Twilight reads about a way to view a pony's soul, to see everything about them laid bare. When she tries it on her friends, will she be able to look at them the same way again? Or will the secrets hidden in their hearts drive her away?

(Yes, I borrowed the idea of a "soulgaze" from The Dresden Files, because it's something that really fascinates me. It's not a crossover, just an idea.)

Now has a sequel!

Keen Observation, a unicorn scientist and professor at the University of Canterlot, receives a strange delivery from a caravan of traders. A creature whose very bones were created by ancient spirits of evil, in the times before the coming of the Two Sisters, before the founding of Equestria. A creature known as a Husked Stallion. These are his notes, recovered by the Solar guard Acute Senses and overviewed by the protege of the Princess Celestia, Twilight Sparkle.

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?

In his lonely observatory on the edge of Ponyville, Orion discovers something its creators thought would never be seen again.

In an Equestria where Discord never was, and the Pony Princesses never came to power, a young Twilight Sparkle loses her family in a crowd during the Summer Sun Celebration. Little does she know that her very existence is about to set a series of events into motion that will take her far beyond the borders of Equestria itself—and change the fates of both her nation and her life, forever.

We all know that happy, somewhat silly mare, Derpy. We always see her when she's smiling and in a good mood, but what if that was just a mask to cover up her true feelings? What if the ponies turn against her due to her clumsiness and cross-eyedness? Will they push her to the brink of suicide or will her loyal friends help her with her life? What kind of impact will this have on her children: Dinky and Sparkler? This is story about Derpy's depression.

It's not that sad, but it does have a kind of depressing feeling.
