Twilight and Shining Armor have a little sister named Light Step. Everypony tells Light Step how lucky she is to be related to such great heroes.

Light Step wishes she could smother them both.

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.

Cadance and Twilight have discovered something about the Alicorn Amulet. Whenever someone rejects its promises of power, it weakens the Amulet's magic. In theory, if enough ponies should be tempted by it and reject it, it would destroy the amulet forever.

They summon the help of volunteers from across Equestria, in the hope of destroying it for good.

Twilight Sparkle wakes up in a strange, mysterious room, with no idea how she got there. Alone, afraid, and confused, she is left to make sense of this position she finds herself in.

That's the basic premise, but that's only part of the story. You see, fair reader, your comments can change the course of events. Go ahead, leave one. See what happens next update.

Due to the interactive nature of this fic, I cannot promise regular updates, unlike in my other stories. Nor will I say anything else about it at all - for you are in a position of power. If I tell you anything, it'll ruin the experience. It's a comment-driven story, after all.

The story is now complete. It's still a readable story, but it's no longer active.

Serves as an optional prelude to Songs of the Spheres.

There is a forum related to this story: Influencing the Influence. It contains supplemental material, but is definitely wrought with spoilers.

-GM, master of influential decisions and the interactive story.

A K Yearling, perhaps better known by her pseudonym Daring Do, has passed, and she left behind a legacy. Her entire vault was left to Rainbow Dash and Twilight Sparkle, including one particular artifact coupled with an ancient mystery the adventurer never quite solved.

The Seven Sided Chest of Chicomoztok, a mysterious artifact connected to an ancient legend, one that Yearling was puzzling over in her final days. This mystery has now passed onto Rainbow Dash, Twilight Sparkle, and their friends. This one mystery will lead them on a journey that spans countless worlds, and is bigger than anything Yearling ever imagined.

They are about to discover the Realms of Existence.

Updates Friday.

-GM, master of sevens.

No one alive today can say where she came from; simply that she has always been there.

And yet, few ponies have had a greater impact on Princess Celestia's life than Raven, her most faithful aide.

Inspired by and based off of a headcanon put forth by Heir-of-Rick, though perhaps a bit less insidious than what he had in mind. He very kindly provided an alternate version of his image for me to use as my cover image! Text added by me.

All comments and criticism very welcome!

Translations: Chinese, Spanish!

Starlight Glimmer awaits her punishment at the hooves of Twilight Sparkle and her friends.

Twilight Sparkle broke time when she got her cutie mark. Now Twilight and Sparkle are sisters from another time. Twilight is hailed as the potentially greatest light magician of all time, and already has a reputation as a hero by the time she goes to Ponyville. This isn't her story, not primarily.

Sparkle is an orphan - her dark magic killed her parents. She lives with her brother in Canterlot's industrial sector because they can't afford anything better. She can't leave either. She's a natural dark mage; while Sparkle won't go mad like Sombra, her reputation is hardly any better. Worse, the law doesn't see her as a good pony.

The fact that the dead don't stay dead around her, or that Thorn - Spike's double - is an undead, soul-eating abomination, are other matters altogether.

(Also has some Slice-of-Life, but fimfiction tags won't let me put it with Adventure.)

Has an ask blog to go with it: Ask Sparkle and Thorn.
Also has a TvTropes page: Split Second Tropes.
