A romance story with Twilight and Trixie, based in a world where Twilight and Trixie are a couple, and get together in secret to go on dates.

Having been rejected, yet again, Trixie decides that drastic measures must be taken in order to gain entry to the Golden Oaks Library... and Twilight's heart. Fortunately for her, and the rest of Ponyville, she's stopped by someone who knows Twilight intimately. Against his better judgement, Spike agrees to help Trixie with her purple pony problem. But what does Spike know about wooing mares? Apparently a lot.

Rarity, Rainbow Dash, Applejack, Pinkie Pie, and Fluttershy were brought together by Twilight Sparkle and the magic of friendship and have had incredible experiences. But now they are trapped in a world they don't understand-Equestria. How will these five normal human girls deal with such dangers as dragons, minotaurs, parasprites, -and perhaps the most dangerous of them all,- themselves?

NON CANON with Season 4 and EQG 2.

King Sombra’s dark influence was obliterated by the Crystal Heart, and the villain is well and truly dead. But when he attempts to steal the afterlife of an innocent victim, a human spirit is left hurtling towards Equestria, where this unfortunate soul is revived into the only vessel available: the reconstituted body of King Sombra himself.

Thus, a cheerfully oblivious alien is crammed into the form of the most evil and malicious being Equestria has ever known. Not that Shining Armor and Cadence know this, of course. As far as they are concerned, the King is back and he’s lost his fricking mind.

Nightmare Moon always had a backup plan if she ever were defeated; she would slowly regenerate herself and regain her power. The problem is she never expected to come back as a defenseless filly, or to return directly in front of the princesses. As punishment for her past crimes, Luna has given her a sentence far worse than being sent to the moon again. Nightmare Moon must move in with Twilight and report to Luna on the magic of friendship. She's not very happy about it.

By the way I am not trying to rip off Past Sins in any way. Nyx is NOT in this story, this will go in a completely different direction.

On one of her regular hunts for gemstones, Rarity discovers a treasure trove beyond her wildest dreams... and the lavender-scaled dragon who collected it. Despite a rocky first meeting, Rarity and Greenfire soon find themselves drawn to each other more and more. But the question remains: How did a young dragon end up in the Everfree Forest all alone?

An alternate universe story that puts our favorite purple dragon and his beloved fashionista into a slightly different situation. Art used with permission from the wonderful ArtisteFish!

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?

The story of the newly promoted Admiral Twilight Sparkle, and her first command. A fusion fic with various science fiction series by David Weber, principally but not only the Honor Harrington books.

Queen Chrysalis and King Metamorphosis are two ruling changelings from two separate Hives, each one having a certain enmity toward one another due to events in their past. When they separately learn of the wedding between Princess Cadance and Shining Armor, they plan to ruin it by taking the places of the ponies to be wed. However, they are completely unaware of each other's involvement or intent.

With both putting on a deceptive act toward one another, what happens when the deceivers are unknowingly deceived themselves? And can Shining and Cadance, each believing they must save one another from a fake, be reunited, or will they fall prey to the entrapment of the changelings?

An alternate storyline to A Canterlot Wedding.

Dedicated to Victor Frost, for without his Colt Version of "This Day Aria", I might never have come up with this.

It has been this way since time and memorial. Although the line between what is good and evil is remarkably thin.

Sometimes there is more going on behind the scenes than what is told in the pages of time.
