Twilight was always fated to be the savior of Equestria, along with her friends. But fate can be so easily altered. What happens in one alternate realm when instead of marrying a unicorn, Twilight's mother had instead married an earth pony, resulting in her daughter being hornless? Without her magic, Twilight's future and destiny are far less certain, as is the destiny of all of Equestria.

However, destiny is not so easily set off course. When the princess of the night returns, can one little earth pony hope to be the one to help her damaged heart?

Now with a TV tropes page! Thanks to redandready45.

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.

Twilight Sparkle is undeniably a prodigy and has the skill and knowledge of a unicorn five years her elder as well as the power of one as well. This knowledge and power has drawn Princess Celestia's attention, with the alicorn beginning to wonder if the young unicorn will be the one to fulfill an ancient prophecy that would save her sister. A prophecy that would have come to fruition, had the alicorn's own checkered past not come back to doom the filly to a life of fire and brimstone.

Story So Far (Been awhile? Get up to speed by checking out this blog!)

A flip of a coin. A twist of fate.

Twilight Sparkle, younger sister of Princess Celestia's personal student, Shining Armor, grew up listening to her brother's bygone dreams of joining the elite of the elite: The Royal Guard.

Now, fresh out of the Academy, this young mare is ready to prove herself equal to the deeds of the great soldiers she read about as a filly. Too bad the princess she ends up protecting isn't Celestia.

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....

In a world where she sees from a distorted perspective, all Twilight Sparkle can do is cling to the one pony she knows will never let her down: her teacher, the princess... no matter which princess her addled brain tells her that is. Twilight's used to rewriting letters, but when she's the one being rewritten, she finds the sensation to be altogether different.

This story is a sequel to Twilight Sparkle of the Royal Guard

Between castle gossip, professional rivalries, a blooming romance, and a mysterious malefactor still at large, Decurion Twilight Sparkle has a lot on her plate. Hopefully, she'll make a few new friends as she moves towards the destiny she's chosen for herself.

As per usual, big thanks to Magello for the rad cover art!

In a freak accident from the Cloudsdale weather control team, Twilight is struck down by an errant lightning bolt. But the veil of death is relatively thin...

Discord never betrayed Equestria for Tirek, aiding in returning the magic to all the drained unicorns. As a result, Celestia deems him ready of a "small" gift: The Archduchy of the Everfree, technically making him the highest noble under the princesses.

Naturally, this shocks everypony, including Discord himself. Now of course his lands will some have some chaotic magic and strange laws in effect, but that doesn't mean he doesn't take the noble thing a little seriously. Why is anypony's guess, but it'll be entertaining to watch.

Seath the Scaleless, White Dragon God of Verdite, Traitor to the Everlasting Dragons, Duke of Anor Londo, Grandfather of Sorcery, and now the new friend and mentor to Twilight Sparkle? What will happen when two like-minded souls from opposite ends of the morality spectrum match wits? And what will remain in their wake?

A somewhat more meta twist on a MLP/Dark Souls cross-over, inspired predominantly by a few pictures I found of Seath and Twilight together, and my bewildered discovery that for all of the stories on this site that cover these two franchises, there's only one that focuses on Seath the Scaleless and so far it hasn't seen any updates in over a year ( http://www.fimfiction.net/story/68621/scales for those curious).

For those who haven't played either the King's Field or Dark Souls games worry not. I'll do my best to either explain the lore of both in the story itself, or add an author's notes for anything that gets referenced.
