Princess Twilight Sparkle has been faced with a difficult decision. Unsure of what to do, she seeks advice from her old mentor, Celestia. The ex-ruler of Equestria may not have an answer for her, but she does have a story. A story about guilt. A story about the greater good.

A story about the day after the worst day of her life.

This story is a sequel to Canterlot Has Fallen

Time marches forward in Equestria, and yet the allure of "what if?" remains. Twilight wonders about the "what ifs" as she tries to guide Equestria to a bright and prosperous future. Cadance wonders about the "what ifs" as she sees her daughter growing.

The power of "what if" tempts once again, but are the little ponies really ready for the answers?

Celebrating the 10 year anniversary of Past Sins! Thank you all so much for letting me and my stories be part of the community!

This story is a sequel to Past Sins

When pursuing Starlight, Twilight and Spike experienced variances of Equestria, and saw how the river of time could have been different. Now, Starlight has moved in with Twilight, Nyx, and Spike and has begun her studies in friendship. To thank those who have helped her embrace friendship once more, Starlight has created an enchantment that allows the castle’s map table to let anyone glimpse other variances of reality.

The power to ask “what if,” can be a source of great amusement… but for some, the hypotheticals are haunting reminders of what could have been.

The name's Slate. Straight Slate, detective by trade. It's no easy job, tracking down changelings on the cold city streets, but I'm good at what I do. I've been doing this a long time, ever since the attempted invasion at the royal wedding. But these days... These days, things are different. Something's rotten in the city of Canterlot, and one way or another I intend to get to the bottom of it. Even if it kills me.

Note: Comments are likely to contain spoilers as the story progresses. If you're starting from the beginning, I recommend avoiding them until you've caught up to the chapters in question.

Thanks are due to many people for help and inspirations, both large and small.

This is the original version of the first story I've ever written, over the course of three months as a brand new writer in late 2014.

I'm including these chapters here as a record of how the story looked when it began. This was the prototype for what would, over many years, become Black Feather. The story has gone through multiple complete rewrites, but this was the initial version. Enjoy reading my clumsy first steps into the world of writing!

Note: I will make the chapters visible again after Black Feather is published to avoid spoilers.

Special thanks to onlyanorthernsong for encouraging me to write this and helping to envision Pen Stroke's Nyx as an adult.
Extra thanks to Pen Stroke for permission to write the adult version of his character Nyx.

In Equestrian heraldry, the Kite Shield is a symbol of protection and strength, and those ponies with a kite shield cutie mark are usually honor bound to bravely protect any sapient being who may need their aid, often at great risk to their own lives.

This is the story of two ponies with such cutie marks, and what these cutie marks reveal to the other.

One pony is a gallant and brave career soldier, who has devoted his entire life to protecting Equestria from all enemies foreign and domestic.

The other is the reincarnated form of one of Equestria's greatest villains, given a second chance, now honor bound to use her power to protect the ponies she cares about.

It is a year since the events of Winter Bells and great changes are afoot this Hearth's Warming, as a newborn alicorn prince binds Twilight’s family closer than ever. And a conversation about the similar marks on their hides will give Uncle and Niece a new and better understanding of each other, and of each other's place in Equestria's emerging future.

A unofficial fan made sequel to Past Sins.

Thanks of course to Pen Stroke who created Nyx and her Universe.

Super special thanks to my tireless Editor and main(and rather heroic) proofreader Recon777 and to awesome prereading duties by Nightmare Nyx. This story is only readable thanks to their efforts . All Mistakes remain my own.

This is a fic based on the Time Loop Files, the format of which was first codified by Innortal on fanfiction.net.
Here's a brief guide.
The basic idea is, one character (the Anchor, usually the main character of a fictional setting) is looping back to the very first moments of their parent series every time either they die or some kind of time limit expires. They of course end up monumentally stir crazy given enough time.
Eventually others start to loop as well.
The reset is not always perfect. Sometimes a loop's history will be different to the "prime" loop, or canonical plot.
"Crossover" or "Fusion" loops also occur, randomly. These can involve the home loopers having a guest, or the anchor for one universe spending time in another, or replacements of one character by another.
Vacation Loops are where the Anchor (or others) decide/s "buck it" and lets off steam by doing whatever comes to mind. There's little or no attempt to maintain the original timeline.

In addition, and particularly more recently, it should be known that this story has a collaborative element to it - people may submit loop ideas or loops, ideally at the Spacebattles thread (a link to the current version of which is on the Trope page), and they may become included.

There's two page image options, thanks to Filraen - the current page image has been edited by the original creator from this work of theirs.. The other one is here:

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.
