Sombra never realized this would happen.
Usually a villain is suppose to be defeated, right?
So, why did he, well...win?
Even he was shocked to see the crystal heart in his hooves. Never in a thousand or so years did he think he would pull this off; that he would actually...win.
So, what will he do now? Just rule over everyone and enslave all of pony kind? Or Perhaps kill the princess and mind control that purple unicorn and her friends? Or maybe have some common sense and figure out just how he will deal with all of this in the long run? With all these questions, he knows one thing for sure.
This is going to be very awkward.

Princess Twilight has taken her place as the newest member of the royal family. After some time Discord becomes Twilights personal advisor and they are driving each other crazy. In more ways than one.

With their partnership comes many changes to Equestria and Twilights political power has started overshadowing the Royal Sisters.
This was Celestia's plan all along, but it doesn't stop there.

Princess Celestia: Goddess of the Sun, ruler of Equestria, beloved Princess of ponies. She is loved by all, and loves all in return. A calm and wise ruler, she sits on the throne in Canterlot, maintaining peace and harmony throughout the land.

What most don't know is that her past is much darker: She was once a commander of legions, a warrior and scientist of unmatched skill. Thousands of monsters and abominations fell to her forces, slain in the name of an old leader, one entombed within his own throne. Free of her old form, free of the powers of Chaos, she was cast into a new realm, in a new form, with a new lease on life.

She is the God Emperor, Eternal Ruler of Equestria and Lord of the Imperium of Man.

A take on Humans Acting Villainously: Celestia has won, the barrier and conversion bureaus have wiped away everything humanity had and was.
But uneasy rests the tyrant's crown.
The Newfoals remember legends of things that go bump in the night, and they have decided that now even Celestia must know and fear them too. That there are beings to give even Luna nightmares.
Celestia is merely a Princess, and he is the King.

Yeah! Featured 8/7/14, 8/11/14, 8/12/14, 8/14/14 and 8/21/16. Thank you all.

Creepy Crawly, a young crystal filly, is left an orphan after King Sombra's Time Skip spell sends her a thousand years forward... without her parents. Without prospective parents in the Crystal Empire, she decides to leave the city on her own... and ends up finding out that love, and families, can be found in the strangest places.

Warning: This story is intended to be heavy on the feels. Read at your own risk.

Rainbow Dash, best pony, fastest flier in Equestria, all around awesome mare, was called upon to help with the wedding of her friend's big brother. And hey, she never leaves her friends hanging! Of course, when it turned out some kind of bug thing had replaced the bride, Rainbow was more then ready to fight. Heck, even after it seemed all hope was lost, the pegasus refused to give up.

So when she saw Shining Armor charge up a final spell, she smirked.

But when that spell reached her and flung her against the wall, her smirk devolved into shock...

Who was I...
It doesn't matter. The mind was willing, but the flesh was weak.
And the Kraahkan... it changed me. Told me how to accomplish my goals... turned my weak flesh into strong, hard steel and antidermis.

I am Teridax, the Shadow of Equestria. Or, as the guards of Tartarus know me, Prisoner 0.

And I've served my sentence.

Everypony must live with their choices. In Twilight's case, she must live with it forever, literally. Becoming Princess of the Afterlife, of Tartarus, however, was just half for atonement. She had another agenda. She wished to seek out the departed souls of her friends, to beg their forgiveness, just one last time. 10 years have passed and her search is still fruitless.

Now on the 10th anniversary of her friends' passing the true nature of their sacrifice is revealed. She is given the chance to make the choice once again. This time, will she choose Equestria or her dear friends?

So I was relaxing in my room, replaying my oldest, yet still loved trilogy adventure: Baldur's Gate.
I'd passed the first book and was working on the second, and had just changed my Thief main character into an Assassin and input all the changes on the character screen, when, well, it happened.
Nobody told me my laptop was an interdimensional portal, and I suspect that normally, it wasn't. I also suspect that normally, it would have no power to change me into my main character either.
Who I was before is unimportant now. Who I am now is Marketh Shadeblade.
And I will do what I have to in order to survive, or more importantly, carve out a little niche for myself here in pastel pony land.
There might be one or two small problems with that, but it's nothing I won't be able to handle. Right?

Red Team had been given an assignment. It wasn't the usual sort of assignment. They were assigned to defend their base 'until further notice'...and then never received notice. All announcements sounded pre-recorded, and enemy assaults were few and far between. The enforced inactivity was slowly fraying the bonds of the team...

...until something unexpected arrived. A tiny creature appears one day in their fortress, in need of compassion and care. Somehow, she finds that in this group of strange individuals, as she becomes their baby.
