Sequel: Left Behind: Sunny Disposition
Apparently it was scouted and is on EqD too

Nightmare Moon was meant to be released after a thousand years. A momentous occasion for her but terrifying for all the ponies on her day of freedom. She would get revenge on her sister and cover the world in darkness and shape everything to fit it.

That was the plan, at least. Instead, something went awry with the spell and she wasn't released when she was supposed to be. The mare-in-the-moon is brought into a world with stagnated technology, giant cities, and no sign of her sister or any of the other immortals. In fact, ponies don't seem terrified of her at all, and the stay within the core of her powers infused and changed the alicorn's body drastically.

The alicorn had no obstacles left! But...she was also a relic of the past. A past everyone seemed to have forgotten. A past she could no longer look upon.

Big thanks to Kryostase for helping spot errors I've missed.

A suit of armour wakes up in the woods from a very long nap and has some issues. These involve some less than stable quadrupeds called ponies and one very specific one which we shall refer to as Luna.

This story is a sequel to Sunspots

This story continues directly after Sunspots and contains spoilers for that story and Timeless.

When a mysterious group attacks a chemical lab, there was only one pony who Celestia and Luna knew could survive the ensuing challenge that lurked beneath earth and concrete.

Called into action against a threat that seeks to destroy both him and his new friends, Toxic Shield is pulled into the remnants of a conflict that all thought was burned away by the wrath of a Solar Empress. Many remember him as the pony with an odd voice, others, as the sole survivor of the Oakbark incident. Many call him the Iceberg. Cold, unfeeling, and without empathy, immune to both chemical agents and emotions it would seem. Very few care to explore the truth of such stories, at least until a gryphoness befriends the odd stallion.

And as a poison in many shapes and forms seeks to spread across Equestria, a reformed Windigo and Shadow Pony from the Limbo realm struggle to find their place in a world that once loathed everything they represented.
Many still do.

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 her successful attempt to stop Twilight Sparkle, Sunset Shimmer ends up in the universe of The Batman. Now, with the help of her mentor Zatanna Zatara and two best friends—Barbara Gordon and Pamela Isley—she has to figure out her place in a brand new world.

This story is a sequel to Rot

After the events in 'Rot', Twilight Sparkle has finally come to terms with her new self. Can she control her new powers? Can she ever have anything close to a 'normal' life again? And what happens when Discord's past mistakes come home to pass judgement on the 'new' Princess of Friendship?

Chrysalis is sick of Twilight always getting in the way of her plans. So sick of it, in fact, that she's willing to do anything in her power to stop Twilight from stopping her. She'll even go so far as to fall in love with her greatest foe.

Earth, the year is 2065. After a wave monsters from space invaded in what has been dubbed the "First Incursion", the world created a organization to stop these vile creatures called S. M. I. L. E. (Space Monster Interception League of Earth). To train the next generation of defenders, SMILE Academy was created, and it is here that they will be imparted with the knowledge and skill to fend off any hostile threat. However, an evil has set its sights on Earth, and wishes to initiate a Second Incursion.

But all hope is not lost, for one student, Sunset Shimmer, has the power to repel this extraterrestrial threat. Using her otherworldly device, the StaRaizer, Sunset will set out on her journey as Ultrawoman Aster! Now, if only she could remember how and why she has this power...

A story of discovery, of battle, friendship, and possibly love? It's time for the universe's newest Ultra Warrior to take the stage!

For so long Luna wanted her ponies to appreciate her work, the labor she endures every night to ensure their protection. But her compliments have come hollow and the nights stale with no ponies to flourish under her moon. She turned to a mysterious stone to wake the masses to their senses, but instead, she was banished, by her elder sister no less. She was left alone for centuries to face a slow and unanticipated demise.

Only centuries later, night by night, did a mare wished upon her moon. Countless times she hoped for it to grant just a single wish. A wish she felt not strong enough attain on her own. In one fateful night, the mysterious stone reciprocates her desire.

Clover the Clever never asked for his life to get so complicated.  It was bad enough tricking a drunk Imperatrix Celestia, war goddess of the Three Tribes, out of her accidental coup against Queen Platinum.  But now the most dangerous pony in Equestria has returned to trade her claim on the sun for a chance to woo him.

On top of that, his erstwhile mentor Star Swirl the Bearded has saddled him with a mysterious magical necklace and a uniquely bleak and pointless prophecy: If he's brave enough, and if he's clever enough, he just might survive Celestia for long enough to break her heart.

Now with an audio reading by ScarlettBlade!

Recommended by PresentPerfect! "horizon gave me the story I needed rather than the one I wanted ... along the way we get some very strong lessons about love, and meditations on the value of a lifetime and what one pony can achieve on their own."
