This story is a sequel to Lost into Shadow

Twilight has failed, or rather, she has succeeded. Her darkness is her power, and together with her husband, Queen Twilight has a new plan for all of Equis.

The days of harmony are dead and gone, and all the world will be forced to mobilize against the might of the Nightmare Hordes. Will they prevail in the faces of Wrath and Despair? Do they have any hope of someday returning to a time of peace and love?

Not a chance, because in Chapter 1, Hope dies.

Twilight had reached her peak, she was at the happiest point in her young life. The day of her coronation as Equestria's newest princess had finally arrived. Then the unthinkable happened, Sombra appears in the throne room alive and well demanding his chance to be reformed by pony society. The unthinkable happens again, when his wish is granted, spearheaded by none other than Princess Twilight herself. Will Sombra's nefarious plans bring her to ruin, or will she succeed against all odds? Only time can tell as it reminds them both that plans have a way of changing all on their own.

Anon likes his life to be simple. He wakes up, goes to work and sometimes gets himself a good book to read while he is home. It's a routine that he likes to follow, it makes him feel like he has a bit of normality with his life in Equestria. The fact that having Celestia come crashing into his home as part of his routine should prove that his life is anything but normal.

In the aftermath of her battle against Tirek, Twilight Sparkle is unwell. She wants more. She needs more. And she is afraid of what others might think of her.

But even in the midst of her growing despair that she has betrayed everything she stood for, she learns something about friendship and what it means to be an alicorn.

Chrysalis invades Canterlot again, but this time she has something different in mind. Now Shining Armor must fight for Equestria... Over a friendly game of Starcraft 2 multiplayer. In this unending plight of trash talking, accusations of cheating and bizarre tactics, who will prevail?

Written in a fashion non-gamers should be able to understand.

(PEGI Rating T. Ratings may vary online.)

Princess Twilight Sparkle has done something unheard of: she's found a changeling right outside Canterlot borders! But much to his surprise, Twilight doesn't kill him or turn him in as the law requires. Instead, she saves his life.
And when life gives you lemons, you will feed.

Disillusioned by the tragic events on Panchaea, Adam Jensen chooses to subsequently end everything and hope that mankind will find a solution to the augmentation debate by itself. Instead of welcoming death however, he finds himself in a strange utopian world filled with pastel-colored ponies.

Unfortunately, this does not mean Adam is allowed any reprieve from morally challenging decisions.

A/N: Deus Ex: Equestria is written in a way that does not confuse people new to the lore too much but feels familiar with the players. This story will feature a vote at the end of several chapters that will affect the direction of the story based on Adam Jensen's actions in the world. It is divided into three categories: Combat, Stealth, and Diplomacy. Choose wisely, for it will have long-standing consequences.

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.
