There are many stories where Twilight tells off her friends after the Wedding. But that's not really Twilight's bag, she gets worried she's failed, or depressed, not angry. So here is a different bridal path, one where Twilight acts decisively to try and redeem herself in the eyes of her friends and sovereign, and ends up travelling to places she never imagined, facing dangers and foes she never dreamed of and making even stranger friends. Of course, there is still a 'reason you suck' speech delivered, but delivered by the last person anyone would expect...

What do you do when given the choice between your existence, and the lives of your friends? What would you give up? Your happiness? Your life?

Your soul?

Twilight Sparkle embraces oblivion for her friends, and awakens the Soul of Hope.

Warnings
1. I enjoy writing fight scenes, so this story will be more violent than most MLP stories you'll find... I think. It won't be grimdark violence, but still.

2. This is an Alternate Universe story. The content within this story may or may not match up to canon.

This story is a sequel to The Dragon Sage

After the events that took place in The Dragon Sage, Twilight and Spike have quietly started living and loving in their castle. Other ponies are bound to find out, so how will they respond? What does this mean for their friends and neighbors?

If you haven't read the previous story, I suggest it, but it is not necessary. Most characters and references to The Dragon Sage take a back seat role in this slice-of-life story. It's more as an extended epilogue than anything else.

Spike, the now prince of all of Equestria. Handsome and Charming, and born a thousand years before he was supposed to, is now a completely different being.

Spike, during these extra thousand years, has been training in all the fields known, his long life allowing him to retrain all that there is. Although with all good things, comes a price.

We now find us to the day of when his birth was supposed to take place, Spike is now a slightly different being. All that he has learned and experienced has changed the way he acts and feels, love not being part of that scheme.

But one day, he meet's a mare by the name of Twilight Sparkle, and his life is soon flipped. As he soon get's attached to the mare, as our lucky duo are soon sent to Ponyville.

How will the story change with a new Spike? What are some of the hardships Spike had to experience in order for him to mature from a prick teen into an sightly less prick teen? Why is Spike the why he is now? And will our lucky duo succumb to the gross element known as love?

Idea given to me by Smurf.

Spike's happy world has always revolved around Twilight. From his hatching to their adventures in Ponyville, he has remained a faithful companion and loyal friend. But why is it that he has remained a baby for all of these years? There is so much about dragons that they do not know. In a rude awakening, Spike receives a letter from Princess Luna who promises to help Spike meet his potential. But how much will he change? Will his friends see him differently? And how will his life with Twilight evolve?

(set after season 4 and rainbow rocks).

While Big Macintosh and Twilight Sparkle have been dating strong for almost a year, she has yet to meet the family in a full fledged reunion where she will be completely immersed in the family, and their culture. For better or for worse...

Unfortunately, even though many family members support the likely new addition to the Apple Family, few are weary of her Celebrity Mage status, let alone that she is the newest Princess of the Realm.

(Tags: Humanized, modern tech is apparent but magic is still present. A few OC's in her guard task force.)

Our tale begins after Twilight Sparkle tries in vain to expose the evil Princess Mi Amore Cadenza, but ends up heartbroken and left all alone, crying on the steps of the great hall. Except this time, it is not Cadenza that comes to comfort her...

(Story was composed pre-Season 3 and is inspired by lore from the Diablo series.)

Crossover of MLP/FNaF. Years ago as a filly, Twilight saw something at Freddy Fazbear's Pizza that is so terrifying, she doesn't want to talk about it ever! In the present, now a grown-up mare and a princess, she and her friends must oversee a week at the place, staying the night as the restaurant is in its final year. As Twilight faces her nightmares and fears, she and her friends must survive against Freddy Fazbear and his animatonic crew, who for some reason wants the new princess dead.

This story has nothing to do with the ones I'm working on in my regular MLP timeline, so it's a separated timeline.

Twilight didn't know what came over her. At one point, she was having a wonderful tea party with her friends, and the next thing she knew, she was trying to kill the princesses.
This could have something to do with the fact that nopony would listen to her at her brother's wedding, everypony thinking she is crazy, or even the fact that Discord was set free without anypony noticing.
She finds herself at Celestia's court, facing crimes she didn't commit.
"Twilight Sparkle, for stealing the Elements of Harmony, attempting to kill me and Princess Luna, and Betraying everything you were supposed to protect, you are hereby banished from Equestria, never to return!"
Celestia's words continued to ring in her ears as she followed the road out of Equestria. She would never see her friends again.
