This story is a sequel to Serotonin

Sunset Shimmer has a coping mechanism, and Twilight Sparkle wants to talk about it.

This is going to be a disaster.

Thanks to Scampy for being an excellent prereader and source of inspiration.

Sunset Shimmer is in her apartment, alone, because it’s for the best. That’s why it’s good that she didn’t go to that party. It’s good that no-one knows what she does to herself.

But it’s fine. She knows what she’s doing.

She knows that she deserves this.

When your life is as dull a gray as the world that surrounds you, the mundanities can make it all seem meaningless. Sometimes all we need is a little color -- or six -- to reintroduce us to what truly makes life worth living.

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?

Losing her friends was the start of a self-destructive spiral for Sunset Shimmer. Convinced that she will never escape the echoes of her past, she tries to take her own life.

The attempt leaves her severely injured and she falls unconscious. In her dreams, she is visited by Princess Luna. They have much to discuss, whether Sunset likes it or not.

Twilight Sparkle is the master of her own mind. She is the Princess of Friendship. She is the fourth piece of the Alicorn Tetrarchy. She has incredible power, and she has always asserted it in a necessary and compassionate way. She has a charmed life—a wonderful set of friends, a beautiful castle in a lovely little town, and is constantly busy with her life, stretching her wings upward and outward to new horizons as often as possible.

There can be nothing wrong with her.

This story is a sequel to NOW YOU BUCKED UP.

When a new, strange kingdom of magic is discovered to the far west of Equestria, the Royal Sisters take an entourage and investigate. Which nearly sparks ANOTHER international incident.

Once again, they don't bring Twilight. And ONCE AGAIN, she's left to clean up the mess. Which involves yet another very long letter.

Twilight Sparkle gathers her friends after receiving a rather distressing letter from her mentor, Princess Celestia. She's not happy about the contents, at all.

It seems her friends all went on some magical adventure without her. And now they're all in a lot of trouble.
