This story is Light-dark in that there are only dark tones in the story. It is not grimdark.
Milk Spot and Verdure Patch are both unicorns that live on Secantor Island: A place with advanced steam technology where many a pony, griffin, and minotaur live. The island is completely covered in buildings that rise higher and higher, but not much goes well for those living lower and lower.

It might be impossible, and the tensions between Secantor Island and Equestria might end up sparking a war, but two unicorns will have to work together to escape this place and see if 'Equestria' is real or just a legend created by those who watch over everything in this dark world.

This is a collab between David Silver and I.

This story is a sequel to CUTIE MARK CRUSADER NECROMANCERS, YAY!

After losing their lives in a blood sacrifice, Diamond Tiara and Silver Spoon find themselves in Hell. They're not happy and they're letting every demon around them know it.

As luck would have it there just might be a way or two for them to get back home.

Follow these two ponies as they travel across the afterlife, trying to figure out how to return to Ponyville... And maybe get a little revenge while they're at it.

Diamond Tiara and Silver Spoon are banished to another world entirely, where they will have to use their wits to survive. With no money and no support, what are they to do? At least Pinkie Pie's on the way! Ponyfinder/MLP Crossover

Based on the events of The Apple Falls Far From the Tree but not requiring reading it to get right into things, as the characters involved have as little clue as you might as to why things are happening, they just are, and must deal with it.

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.

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?

A story of Slendermane, a slenderpony as he awakes, devoid of reason or purpose which hastily leads to a chance meeting with a young miss.

"Go to Sleep" Those are usually the last words anyone would here if they awoke in the dead of night to see Jeff the Killer, his bloodied knife dangling above their neck.
One night, however, could very well be his downfall when he breaks into the home of a Brony...

Warning: This is a fail / one shot short story off a random idea that will make little or no sense whatsoever. Read at your own risk.

Note: I could have used Jeff's actual photo, but I'm too much of a pansy to even look at it, so I found this Twilight alternative from Creepypasta.

Link has done many things in his life all at a very young age. He defeated hordes of monsters, traveled through time and into another world, and defeated two beings with powers equal to gods. Yet throughout all this he never lived a normal life.

While on a search for a friend who had left him long ago he is sucked in by a portal and teleported into the land of Equestria. When he awakens in this new land all of his memories of his life are gone. When the Elements of Harmony realize that he has no where to go one volunteers to take care of him until he can remember who he is.

The elements aren't the only ones who will try and get his memory back. They will get help from both a mystical being with wings and the dead to help the hero remember who he was. They better be quick though a evil unlike any other Equestria has ever seen is rising. And it wants the dead body of Link and it will do whatever it takes to make sure it happens.
