Rainbow hears that Trixie is back in town, and that Twilight knows about it, but failed to tell her friends. Thinking something's up, she gets AJ to help her spy on Twilight, for her own good of course, and uses something she got from a purple unicorn stallion that had come to town a few days ago to help with the spying. Of course, things aren't way they seem with this, and the pair end up in more trouble than they expect, though hopefully not more than they can get out of.

After helping Spike and Rarity while the little dragon was cursed as a werepony, Princess Luna sets out to do all she can to help the other ponies that embodied the Elements of Harmony. On her journey, she finds friends she didn't realize she had and something more.

"Who are you?!"

Lyra wrenched her hands together, strands of teal hair falling over her golden eyes. Suddenly, she seemed so small. She didn't answer. Couldn't? It hurt to remember, hurt to say. She was lying, or maybe it was the truth, and she really didn't know.

Life is hard to deal with. Whether the problems are internal, or external, it's never easy. Finding a good outlet for your problems is a good way to reduce the stress of life, but when the outlet is another pony, with problems of her own, you may find your own problems taking an unwarranted backseat to theirs.

Silence. The golden rule is silence. Silence, and obediance.

For years, you have trained as a royal guard. Now, thanks to the fortuitous return of Shining Armour, your old-time friend and Captain, you are promoted to guarding Celestia personally. What follows, though, is the discovery of a personal side to the Sun Princess that you could never have imagined, not even in your most vivid dreams.

Discord is trapped in stone once again. But this time, he does some thinking. No, not about revenge, mind you. But about a certain lavender mare...

This story is a sequel to Past Sins

Side-story to Past Sins - Spike almost lost Twilight to a hangmare's noose, but now Twilight is safe and Nyx is a filly again. Normal life is returning. Still, Spike can't ignore the fact that Nyx just isn't the same as he remembers her. Her temper is more volatile, and, when she gets angry, all he can see is the rage-driven Nightmare Moon of legend.

And thus Spike has to wonder: Is Nyx truly reformed, or is she one bad tantrum away from calling herself Nightmare Moon again?

Dismayed after her loss to Chrysalis, Celestia departs the royal wedding reception early, retreating to her royal chambers to console herself with a bottle of wine. Concerned for her sister, Luna soon follows to check up on her...

(Rated Teen for tipsy princesses, and thanks to Junglepony for the cover art!)

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?
