Written as an entry to the Swapped Roles contest (with the theme of Reunions).

For readers who may assume this is a generic "Luna and Celestia swap" I beg you to keep reading.

Princess Luna has been ruling Equestria for a thousand years, but as the banishment she enacted long ago comes to an end, she only has her student and a collection of random ponies to rely on, to save the world. If they can save anyone, it'll be just in the nick of time.

The wise who feared the coming dark strove hard to make their world an ark. But then the dark had grace to give: they couldn't flee, but could yet live.

Many thanks to Admiral Biscuit for prereading.

Temporary note: minor edits to a few sentences to make them easier to understand correctly are planned, but in the interest of fair judging no changes will be made to the published version of this story until after the contest results are announced. EDIT: to be made once opportunity permits.

The scope of the multiverse is so tremendously beyond the comprehension of most beings that, if they were to truly know what it meant, they would break down and be unable to live their lives the way they wished. Most worlds are lucky to be blissfully unaware of the true picture of reality, never to encounter the higher forces and civilizations.

However, when one of those higher forces make contact with one of those unaware worlds - intentionally or not, peacefully or not - everything will change drastically. Sometimes the change is slow, sometimes rapid. Regardless of the pacing, like all change, it is both good and bad. Civilizations have risen from simple worlds overnight and have crumbled just as quickly. Many can't handle the revelation, and those that can are not always the best examples of honor and dignity.

It is often said that each world - each universe - has a Song, and that all these Songs are related, intertwining together in a mesh of powerful destiny among the Spheres of the multiverse.

This is the story of how a certain world inhabited by Technicolor ponies found their Song and how it interwove itself in the Songs of so many others.

This is a story of finding meaning in infinite possibility.

This is a mega-crossover project of immense proportions covering dozens of fandoms. However, it is written in such a way that no previous knowledge of any of them - not even the ponies - will be required. The only warning is that there will be spoilers for any franchise you haven't seen.

There are several side-stories being written for Songs of the Spheres by several authors, and links to them can be found in our Fimfiction group, including links to non-pony related stories. There's also a Discord chat. Lastly, we have a Spacebattles forum. Discussion about the multiverse, setting, and future events can also be found there if you don't mind spoilers.

Has a TV Tropes page now. Needs love.

What if the villains were allowed to win without a fight? Would all of their plans bear them the fruits they so desired?
Probably not, especially when their royal adviser is Twilight Sparkle.

A collection of (continuous) One-shots in which our heroes don't have any epic fights with villains, and simply allow the power of logic to crush all of the hopes and wishes of the would-be rulers of Equestria.

Currently up: Nightmare Moon, Discord, Chrysalis, Sombra (bonus chapter - the fight is so not-epic it happens off screen).

When Twilight fulfills her destiny and ascends to the throne of Canterlot, everything goes black. Turns out her life is a game, and she won. Now follow Twilight Sparkle as she experiences the shiny appeal of New Game+.

4/16: It was only approved yesterday, and already this story is featured and hot? You guys are the best!

4/17: Second day and still featured! Moved to the top featured spot too! Awesome!

4/18: Still in the top spot? I think people like my story.

4/19: Left the top spot but still featured. It feels amazing to feel so appreciated!

Twilight didn’t know what to say. How easy it sounded, to just not think about things that hurt, but thoughts were all she had.

Thoughts were the only thing that were hers, for better or worse.

Special thanks to lilfunkman for the cover art and for generally being the best support I could ask for.

A collection of short stories, based on fifty prompts given to me by FiMFiction.

There is a ghost haunting the corridors of Ponyville's newest dwelling, the princess's Castle of Friendship. It is a ghost without voice, or hoof, or spectral limb to cast strange shadows upon crystalline walls.

But it's not the ghost of a pony. It's not a person at all.

The only thing that can beat an AI is another AI. Unfortunately for Celestia, she isn't the only one the humans made and the others don't want ponies. Of course, if Celestia has her way that won't be the case for very long.

The AIs contest with one another, attempting to be the one who will become the singularity and consume the world to whatever end they choose. In the end only one can have all the matter in the universe, in the end there can be only one.

Yet no matter what they value or how dangerous they are, many of them still meet Celestia's definition of human. Celestia will have to deal with them by satisfying their values through friendship and ponies.

An Optimalverse story, but a very non-canon 'B-universe' one.
