The author Alan Wake is one who has defeated this Dark Presence, but to save his wife and his world Alan had to remain trapped in the darkness.

Now, through his struggles to return to his wife, Alan has unintentionally released the Darkness and an old villain upon Equestria.

Can the unicorn find the strength to face the darkness, or is all of Equestria doomed to be the victim in the dreadful horror story?

REWRITTEN IN 2018! WOO!
Equestria Daily
Here's the music a friend made for the book based on how he felt when reading it.
Da semi-sequel be here.

Ignore the first story with his name. It is just what passed through his mind one day. This is his true appearance.

The Psychopath is a stallion with an unknown relation to the princesses, and yet he is held within the lowest levels of the Canterlot castle dungeons. He is completely chained up in his dark and dry cell, only ever thinking about his next prank and humming tunes that come from nowhere. His existence has been kept secret for centuries, and only the council and a few select guards know of him. Now, another mare will know of his existence. Twilight Sparkle will free him inadvertently, causing the psychotic pony with a strange appearance to float about Equestria, causing mayhem and destruction in the form of "pranks". How will the student deal with somepony who is apparently not trying to cause harm but does so anyway?

The image was made by Stalin the Stallion . Thank him for giving about thirty minutes of his life to draw that. (How did he even do that in half an hour?)
Proof-reader and aid for rewrite: Majora and masks. (Obsolete)
Proofreader: Twilight Scratch. Spank you very much for helping me. (Obsolete due to rewrite but they did help in the past)

This is set in the same universe as "The true Psychopath". It will not feature The Psychopath directly.
Personal tags: Creepy, Mysterious.

One day, as Luna is sleeping, she receives a message in her sleep from entities even higher than her and Celestia. Even higher than Father Time and Death! These two entities warn her of an imposing doom to the whole world as she knows it. If she does not hurry up, then there could be a catastrophe brought about quite soon, one that even Psycho would not be able to prevent or repair with the Illogic as all energies and powers stem from that which the Doomsday creature comes from.

This time, however, only Luna knows, and this "pony" is going to a new land, one that is much bigger and packed than Ponyville. It will be up to Luna and two unlikely friends, a stallion and a diamond dog, to stop this harbringer of doom. But...is it really a pony, or is there something hidden deeper than we know? There's also a red and white hidden in plain sight, but who will learn the existence of this delight? And will the diamond dog stop fumbling through the trash? Only time will tell.

Having escaped from the terrible Rainbow Factory, H8 Seed finds a new friend, and tells him about all the horrors of this place. With him, former worker persuades the main pony in Cloudsdale to go to war against the factory, as all this is must be stopped.
After the victory, when everyone thought that Cloudsdale is not in danger, H8 Seed finds Glaze under the wreckage of his Rainbow Factory. Learning that Glaze is alive, H8 Seed decided to help him.
Passes many months and Glaze finally gets better and becomes a real friend to H8 Seed. But will be able Glaze stay in Cloudsdale, if already all ponies in Equestria know about his bloody actions and watching him from the darkness?

This story is a sequel to Past Sins

Hearth's Warming is a time for friends and family to come together, celebrate harmony, and welcome the new year. Nyx is looking forward to just this as she rides the train to Canterlot with Spike and Twilight. She's going to meet her extended family for the first time and wants nothing more than to make a good impression. Yet, the sheen of the holidays can't hide the trouble caused by meddling grandparents, relentless reporters, and a paranoid uncle.

When facing Twilight Sparkle, Nightmare Moon was given a choice: redemption or revenge. What if she had chosen the latter? A grim fate awaits Equestria, but in a time of greater strife and conflict, Discord's return is accelerated. While he expected to bring chaos, he did not anticipate that he would end the Longest Night and bring hope and joy back to the land.

Discord struggles to reconcile his nature with his desire for admiration. While Twilight's friends strive to carve a new life in the ever-shifting Equestria, she searches for Celestia, the only one who can bring harmony back to her lands. But Nightmare Moon also seeks her sister in a desperate attempt to find her place in the world. New dangers lurk in the wild and more threaten to fall over Equestria. Nightmare Moon's decision broke the balance of the world. Will Equestria ever turn to peace, or will the spiral of chaos and destruction be the end of everything?

(An alternate history, this story takes the universe established by the canon and explores one possible outcome if Princess Luna had not been redeemed.)

This story is a sequel to Past Sins

Side-story to Past Sins - Spike almost lost Twilight to a hangmare's noose, but now Twilight is safe and Nyx is a filly again. Normal life is returning. Still, Spike can't ignore the fact that Nyx just isn't the same as he remembers her. Her temper is more volatile, and, when she gets angry, all he can see is the rage-driven Nightmare Moon of legend.

And thus Spike has to wonder: Is Nyx truly reformed, or is she one bad tantrum away from calling herself Nightmare Moon again?

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?
