Young Twilight is ecstatic about being enrolled in "Celestia's School for Gifted Unicorns". To show her excitement, she sends a letter to her mentor along with a drawn picture expressing her joy. Though, she was completely unaware that Celestia would delve deep into her work and search for meaning in it, while involuntarily causing herself great strife.

Another day, another skiing trip. Double Diamond now has the blessing of having a friend accompany him on his outings. On the other hoof, he finds it strange that Party Favor goes with him more often than Sugar Belle or Night Glider. Something is up with the balloon-making stallion. But what?

Perhaps a little advice from a local specialist might point him in the right direction.

NOTES
1. The story involves season 5 spoilers. Watch the first two episodes before reading this.
2. This is M/M fluff.
3. Double Favor for the win.
4. I'll add in the character tags if/when Double Diamond and Party Favor get any.
5. Made the Popular Stories list.

This story is a sequel to Stallions of Harmony - Longest Night

Life wasn't easy for Thunderlane. Since losing his parents, his life was reduced to work, caring for his little brother, work, dealing with Rainbow Dash, work, his questionable relationship with Blossomforth, work and even more Rainbow Dash. Not even Nightmare Moon's Everlasting Night changed that.

Just when it seemed like it won't end, his life was hit by a certain Lightning...

Other tag stands for Blossomforth (who has no tag), Cloud Kicker and Raindrops (who both have, but there's a limit).

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?
