The Sun and Moon; both powerful symbols of magic. This is a constant that seems to hold true across many worlds. When a conjunction of the two brings the power they represent to bear and the walls between worlds is breached as a result, one young man's life is changed. Having fallen from his own world, he lands in a realm of magic and populated by creatures he once considered fictional.

Now fate has left him with the expectations of adapting to this new world and the trials and complications that come with it. Amid it all, his passage stirs up old memories that some would rather have left lost and forgotten, while the world itself is left with the scar of his arrival.

While it is true that coincidences are common and not every event is an omen, the line between the two can be paper thin.

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'.

'Do not trust an alicorn who weighs any less than her operating manual' - Author of this Guide

Sometimes your alicorn throws a temper tantrum and runs around the house turning off all the lights while declaring herself a new breed of adorable evilness. Sometimes sibling squabbles leave you with a tearful alicorn refusing to raise the moon and allow the day to end. Keep calm and read this guide. This guide will walk you through how to safely contain evil dark pony overlords using readily available household implements such as the humble cardboard box. And if all else fails, it will at least help you make effective use of the astrophysics of alicorn anatomy to manually override the raising, lowering and general joyriding of various celestial bodies.

This is a standalone story, but it does sort of have a 'previous episode' you can read here. Reading it is not required to enjoy this particular story, but it's a fun short read in its own right.

Sort of my Christmas fic. I decided to get it done early as I'll be working this Christmas. Again. Happy Hearthswarming, everyone!

I am now Princess Luna, and it’s not as fun as you might think. I don’t know what’s going on, how I got here, or what I’m going to do. Princess Celestia thinks I’m crazy, that I’ve lost my mind…

But something tells me I’m stuck here… so one way or another, I’m going to have to get used to this new life. Now if only I could figure out this stupid Magic stuff...

Story by Pinklestia with the collaboration of Rainbow Sparkle for the first three chapters.

Sablewing the Wicked, a black-hearted dragon with an immunity to magic, invades Canterlot with his army of diamond dogs, goblins, and kobolds. As they attempt to defend their kingdom, Princess Celestia and Princess Luna are captured and imprisoned by the foul reptile, and he proceeds to take over the entire city. A rescue attempt made by Princess Cadence and Twilight Sparkle is then performed, and immediately thwarted, resulting in their capture as well.

Having used the Elements of Harmony to save the Tree of Harmony recently, and being one pony short of using them anyhow, Twilight Sparkle's friends find themselves in the worst predicament imaginable. After raiding the library in the Castle of the Two Sisters in search of an answer to their problem, they happen upon, and then proceed to use a spell that shoots out into the multiverse in search of brave, suitable heroes to combat this monster.

Answering the call, four strange characters come forth: The Green Knight, Orange Knight, Red Knight, and Blue Knight; each powerful warriors in their own separate rights, who have honed their expertise in the field of beating the ever-living crap out of anything that has the sheer balls to simply be standing in their way.

Having been bored out of their minds in their home dimension (and being threatened that they would never return should they decide not to help), the four knights jump to the challenge to RIP AND TEAR and rescue some more princesses. They set off, weapons and sandwiches in hand, to kick some monster butt, crash some castles, and take names as violently as physically possible!

...Oh, and a certain mailmare with strabismus joins along on the mad adventure.

David never did have an exciting life. He had a somewhat stable one, along with his roommate, which he considered to be his best friend.

He had a lot of expectations for his future, most were... Far reaching, so to speak. But nothing too crazy.

At least, that's what he thought.

And let me tell you, turning into a blue horse was not something within his expectations.

Disclaimer; Earlier chapters were written when I was still inexperienced. Newer ones are better in quality overall.
