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?

Equestria is a land of magic and harmony, a peaceful realm ruled by immortal and benevolent monarchs. At what cost is this possible?

Following the discovery of a strange and powerful device, Twilight Sparkle is whisked away to the edges of a land she thought she knew so well. Here, surrounded by ponies whose very existences have been kept secret, she must contend with vicious enemies, hostile allies, and the truth.

In the far reaches of Canterlot Castle, high above in the towers lived the archmage. Everypony knew her, yet few had met her.

Twilight Sparkle sighed, having teleported away another noble seeking favors before reaching the top of the stairs for the second time today. They never learned. As the archmage, she already dealt with political squabbles far too often without inviting them into her home. Aside from personal favors for Celestia, she did what was required of her position and then returned to seclusion and research.

The nobility grumbled that no archmage should be a commoner, and Twilight’s disrespect toward them proved it. Each and every time they were forced to bow to her, they hated what they saw: the position, the status, the deference.

Was she not powerful? Was she not great?

Twilight, now reading through dusty scrolls and long forgotten tales, wrote in her notes — notes gathering dust of their own. A brief thought flashed through her mind.

Am I not powerful? Am I not great?

And then Twilight picked up The Tale of the Royal Pony Sisters.

Defunct side stories told in Across the Boundary. They can still provide a little context, but when in doubt, the main story here is canon.

Steel Song is a lot of things. Earth pony. Uncle. Professional bodyguard.

Retired.

So when he receives a mysterious package from Princess Luna a few weeks after the changeling invasion, he's understandably apprehensive. More-so when he presents himself before the Royal Diarchs to find that not only do they desire him to come out of retirement, but to take command of a most unusual position...

A position that may have more significance than any of them suspect. Because strange thefts are occurring on the Equestrian Railway, thefts that nopony can explain. Thefts that may have far more sinister intentions than their seemingly innocent nature may convey.

Intentions sinister enough to shift the balance of power in Equestria forever.

I woke up in the hospital. I don’t recall how I got here. I don’t recognize the mare who says she’s family. I don’t even remember my own name.

So what kind of pony will I become?

This story is a sequel to Time Goes On

After reuniting with her best friend, Sunset Shimmer has decided to do the one thing that will ensure Twilight will never forget her again: move in with her.

Now it's a simple matter of reconnecting with the mare who stole her heart, learning the ropes of her new home, and continuing her study of magical artifacts... And, perhaps, making new friends as well. All while dealing with all the surprising perils that seem endemic to Ponyville. But none of that could possibly be a problem for a pony as great as Sunset Shimmer, right?

It's going to be a long year.

Ten years is a long time, so Sunset Shimmer thinks. Ten years since she was last a pony. Ten years since she started her life anew as a citizen of Canterlot City. Ten years since making a group of wonderful friends. Ten years of absence from Equestria.

She's perfectly fine with that absence continuing for many years to come.

Twilight Sparkle doesn't appreciate Sunset's reluctance to talk about the past. She's been studying the strange activities surrounding Shimmer since they were teenagers, and has only found further questions. But a murder with ties to Equestria gives Twilight the chance to learn the truth about magic. To stop a terrible enemy from rising again, they must both journey through the mirror. Enlightenment is at Twilight's fingertips.

She doesn't quite know what to think when she meets Princess Twilight Sparkle.

Written before Friendship Games was released.

It's getting embarrassing.

Scootaloo, pegasus extraordinare and honorary sister of the coolest Wonderbolt ever, is still unable to fly. She'd been told to wait a while and she'd grow out of it. She'd been told that her wings would get stronger if she just kept practicing. She'd been told that she was just a late bloomer.

Bull.

It's time Scootaloo finally flew. She's going to pull out all the stops, break all the rules, and try every strategy in order to achieve her lifelong dream. Not alone, though. She's going to need lots of help from her friends if she wants to do it without getting killed.

At long last, Scootaloo will fly!

Sequel to The Queen of Hearts.

With the Changeling Kingdom no longer struggling, Nymph sets her eyes on her toughest challenge yet: To have her sister Chrysalis forgiven and able to return home with her. Queen Nymph travels to Equestria and swears to make her family whole again, no matter what it takes.
