After discovering that Cadence is not who she appears to be, Twilight is sent to another world entirely by the disguised Changeling Queen to avoid her plan being disrupted.
When Twilight lands, she discovers that not only have Spike, Owlowiscious and Peewee followed her, but that they've arrived in a world where the main sentient species is human.
There's still a place where they teach magic, though.
Crossover with Harry Potter. Twilight will be effectively taking the role of Hermione.

I've marked this story as cancelled to reflect the unlikelihood of it continuing. If I do come back to it I'll revert that.

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.

==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.

Blue Angel now has a TVTropes Page!

In a world where everypony's destiny is permanently emblazoned on their flank. Three young fillies seek the paths that belong to them. Little do they realize, the journey's destination is not always determined by the ones who walk it.

Gayle is a fitness nut. Steve is a professional layabout. Gayle is super motivated, Steve is super not. The two are an unlikely pair of roommates, a real life odd couple. While they're such opposites, they're also an unlikely pair of firm, if antagonistic, friends. They also share a special birthday...

So of course, things get interesting, as things are wont to do in stories. On their 25th birthdays, they start noticing... changes. Are those wings Gayle is sprouting, and is that a beak? Is Steve growing a horn on his head... but losing a "horn" somewhere else? Why do the names Gilda and Lazy Bones sound familiar? Time to get the hell out of Dodge! In their quest to find a safe haven they'll stumble across a certain pair of twin brothers and a whole motley crew of other Equestrian castaways in what might be the most bizarre road trip ever! Of all time! And is that love blooming between our intrepid heroes?

A side story in the Five Score, Divided by Four universe.

ALOT of swearing. So beware, if that sort of thing bothers you. Seriously, the main character swears like a pirate on shoreleave.

Book VI
A month has passed since the Invasion of Canterlot. In that time, Dusk and his friends have continued to live peacefully in Ponyville. Recent revelations have shaken them, but they stand firm, their friendship and love as strong as ever, if not stronger. They help each other, lend their strength and remain united by the magic they all share. The threat is defeated, as it always is.
But these threats are never truly gone. They wait, they fester, they grow... they rise. Now, they have risen once more. Growing shadows creeping from the North. Vows of vengeance rising from the Pits. Roars of rage echoing across the land. Once again, they must stand together and face them, strengthened by their ever-growing friendship.
But these ancient enemies aren't the only things that need to be contended with. Dusk and Twilight continue to explore their relationship, but what will it lead to? They know of Ray's terrible secret, but how will they ultimately cope? What are these whispers of Twilight's destiny between the Royal Sisters? Can their friendship withstand the trials they will soon face?
However dark the shadows may be, one thing that's certain is that there will always be a Ray of light shining in the Dusk.
Best cover ever by Quillin Words!

Book V
It seems like a perfect day for a wedding. With the sun shining its brightest in the sky, birds singing their ballads in the trees and emotions running high, nopony could even begin to argue with that assessment. When Dusk and his friends are called in to help with the preparations, it looks like it could be even better. A time for celebration and for merriment.
Yet all of this is calm before a storm and it will be a great one. Underneath all the cake and the flowers and a gowns, a threat looms over the kingdom. A threat of invasion, which will soon be realised on this happy day. Sparked by greed and hatred, Chrysalis and her hive are coming, their numbers great and their sights set on conquest. First, Canterlot, then all of Equestria.
When they descend, it is the Elements of Harmony who must rise to defend their home. Dusk must take up arms against those who would do them harm. But after the scars that still plague his mind, can he bring himself to hurt another being, even an enemy? Will he be able to take up the banner and stand up to the Changelings or will he succumb to his lingering fears? And why can't he shake the feeling there might be something more to this, that his lurking foes might be orchestrating this?
All that is known is that Equestria will soon darken for a warring Dusk.
Cover done once more by the irrepressible Quillin Words.

Book IV
Dusk used to think he was the most unimportant, useless pony that had ever lived. He didn't think that anypony would accept him and he would always be alone, save for one. How wrong he was. With the lord of chaos sealed away once again and his true destiny discovered, to say Dusk has come a long way from where he began would be an understatement.
Now he's the Seventh Element, new responsibilities as well as new opportunities have been opened up to him. An education, under one of the most powerful beings in Equestria has begun, allowing him to expand upon his magic, if he can handle it. At long last, he has taken his his friendship with Twilight to the next level, but that was only the first step. Now, they both must learn not only the magic of friendship, but of romance too.
But not everything is as perfect as it appears. Blackhole Doom may be gone, but his deeds and memories remain in Dusk's mind. Can he cope with the scars his darker self has left? Will he and his friends be able to confront them or will he keep them locked away? A story is told of a Fallen Soul, a fallen hero from time long past. But how much of it is actually a story and could it be something more?
With all of this, meeting new ponies, the good and the bad, new lessons to learn and new adventures to be had, it is true to say that Dusk... has finally dawned.
Cover again by the marvellous Quillin Words. Thanks!

Book I
Meet Dusk Noir, a unicorn stallion from Canterlot. He attends Princess Celestia's School for Gifted Unicorns, has a liking to learning and reading and has a unique magical talent. He seems like he would be happy, but there's just one problem: he doesn't have any friends. It's not that he doesn't want them, but he just feels that he wouldn't be worth the time of anypony. He sees himself as unremarkable, a waste of space and not much to bother with. There's only one pony he'd even consider being good enough as a friend for and he doesn't even know how to say the first word to her. It seems like he will always be alone.
Until one night, when he discovered by the Princess of the Sun and is sent to Ponyville to meet her at last. Can he achieve the goal of earning her friendship and much more besides or will he be simply left alone?
This is a story that I began as a sort of creativity outlet when I discovered how much of a fan I was of the series. From there, it just kind of grew and I enjoyed continuing it. Doubtless, you probably know what it's going to be about before you even read it and would even be tempted to point it out. I won't try and change what you think, all I ask is that you give it a chance.
There are two more stories following this, both of which along with the fuller version of this one, can be found on my fanfiction account. Just search my username and you'll find them, if you really want to read more that is. I'll try posting on as regular a basis as I can. That is, if it's received well.
This first one isn't my best, I'll admit that much, but I certainly did try my best with this one and what I had planned for it. I hope you enjoy it.
The cover was by Quillin Words and he did a fantastic job, thanks dude!
