Every day after lunch, her father would take her to someplace far away to teach her the secrets of chaos and magic.Usually, it was a fun, awesome place she had to promise not to tell Mother about but, this time, it was just a tree.

What was so special about a tree?

In the Pandoraverse, the library is still standing and there's no Friendship Castle.

Tell me if I should add some other tag

After his violent defeat, the former tyrant King Sombra has managed to claw his way back from the land of the dead and has returned to Equestria to seek revenge on Princess Celestia and the Elements of Harmony. However, the Emperor of Darkness is no fool. He knows that he cannot simply seek retribution on the Main Six or the Princess of Day, so he waits, gathering intel on his foes, learning of their weaknesses. When the time is right, he will strike. Can our heroes overcome King Sombra's plot for vengeance?

Sequel: The Return of the King

*Note: This story takes place in my official headcanon universe, not in the one for Shattering a Heart of Darkness

The real Nightmare Moon has returned during Nightmare Night, and she plans to get revenge on Twilight Sparkle. However, she hasn't been aware of any events past her demise. Or the secret feelings a certain mare has that she's hated for over two years.

Twilight Sparkle has been having nightmares for the past month. Every night, her dreams are filled with unspeakable horrors, and it all started when she'd received news that King Sombra had been captured and brought to the dungeons below Canterlot castle.

To conqueror your fears, you must face them first, and that is precisely what Twilight means to do.

Rated T for mature themes.

Chrysalis has kidnapped Celestia, so she has Twilight Sparkle right where she wants her!

And Celestia really doesn't want to hear about it.

A bit of silliness that I wrote in about four hours, trying to get rid of a writers block.

Deciding to find a wife, King Sombra arrives in Ponyville and finds the perfect mare: Twilight Sparkle. But how in Tartarus' name is he supposed to win her heart? Charlie Daniels, help him out!

This was inspired by an apparent cut scene from the episode “Slice of Life,” where King Sombra would’ve gotten into a musical duel with Octavia Melody a la The Devil Went Down To Georgia. So, I just ran with that idea and rewrote the lyrics to make it a Twibra story. Enjoy!

Now with reading by Lotus Moon!

Twilight Sparkle has spent months researching chaos magic, developing a new spell to unlock magic nopony has ever experienced before. But when something goes wrong with casting, Twilight finds herself turned into a Draconequus and unable to control her new chaos magic. If she ever wants to be a pony again, there is only one who can help her learn to control her new magic.

Of course, learning from Discord was never going to be simple. And after a while, being a draconequus doesn't seem so bad anyway....
