Touch, Smell, Taste, Hearing, Sight

This is the order the five senses develop in for foals as they rest, cradled in the warm safety of a mother’s womb. But for one, her womb was a thorn bush in the dark of night. For one, the safety and warmth that should have carried her into the world was replaced with pain and cold.

These are Nyx's first hours.

Side-story to Past Sins - Slowly, the wounds inflicted by Nightmare Moon's reign heal. Ponyville is being reconstructed, and the last refugees are leaving the castle. Nyx is with Twilight. Celestia and Luna rule Equestria and guide the sun and moon once more. Everything is as it should be.

But some things are never washed away. These are the things that remain to remind us of the past. They remind us of the good times we've had with friends and family. They never let us forget the mistakes we've made. Everyone has them. Twilight has them. Nyx has them.

And, on occasion, when you share your scars, your photos, and your trinkets with another, they just might share theirs in return.

GLaDOS is free of Chell, free to continue testing, when she discovers a portal gun Wheatley tried to repair with duct tape. When the portal gun catastrophically fails, the enrichment center, GLaDOS, and Chell are literally dropped in the middle of Equestria. The mute test subject soon finds the world of ponies far more welcoming than the human world. But GLaDOS sees possibilities. Let the testing begin... for science.

Every time a unicorn and a pegasus have a foal together in Ponyville, Twilight Sparkle is under orders to be present for the birth. Most of the time, the pairing results in an Earth pony, but Princess Celestia knows that there's a slight chance something different, something SPECIAL will happen.

That day has finally come. A kind, loving couple has been blessed--or perhaps cursed--with an alicorn foal...

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?

After an accident that Rapidash has only a hazy memory of, she finds herself in the company of an odd blue Ponyta. With no clear way home she has to adjust to this new world and find her own way back.

Twilight and her five friends are transported during a botched spell, across dimensions to... Ponyville, Equestria? But not the same one that they knew. Sitting on a bench is Harpsy and Babar. The Doctoress avoids apples from an aspiring Applebuck. And in a library across town, six stallions join their forces as they try to decipher the appearance of filly look-alikes of themselves around Ponyville!

Arceus has been imprisoned for many millennia, and in that time he has watched his world fall apart. But once he is finally freed from his prison he decides that to protect his Pokémon, and his family, that he will move the Pokémon, and a few select 'humans' to a world where they might live in peace, Equestria. However, not everyone on this new world shares his view of peace and the very presence of the Pokémon upsests some of the citizens of the world, even some of the ones he brought with aren't too happy with the situation. But a god's will is a strong thing and without his willingness the Pokémon and the citizens of Equestria are going to have to learn to get along, or at least tolerate each other. And there's a slight problem with some of the humans too, well, former humans that is.

I also have a Tvtrope page that is kept somewhat up to date by Kingofsouls if you know how to Trope, and want to help set it up, go here Tvtrope Link.

Since a lot of people keep aking this I'm gonna put an explanation here. I'm not following any one canon-verse here, I'm making a hodge podge universe with bits from the Manga, Anime, Games, and Movies, as well as some etcetera concerning issues addressed in none of them to great lengths. (Arceus' power is far beyond what he has in the games or movie and this does contain some Pokephilia, which comes from pretty much no canon material ever.)

What would you do, if you met a pony who was at once your brother, and yet not? Applebuck wishes to reunite with his 'Cousin JayJay', and braves the dimensional divide to reach his goal. But being a small foal, how will he deal with a world in which everything is flipped? His friends, his family, and even... himself?
