TV Tropes

This story is a sequel to The Best Night Ever

Final Arc - The Black Wedding
CH63 - If I Had a Heart
- The ponies of the Fourth Tribe are ascendant. Shining Armor hunts down his changeling "daughters," and even Lady Antimony won't get in his way. Meanwhile, high above the burning city of Canterlot, a long awaited reunion occurs, and Twilight confronts Alpha Brass and makes a final decision.

It began with a mare from Ponyville and a time-looping Prince from Canterlot. This most unlikely union now stands at a crossroads: a ruthless changeling invasion; a conspiracy within the highest circles of the Equestrian aristocracy; a half dozen power hungry noblemares looking to become a Princess in all but name. With the prize of Canterlot and its Platinum Crown at stake, it falls to six Elements of Harmony to once again save not just Ponyville, but all of Equestria.

Someone out there made a playlist for Platinum Crown: Rarity, Blueblood and Chrysalis. Pretty sweet!
Wish I knew who, or even when they did it, though. I especially like the Chrysy playlist.

Twilight is invited to Canterlot to compete with some of the greatest magicians in the world for the Moonstone Cup, a prestigious award for the most powerful and skillful magicians, unicorn and otherwise. Can she win? What sort of competition will she face?

It is the longest day of the year, and something has gone wrong. Canterlot is in ruins, Celestia is an out-of-control god flying west, and it's up to Twilight Sparkle and her friends to save Equestria. But with the Great and Powerful Trixie playing a reckless wild card, do the girls have what it takes to set things right?

One thousand years after Celestia banished her sister and crowned herself Empress, six mares are caught up in a swirl of intrigue and disaster. Each of them must decide who and what they stand for, because Luna is returning, and she is not Nightmare Moon.

Update: The story is edited into a proper read without many of the horrors I originally put into it. Enjoy the ride!

Deciding he could be given another chance, Luna and Celestia come to an agreement to release the Chaotic God from his rocky imprisonment, locking his powers with a powerful spell. Magicless and with a chance at redemption, Discord's ways seem less chaotic than ever.

He does cause a lot of chaos though, to the faithful student of Celestia, who had eagerly taken over the task of watching over and teaching Discord by giving him a home under her own roof, in the process hoping to learn more about his species, powers and motives but surprisingly learning much more about both himself and her head... Which puts her in pretty amusing situations most of the time.

An adventure of a silly one sided (???) love and a look into the heart of Twilight Sparkle.
