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?

Nightmare Moon has won, and the world has been shrouded in eternal night. But hope still lives. The land of Equestria is currently divided between the armies of the usurper and those of the Dawn Militia. However, the greatest danger to the rebellion may not be the dreaded Mare of the Moon, but her lieutenant, Eclipse–formerly known as Twilight Sparkle.

Twilight ventures out into the mountains to see a once-in-a-lifetime event. Disappointed by her friends not coming with her, Twilight crosses paths with a kindred spirit.

Update: The story is edited into a proper read without many of the horrors I originally put into it. Enjoy the ride!

Deciding he could be given another chance, Luna and Celestia come to an agreement to release the Chaotic God from his rocky imprisonment, locking his powers with a powerful spell. Magicless and with a chance at redemption, Discord's ways seem less chaotic than ever.

He does cause a lot of chaos though, to the faithful student of Celestia, who had eagerly taken over the task of watching over and teaching Discord by giving him a home under her own roof, in the process hoping to learn more about his species, powers and motives but surprisingly learning much more about both himself and her head... Which puts her in pretty amusing situations most of the time.

An adventure of a silly one sided (???) love and a look into the heart of Twilight Sparkle.

Pony Joe awakens before the dawn each morning, readies himself for his day, and then walks through Canterlot's cold and silent streets to his doughnut shop.

Life has become pretty mundane for Joe, but as he serves his customers and chats with his regulars he realizes that he has come to rely on that repetition...he relies on it to keep from remembering.

As a casual utterance by a new customer sends Joe into a spiral of haunting memories we learn about his life...and what he must give up if he wishes to move beyond his past.

Many years after sending her beloved protege to Ponyville, unease sits heavily on Princess Celestia's heart as her relationship with Twilight Sparkle seems to have cooled despite all they've accomplished together. On the advice of her sister, Celestia sets out to investigate and resolve the lost connection with her most faithful student. What does it mean to be a Faithful Student...or a Princess of the Sun?
