My name is Sombra Lucent. I am a resident of the Crystal Kingdom, hailing from the upper class sector. I am making this journal entry to archive my recent magical studies of artifacts and our history.
For as long as our people can remember, our kingdom has been the heart of Equestria. We keep balance and harmony across the land, and take great pride in our duty. Our love is their love, say they say.
But I want to find the source of all of this. I want to discover why the Crystal chose us in this otherwise desolate tundra of cold and ice, and what effects it may have on the kingdom itself. All of this exposure to the crystal has given our coats a glorious shine, and we as the shining guardians of Equestria have been aptly named 'Crystal Ponies'. But while our role in this world is strong, we are also quite fragile in mind and in body.
I have left the kingdom, braving the snow and ice to locate answers to our past and the origins of the crystal. I also hope to find some way to improve my magic and perhaps bring new ideas and studies to what I consider an otherwise crumbling society. They need a leader, they need to stop with their dreams of a crystal princess because in all this time of waiting and legend, there has never been one present among us. She is just a bed-time story for foals at this point, and I refuse to accept the praise and reliance on something that simply isn't there.

As Discord finds himself in the darkness of his own mind, Celestia visits him momentarily to leave the creature with a memory of when the two were children.

Discord managed to free himself from his stone prison, but some difficulties occured and gave him a new perspective as a pony. How will he adapt to these changes? And will his plan work this time?

Comments are filled with spoilers.

Princess Cadance noticed how lonely Princess Celestia seemed on Hearts and Hooves Day.

She decided to send a small love spell her way, as motivation to help her find a special somepony, even if it's just for a day.

Cadance immediately regretted it upon finding out who it was.

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?

This story is a sequel to Windfall

A brilliant mind discovers a problem in search of a solution, which leads to inspiration, which leads to invention, which leads to a technological/magical advance that will in time forever change Equestria.

Sequel to Windfall, set three years after the events in that story.

In a moment of weakness, Chrysalis had more than a taste of Shining Armour's love. 11 months later, Twilight Sparkle finds herself a brand new niece by way of 'A small foal in a basket on my door step'.

Discord is accidentally awakened once again from his stone imprisonment. He decides that the only true way to spread chaos throughout Equestria is to turn the Princess of the Night against the Princess of the Day. He succeeds in turning Luna evil once again and a massive battle ensues. Could this be the end of Equestria?

The Following takes place after Pinknesia: The Darker Descent.

Canterlot has been saved...The Entity defeated...and the lives of many restored. Celestia raises the sun...Luna raises the moon, and for once in six years in an age of blood and misery...Canterlot and Ponyville knows a peace that hasn't been seen for years and years. Quill and Twilight are set to be married, and Applejack is still trying to find the courage to tell Rainbow how she really feels.

But what about dear Scootaloo...a mare, grown now, in her own right? What does she...a year after succumbing and returning from death, have to say about Pinkie Pie, her mother who is believed to be dead? No body, no proof, no forgiveness. Under her smile, under her eyes, under her coat...a darkness emanates. Anger...and Despair, rocking her to her very soul. She is hell bent on finding Pinkie Pie, and NOTHING will stand in her way. What lengths will she go to, to find the mother she loves, and bring her home? Nopony knows...come now, watch...and listen...as we witness The Darkest Descent of them all...of a mare named Scootaloo.

Granny Smith has had a pretty remarkable life of adventure and excitement, but she settled down when she had a daughter. It wasn't long before she was blessed with another. So, how did she get to where she is now? How did Big Macintosh get so quiet? How did Applejack get so invested in the family business? What ever happened to their parents? Lots of questions, and lots of answers.
