The Nightmare. They thought they'd destroyed her with their little 'ray of harmony'.
They were delusional if they believed that.
She'd never be truly defeated - only delayed until she found her next victim. Luna had been weak, despite her title of princess. But now she'd found someone much better for the job.

Twilight Sparkle.

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?

The impossible has happened, through all the pain and darkness, Twilight Sparkle succeeded in her impossible mission...mostly. King Sombra is still plenty rough around the edges, but despite being an old dog he's making an effort to learn new tricks. Where will this new way of life take him? He has absolutely no idea, but with his queen to guide him, what could possibly go wrong?

This story is a sequel to Monsters

You might think that Equestrian nights are but serene exhibitions of Luna's work on the sky. You may believe that you can just lay out on the grass and admire the beautiful stars as a warm evening breeze caresses your mane. And you would be wrong.

Equestria is a magical place, and where there is magic, there is chaos. Dead rising from their graves, inanimate objects coming to life, strange apparitions making your foal cry in her room... sounds familiar? No? Then I'm doing my job right.

I'm Twilight Sparkle, and I work the Night Shift.

This follows canon up to the end of season 2.

After the defeat of Tirek, Equestria is safe once more, but Luna can sense that her sister is troubled. When Celestia retreats to the starry realm of ascension in order to look upon the past, Luna joins her to discover what is bothering her.

There is now a Spanish translation of this story, courtesy of Spaniard Kiwi

After an accident, Rarity and Twilight are thrown in a race against time to stop their transformation into changelings before they become part of Chrysalis' swarm forever.

The residents of Ponyville are unaccustomed to violence, but recent attacks are shaking up the normally peaceful town. On top of this, Twilight Sparkle has been experiencing short bouts of memory loss and is getting concerned with her own health. The truth in the situation may be harder to bear, however.

After King Sombra's defeat and the return of the Crystal Empire, Princess Celestia came to the mane six with an offer: to become a manifestation of her will throughout the world, an elite team designed to solve Equestria's most dangerous problems. Warriors and diplomats, Twilight and her friends must leave their homes and their loved ones to ensure the safety of all. This pursuit will push them to new heights, and new depths.

The world is a dangerous place.

When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?
