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....

After putting on the Element of Magic, Sunset Shimmer was shown just how much of a monster she really is. But that wasn't all the Elements did to her.

Sunset has now been forced to serve penance by answering any question truthfully and by doing anything asked of her, whether she wants to or not.

And she really doesn't want to.

Until all of the hatred in her heart is gone, Sunset is at the whim of her peers, unbeknownst to them of course. Can her new "friends" help her down the road to redemption?

If not, there's always that other Twilight Sparkle she keeps running into.

A thousand years ago, Princess Celestia banished her sister to the moon, that much we know. What wasn’t known, and what Celestia kept secret was that before her banishment, Luna had given birth to a foal. Now a thousand years later, as Nightmare returns to Equestria to bring about Eternal Night.

Twilight Sparkle, protege of Princess Celestia, struggles against the tyranny of this ancient foe. But how will she be able to save herself and her friends when the truth of this ancient legend crashes down upon her? Twilight will have to confront herself...and her heritage.

Polaris501

Failing once in her attempt to take Canterlot and failing again in her attempt to take down Twilight, one would think Chrysalis would have cut her losses and let things be, but the queen has once again appeared, this time in broad daylight with no disguise and no army. Her weapon of choice? Diplomacy.

Now Twilight is having to deal with the changeling queen, but surely putting up with her antics will be worth the knowledge she's willing to provide about her mysterious race and the potential undiscovered agents still within their midst...right?

Takes place before Magical Mystery Cure and diverges from there.

Seeing a little of herself in the former siren, Sunset embarks on a mission to help Sonata find friendship.

As Twilight comes across another new book, she notices that there was a spell that had a peculiar outcome: nothing! She cant believe that this is true and wants to try it out. However, she needs someone to test it on...more specifically an irritated dragon, wanting to go to sleep.

Edit: This story has been Featured! Woo!

Twilight Sparkle has too much magic, and it will take her decades to learn to control it. Her spectacular loss of control during her entrance exam only proves that fact. She is a danger to herself and others.

After Sunset Shimmer’s disappearance, Princess Celestia needs a new student to bear The Element of Magic to defeat Nightmare Moon. With all of Equestria at stake, Twilight Sparkle…is not the pony she needs.

Princess Celestia seals Twilight Sparkle’s magic with the distant promise of one day teaching her.

But there are two diarchs of Equestria. Amidst a lucid dream, an offer is made.

“Hello, Twilight. Would you like to be my student?”

This story is a sequel to Nigel M Chalmers, Emperor

(15/10/2015) Turned status back to incomplete pending an Epilouge and Alternate Endings chapter as per comment suggestions.

After being banished by Celestia for his misdeeds, the alien Emperor of the Crystal Empire is back... and out for revenge.

Emperor Chalmers is not a happy space man. After being stabbed in the back by Equestria, he was sent to the depths of the Underworld. Kicked out for causing too much trouble for the wardens, Nigel now has the chance to take back his empire and show Celestia just how disappointed he is with her.

This time things will be different. This time he has friends.

In the warmth of her cloud home, Rainbow Dash is about to turn in for the night when she hears Scootaloo crying outside in the middle of a vicious blizzard. Plucking the freezing filly from the snow, Rainbow hopes to provide some much-needed comfort for the otherwise tough young pegasus, but she uncovers a disturbing reality that she knows she cannot handle alone.

Knowing only one pony that could really help her out, Rainbow enlists Twilight’s help, determined to set things straight for Scootaloo. But what Rainbow doesn’t know is that in her efforts to provide a better life for the filly, her friendship with Twilight will develop into something more.
