The reason why Princess Luna turned into Nightmare Moon has been alluded to, theorized, and dramatized. But all of the reasons why have been grandiose and very often external in nature. But all that is really needed to turn someone from a being of good to a being of darkness is but a simple whisper and time. A whisper given by a force of hatred and fear.

How did this happen. King Sombra has returned and taken over the Crystal Empire, the elements bearers are divided, and Equestria is at war. To understand the end we must start at the beginning, and it all started when Rainbow Dash preformed her first sonic rainboom.

Made the popular stories 9/3/16, 9/4/16, 9/5/16. Awesome! Three days straight.

King Sombra, the tyrant of Crystal Empire is back, only to be imprisoned by princesses and put through reformation with Twilight Sparkle as his teacher. Can somepony with heart as black as night be reformed? Twilight believes so. Sombra in other hoof isn't so sure but something in that mare makes him try.

This is going to be one of my longest stories this far. Marked Teen for sexual innuendo and slightly gory-ish scenes. Nothing too bad though. Also this will not be a story that deserves a dark marking.

For now I'd like to thank Alun Aleriksson, pony of change, Microshazm and Sidetrack for helping with the grammar and overall writing in general. Thank you so much.

After she escaped from a world where nightmare moon ruled equestria, she thought it was over. But nightmare had fallen in love with everyone's favorite purple alicorn, and nightmare is two things when it comes to her lovers, obsessive, and persistent. Lets see what happens when she follows her back, shall we?

Things aren’t right. Ever since the defeat of Nightmare Moon, Twilight Sparkle has been having visions of a life that is not hers. Or… that’s what she thinks. Secrets long buried are about to bite back, truths come to the light and a conspiracy unravels. After all, how is Twilight to accept that her real parents are ponies that history says are threats to the land.

Since Apple Bloom enrolled in dance class, she and Tender Taps have been spending a lot of time together. But when Scootaloo joins the class and proves to be a better dancer, and also becomes Tender Taps' new partner, dance class suddenly isn't so fun for Apple Bloom.

King Sombra was defeated and the Crystal Empire was saved, but not long after that, Twilight and her friends learn of a pony intent on resurrecting the fallen king. Princess Celestia and the crystal ponies identify him as Temor, the adopted son of King Sombra.

No one knows where Sombra found him or why he chose to raise him and adopt him as his heir. Now it is a race against the clock to stop Temor from completing his goal and in the meantime, the former prince reminisces on how he became who he is today.

This story is part of The Equestria Tales series, although set in an alternate universe. It is a what-if story based on a line from Possession in the Crystal Empire.

The story occurs in early season 3 and diverts a bit from season 3 and onward.

FEATURED!

"June, honey, be a dear--reschedule Luna and K.K. That's what I call Princess Celestia--what a hoot!"

K.K....K.K...K.K...

Ever since hearing this little tidbit from Spike, Princess Celestia has been wondering just why in the world Discord would call her K.K.? She could understand a pun about the sun or an insult using her actual name or even a mocking version of her royal title, but K.K.? What does the nickname mean?

Finally, Celestia decides to just ask Discord. Discord, however, realizing how curious she is, offers to tell her only in exchange for a little favor. After strong negotiations, Celestia agrees to his terms and finally founds out what K.K. means...and the answer makes her realize many things about her relationship with the chaos master and the magic of friendship.

While going to meet her new niece in the Crystal Empire, Twilight Sparkle discovered King Sombra's horn and nearly recovered essence in his study beneath the castle. Still weakened, he was captured and transported to the Canterlot dungeons.

Seeing an opportunity, Princess Celestia enlisted Twilight (the one who outwitted his traps and then discovered him) and Fluttershy (who reformed Discord) to try to bring out the good in Sombra.

However, just as they seem to be making some progress, things take a turn for the strange, as four ponies they had never seen before began fighting in the streets with Dark Magic. Four ponies with unusual coloring, yet who seem oddly familiar...

A mother will do a lot for her child, even give them up if it meant them having a safer life growing up, despite the obvious pain that comes for the parent.

That pain is something Queen Chrysalis has gone through for eighteen years, but now the time is upon them, and she wants her daughter back. Even if that means invading Canterlot during a royal wedding.
