When a number of strange incidents occur around Ponyville, all signs are pointing to two ponies at the center of it all. Will the farmmare of Sweet Apple Acres and the town's fashionista ever explain why they've been spotted together in the strangest of scenarios?

Note: The Twilight Sparkle represented in chapters 2 and 4 follows the events from my other fic, Magic's Dawn. Sorry about any confusion there. Working to remedy thr issue of multiple story knowledge for future fics following that plot.

While experimenting, Twilight's new teleportation spell goes awry, sending her careening into a different world, just in time to take part in a fantastic ritual called Heaven's Feel. Twilight must adapt to the world of humans and take part in the vicious conflict that is the 4th Holy Grail War as a Servant alongside her equally reluctant Master. The duo must contend with powerful adversaries and survive the subtle machinations of the Magi determined to win the Grail at any cost. Can Twilight overcome her unwillingness to take the lives of others? More importantly, should she? And is there any way for the displaced Unicorn to return home? Trapped, alone and in a different world and surrounded by enemies on all sides, does the Magic of Friendship still hold any hope for Twilight?

A crossover with Fate/Zero.

During the daily ritual to lower the sun to raise the moon, Princesses Celestia and Luna have their abilities locked. At the same time, a new, yet familiar, alicorn crashes into the throne room of the castle.

This is the second Friendship is Magic fic I've written, though I've tried some new things this time around. In my head, it does come after my first fic and my as-of-now unwritten second fic, though I think it can be stand-alone just fine. It doesn't really refer to the events of "The Party's Loyalty," and while it does make one offhand comment in regards to the second one I originally planned, I think it can be safely read without knowing much.

Instead of banishing Nightmare Moon, Celestia successfully separates Luna and the nightmare, and both then seal it in the moon, but the stain of both acts are too much for the Princesses and both perish, but not before giving the prophecy of their return. 1000 years later is a changed Equestria, a splintered government, no advanced school of magic, difficult weather patterns, and a looming threat from the Moon. Can the reborn Princesses be found in time? Is friendship still the best hope for a happy tomorrow? The more things change...

On the night of her return from exile Nightmare Moon comes across resistance as she had expected. However she had a backup plan on hoof for just such a predicament, tearing off a small fraction of her soul and attaching it to the bearer of the element of magic. Now she must play the long game to ensure that she can obtain the loyalty of her new host and once more rise to power over Equestria.

The path before her is set and she must now walk it alone. The sands of time continues ever onward, with everyone already trapped in its muddy depths. The sun will rise and the sun will fall. Waiting for its call, Death awaits for all.

I just put the two together

"Dear Celestia, what have i got myself into?" Twilight and Rainbow Dash have always had each others back, but now Dash has no choice but to put her life in Twilight's hooves. Due to one of Twilight's magical experiments gone wrong, Rainbow Dash has been changed back into a 3 year-old filly. Now Twilight has to find a way to to change her friend back before the effects become irreversible. But will Twilight's attitude go from 'mother' to 'lover'?

It is the thousandth year since Nightmare Moon's banishment and she has returned. When the battle with Nightmare Moon goes awry, Twilight's friends and family must cope with the destruction left in Nightmare's wake.

Note: This story is based off of the picture giuliabeck's You Are Mine and Sparkle No More.

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?
