror that scrambles their DNA and pops out three brand new bouncing baby ponies. Hilarity and drama ensue as the mane six must cope with being suddenly thrust into motherhood, as well as protect their new foals from a dark god that wishes to use them for his own sinister gain.

Celestia wants Twilight and her friends to loosen up a little bit around her. Luna just wants to try the hard cider. During a surprise visit to Sweet Apple Acres at the tail end of cider season, Princess Luna has just a bit too much to drink, and when she makes a rather inappropriate joke, Twilight comes to the very uncomfortable realization that she has never seen Celestia excuse herself to use the restroom.

EDIT: First and probably only ever, added Author's Notes to address the frequent "Were means man" issue. Please read them before commenting.

"Fluttershy gets bitten by a werewolf from the Everfree Forest, but when a side effect of the changes limits her inhibitions, she starts to wonder if the cure is such a good idea. Even if she does start to behave a little 'differently' otherwise..."

A one-shot story in the spirit and style of an episode of the show itself.

I have always been alone in this forest. I have always feasted in this forest. I call this forest home and those ponies that travel through it are my prey. I devour all those who fear me, all who come to face me. They fear me for I am Fear incarnate. But now...I have met one who does not fear...and I am unsure of what do with her...

Commander Shepard has been through a lot, but now that the Reaper War's over he can finally relax and take a little R&R, right? Soak up the sun, grab a few drinks, spend some quality time with Tali, introduce a new race to the galaxy... wait, what?

In the aftermath of the war, a new species has been discovered amidst the destruction and fire. A species that have access to powers never seen before, powers which could prove vital to the continuation of galactic survival.

The Citadel Council has elected to send Shepard, along with the rest of the crew of the Normandy, to introduce Equestria to the universe outside of their solar system.

Now Shepard must wade through obstructive bureaucrats, antagonistic journalists, and the odd, angry prince in order to bring Equestria into a new age of space and adventure.

So settle in, it's going to be one hell of a vacation!
