MLP/Undertale crossover.
Not a PWNY-verse story.

Long ago, the Monsters and Humans fought a great war. The Monsters lost, and were sealed in the Underground. It would take the power of seven human souls to break the barrier that kept them imprisoned. They only had six. And so the Monsters waited and hoped, praying that another human would find their way to the Underground. Some thought the seventh soul would give their King the strength to break the barrier. Some dreamed of a human who would be their friend, and save them all...or had nightmares of one who would bring back the war.

...but nobody came.

...but somepony did.

Eons after the war, with no way to tell how much time had passed above, a tiny blue filly with wings and horn fell into the underground, calling for her Mama. None knew the poor creature's nature or origins...but her soul was powerful with magic, even more so than a human soul.

None can know what will come...of this little 'Woona'.

Twilight Sparkle has never needed much to be happy: a book to enjoy, a research to carry out, and a Spike by her side. But after teaming up with and befriending five stallions to save the world in her first, fateful night in Ponyville, her life has been thrown upside down.

For she is now the Bearer of the Element of Magic, and ever since, trouble is knocking at her door seemingly every week: be it a monster attack, friendship drama, or the fact that Equestria seems to be sleepwalking from crisis to crisis, Twilight’s life will never be the same again.

FAQ
Q: If it’s not a harem romance, then why are the mane six and Luna genderswapped?

A: Because while it started as a deconstructive, character-driven take on one, we’ve realised that this character arrangement grants us far more creative freedom than what we would have using their canon incarnations.  Having M!Applejack, Rainbow Blitz, Elusive, Butterscotch and Phil Pie allows us to, essentially, make their characters our own, take them to uncharted waters, and introduce new plotlines and situations that haven’t been done previously and that just wouldn’t have worked if applied to the girls we all know and love. It’s, in a way, what keeps this story fresh, even when retelling the series for the umpteenth time. It mixes up their dynamics with other ponies and with each other in new, unseen ways, and makes it all the more interesting to explore.

Adding to this is the fact that Twilight, at the beginning of the series, is something of a blank slate, whose character development is informed by the quirks and personalities of her friends. Therefore, she functions both as her own, recognisable character and as an audience surrogate, who’s getting to know these guys at the same pace as the audience itself.

Funnily enough, Luna’s genderswap was never intended to have any relation whatsoever to the harem trope; Artemis was never supposed to be a Love Interest. Instead, well, let’s just say it fills in a certain, unaddressed headscratcher in the original series.

Q: Will there be shipping?

Yes, there will be romance. However, not only it will be what most people like to call a 'slow burn', but it's most definitely not the main focus of the story. If you're looking for a ship fic, you'll be disappointed.

Q: Is [character] genderswapped too?

No.

The only characters who are genderswapped are Applejack, Rarity, Rainbow Dash, Fluttershy, Pinkie Pie and Luna. Everyone else is their canon gender. Trixie is female. Starlight Glimmer is female. Should she appear, Sunset Shimmer will be female.

Discord, on the other hand, is something of a grey area, as they're a literal God of Chaos. Therefore, just as they can do pretty much whatever they damn well please, they can also change genders at a whim. However, should Discord adopt a female gender, her name would still be Discord, rather than the fanon Eris, as the word 'Discord' is genderless.

Q: Why is male!Pinkie's name not the fanon Bubble Berry?

There's multiple reasons, all of which are stated point blank by the character himself during his introduction in chapter one. It's mostly for meta reasons, but there's some plot there, too.

Q: Will you do [episode]?

There is an overarching plot, and the selection of episodes that get adapted and the way they do heavily depends on how they contribute to set up or advance said plot, or how plausible they are given the differences between the canon characters and their genderswapped incarnations.

Therefore, many of your favourite episodes may end up happening in entirely different ways as they did in canon, be mixed up with another episode, be relegated to a mere mention, or maybe just not at all. It all depends on how they fit the bigger picture.

I may or may not have just broken my hand against my desk when I jumped in surprise when William Grey told me this story was on featured, literally MINUTES within uploading chapter 9.
I'm sorry, just...
What?!
Mind-blowing, man. I have no idea how the algorithms work, nor how long it will last, but we're very happy about it.
Seriously, we wish to thank wholeheartedly to anyone who has read it, who has liked it, who has commented. This is our first published story, among myriad we have written yet never had the courage to put them out there. It really means a lot to us that people are responding positively.
Plus, that means I can claim moral victory, because I absolutely spent my whole weekend writing this instead of preparing the ppt for my monograph's thesis proposal for tomorrow.
So, yeah.
Thank you <3

This story is a sequel to Soft Spoken With a Big Heart

Takes place during the events of Head in the Clouds.

After the train wreck incident, both Fluttershy and Big Macintosh have developed a strong interest in each other. The problem is, they are both extremely shy ponies who barely speak out about anything. Two months have gone by and neither have been able to act on their feelings despite it being on their minds day in and day out. Is it possible for a relationship, or even just friendship to bloom if the two ponies in question are nearly incapable of voicing their thoughts and feelings?

A story of finding the courage to face your fears and make sacrifices for those you love. It's not important that you SAY how much you care. It's important that you SHOW how much you care.

When Luna becomes the unwitting test subject of an ancient spell she discovered, she gets more than she bargained for.

Now a male alicorn named Lucian, he is forced to wait for several months before he can go back to being the mare he once was. With the help of Twilight Sparkle, however, he realizes that his accidental transformation is not the curse he had believed it to be. Thanks to his new identity, he is able to move into Ponyville without being recognized, and gets to make friends for the first time in centuries, learning many important lessons along the way.

At the same time, however, Lucian must deal with his own long-forgotten personal demons; what can he do when his past begins to catch up to him? Can he protect those closest to him? And more importantly, can he even protect himself?

The answers, perhaps, may lie with his sister's greatest pupil... who may come to be far more than just a friend to him.

Note to readers: This story takes place between season 2 and season 3. Therefore, inconsistencies with season 3 canon may ocasionally occur. Consider it an "Alternate season 3," if you wish.
