This story is a sequel to The Calming Christmas Flame

Short micro-shot between The Calming Christmas Flame and its upcoming sequel. Happy Valentine's Day!

Twilight Sparkle is engaged to Sunset Shimmer. Thankfully, they get the Sparkle house to themselves, ensuring Sunset's antics don't lead to embarrassing "walk-in" scenarios. Even so, Twilight happens to "walk-in" on Sunset and her pajamas.

Sunset convinces Twilight to spend a Christmas with her and the girls in their world so she could get a taste of what it's like while accidentally showing her one of the best parts of the holiday.

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?

Twilight has always grown up close to Luna and Nightmare Moon, both whom are two sides of one coin. The Sun is but a myth most have forgotten and so are the elements. Life as far as Twilight is concerned couldn't be going any better, for there are only 2 whom she cares to hold dear. All until one fateful day in Luna's embrace she is asked to help end the darkness, by finding the elements and making some friends. Reluctantly Twilight agrees but only for Luna and no pony else. Setting off on her quest to help with the Lunar Celebration must she make friends, and find the elements all before it is to late.

(The first what if story in many to come, and since I can't post separate stories in the chapters, I will be posting them as separate what if one shots.)

While some of these what if stories seem like they could use a continuation, the idea is to put the thought into some ones head so that they can if they wish, pick it up and continue the story.

Nightmare Moon has won, and the world has been shrouded in eternal night. But hope still lives. The land of Equestria is currently divided between the armies of the usurper and those of the Dawn Militia. However, the greatest danger to the rebellion may not be the dreaded Mare of the Moon, but her lieutenant, Eclipse–formerly known as Twilight Sparkle.

(REWRITE IN PROGRESS)

After a weekend spent in Canterlot, Twilight Sparkle arrives home to find an odd scroll in her saddlebags. In the following days Twilight is plagued by terrifying nightmares, and horrific visions from a life not her own. Can Twilight Sparkle resist the Nightmare, or will she fall prey to the darkness?

Princess Luna's Lunar Stallions kidnap Twilight Sparkle when they see how lonely Luna is, and give her to the Princess as a gift. Nightmare Moon emerges from Princess Luna's psyche during the sleepover. The dark goddess would love nothing more than to have the beautiful mare all to herself, and the resulting chaos forces Celestia to call a psychologist to sort out Luna's multiple personalities.

This story is a sequel to Celestia's Tiny Student

(Title changed from "Ponyville's Tiny Librarian" for reason pointed in this blog )

Twilight Sparkle is a one-kilogram pony the size of a large rat, shrunken by Princess Celestia following her entrance exam to the Celestia’s School for Gifted Unicorns to ensure that her power surges would not pose a danger to the ponies around her.

She’s spent thirteen years full of hard training at her new size, facing the life-threatening experiences that came with living in a world of giants. To survive those thirteen years of hardship and joy, of learning and adventure, and of pride and humility, Twilight has challenged herself to be stronger, to overcome any obstacle.

Now that tiny Twilight is on her way to Ponyville to oversee the preparations for the Summer Sun Celebration, how well will this miniature mare fare outside of the confines of the castle? How will the other Element Bearers react to her? How will Nightmare Moon react to the tiny unicorn? Is Twiny prepared to face Ponyville, and, more importantly, is Ponyville prepared to face her?

The years have passed well for Twilight and Cadence: the Crystal Empire is prosperous, their ponies are happy, and their love is strong. All is well, until Twilight makes a discovery that threatens to destroy the life they've built together.

In Equestria, Princess Celestia struggles with feelings she thought conquered long ago as she is torn between anger at the past, guilt in the present, and hope for the future.
