Contains fairly mild grim-dark. Inspiration taken from the Dark Souls games, but it's not strictly a crossover.
Chapters titled "Arc #: Chapter Name" are part of the main story. Chapters titled "Character: Chapter Name" are one-shots about other characters, set in the same world, and aren't necessary in order to follow the main story.

Princess Twilight Sparkle has died a hero, but no one knows why.

Between an ancient evil that had not even existed until she struck it down, a mysterious crystal ball that bears some unknown significance, and a set of cryptic notes and behaviors from the princess during her final days, the circumstances behind it all are murky at best and suspect at worst.

And the rabbit hole only grows deeper from there.

The Crystal Ball Trilogy is a series of stories which deal with time travel, parallel universes, and other manipulations of time and space. Feedback is the first story; it is succeeded by Substitute and Divergence.

Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

Has an ask blog to go with it: Ask Sparkle and Thorn.
Also has a TvTropes page: Split Second Tropes.

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?

Sometimes, bad things happen to good ponies. A year following a tragic incident, Twilight Sparkle returns to Ponyville to visit what she has been missing - her town, her memories, and most importantly, her friends. But will everything be as she remembers it?

This story has a sequel titled "In History, Maybe".

When Scootaloo moves to Ponyville, she meets a certain cyan pegasus who becomes her idol. Things go well until a pivotal event causes her hopes and dreams to come crashing down around her. Broken and betrayed, Scootaloo must learn to accept her reality and embrace her inner strength with the help of her father and two best friends.
