It has been weeks since the defeat of the Dazzlings, and Sunset Shimmer's friendships have only gotten stronger. Whilst finally relaxing in the times of peace, Sunset discovers an old enemy: Sonata Dusk. Strangely alone and apparently homeless, Sonata's luck seems to be at its all time low.
Seeing a little of herself in the former siren, Sunset embarks on a mission to help Sonata find friendship.

A man stumbled into Equestria through means unknown. A year later Twilight Sparkle saw the worst his species had to offer and, in a paranoid fit, tried to have him killed.

Cast out by pony society, this man must find his place with the other Equestrian outcasts in order to survive. Fortunately, there are more of them than anypony else thought. And they aren't happy.

He may not like it, but he has little choice but to step into...

The Kingdom of Darkness.

Inspired by SaiyanUltima's "Seasons of Darkness".

Twilight invites Sunset to spend a night at her house. Late night, Twi decides to read a story to her friend, but it seems that Sun isn’t paying attention to the story. Why was she looking like that at Twilight?

Hi, my name is Ditzy Doo. Many of you know me as the author of the 'Wasteland Survival Guide'. For 200 years I wandered the Equestrian Wasteland, and through those experiences I gained the knowledge that I shared with everypony through the Guide. Now, it's time to tell my side of the story.

This is a story where the Achievement Hunters are teleported into equetria. This is my first story please go easy it on it and please tell me what I can do to improve my writing. Twilight will not be a princess in this because, to be honest, I do not like the idea of Twilight being a princess. Also coltcuddling is in this story. For those who do not like coltcuddling, a warning will be placed before it in the part of the story that will contain it.

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?
