When a small filly calling herself Sonata Dusk emerged from the mysterious portal within the castle, Princess Luna expected many things. What she didn't expect was for the filly to claim that she was actually a siren, banished from Equestria a thousand years ago. Despite her initial surprise, Luna makes an unexpected decision, and takes the filly under her wing.
Several years later, with the impending return of an ancient evil, Luna sends Sonata off to the humble little town of Ponyville, in the hopes that she will be able to learn the true value of the magic of friendship.
But Sonata isn't quite keen on interacting with other ponies. After all, ponies would never accept a singing sea monster as a true friend... right?
First story of the Sonataverse.
Edited by Retirw-Tsitra. Cover art done by Violise.
...Huh. This is a rather original concept.
Not a reverse-world where Luna's good and takes an apprentice. That's happened a jillion times. But using SONATA, now...I am intrigued.
Only because she seems too ditzy to be a villain.
No one ever stops to consider that it's all an act, and that Sonata is really the most devious of all three Sirens. Oh, the Rainbooms shattered their pendants and took their magic away?
"Phase One complete."

I lol'd,
So... Who are you planning on making the new Mane 6?
Update soon!
Awesome sauce!
Best thing ever!
Anyway, I think that's cool that Sonata doesn't want to make friends because she's scared they'll judge her for her siren past. She's not a recluse like Twilight!
I vote Sunset for Honesty and Twilight for Background Pony 108!
Cadence takes on Sunset's role? I don't get it.
my only complaint is the chapter was so short lol I cannot wait for the next update!
Sonata: "mmmm Taaacooo.."
Last I checked, vegetarian tacos don't exist.
Dusk Shine is best Flash Sentry!
Really great story.
I'm looking forward to seeing who will be the other elements.

Nowadays, almost everything can be made into a vegetarian dish! Quorn meat can be used in tacos instead of the regular stuff - isn't science awesome?
Uhm, yes they do. Try googling 'vegetarian taco'
Anyways, I'm really liking this story so far! A bit of an unexpected romance there, but I doubt many people will complain.
And perhaps a mention of the shipping in the description. I've found that people like to know the shipping before they dive into the story
Just don't forget that romance tag if they do end up getting together
6102687 No shipping yet; I'm just including that in for future story lines
Awesome update!
So we have potential element bearers: Amethyst Star, Sugar Belle, and Night Glider. Interesting choice. I do hope we see the Party Favor and Double Diamond as well. And yes, the fight between Pinkie and Sonata was funny.
Also I'm now curious about this event at Taco Spell.

Much like the "noodles incident," we do not speak of what happened at Taco Spell. Which is to say, of course, that nothing happened.
You get me, homes?
Nothing. Happened.
Oh gosh, I thought Amethyst Star was Starlight Glimmer!
Party pony hair is best hair!
oh sonata
I'm not surprised, whatsoever.
CocoSpike?
... I accept.
So, wait. We've met... six or seven other ponies. So some of the characters that appear to have met Sonata are not Elements... hm.
Methinks Sonata be a wee bit obsessed...
Oh!
My!
Gosh!
That was so fabulous and amazing!

Can't wait to see what happens next!
6100682 Last I checked, hayburgers did exist. Your move, sir.
I doubt Amethyst Star realizes what Sonata Dusk actually is. From the way Star was talking, I got the impression she was suspecting a changeling.
I thought that was Twilight!
6118637 There is no Twilight, only Dusk. He's in the guard.
I was listening to Youtube while reading, and a commercial for Sonata cars came on, and I laughed internally.
Quote Flash, why don't you!
Jeez, Amethyst, that's harsh!
This will be interesting...
Thank you thank you thank you thank you thank you thank you for not picking the name "Daymare Sun."
I don't care what arguments anyone presents, I don't care if "daymare" is in the dictionary, and I don't care if the word's first use was recorded in the 1700s.
"Daymare Sun" is the second stupidest name I have ever heard for a pony. But only the second, so that's still something, I guess.
Oh, Sonata Dusk...
6151571 So what's the first?
6153597
Electric Guitar.
6153643 ... I just had to ask.
I think Starlight traumatized Sugar Belle.
Amazing chapter, I love how Luna is not passive like Celestia was in the series.
THAT SONATA IMPRESSION AT THE END THOUGH!
That was amazing! 
6154474 Most likely
And yes, it was awesome
For some pens writing in lyrical tricks is how they can get their very best kicks.
But now, the story is moving along; praising this tale would not strictly be wrong.
Good luck with the next, oh weaver of tales. Surely I doubt it would be one that fails.
6230011 well said my friend
6107052 When I was first editing this, I thought the exact same thing.
I applaud you for managing to write Zecora so well!
Zecora's dialogue is AA BB, not AB AB. Don't be like me and write her dialog like a couplet.
6287723 It was a very special tennis racket
That was just amazing! Not to mention super sweet!
Amazing cover art, too!
Poor Amethyst, having a crisis of faith.
I'm starting to think that Sonata may not actually be the element of magic after all.
