This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

Life is full of challenges.

Pinkie Pie knows that, and will always try to help her friends smile no matter the circumstances. But when Pinkie's newest friend Sarah, a little girl from a strange new world, is faced with more challenges than anyone so young should ever have to handle, Pinkie begins to wonder if she really can keep the smiles coming.

Princess Celestia, tired of the constant pressure that ruling a nation puts on her, decides to take a day off and let Luna take her responsibilities for a day, something the younger alicorn is more than happy to do. She disguises herself as a pink maned pegasus pony named Sunny Skies and decides to go walking around Canterlot without any supervision. Unfortunately for her, not all parts of Canterlot are as safe as the palace, and she finds herself at the wrong end of a gang of muggers, who decide to kidnap her for a ransom when they see how much money she has on her.

Luna freaks out.

Celestia thinks it's hilarious.

"My name is Lyra Heartstrings, and you will not remember me. You won't even remember this conversation. Just like with everypony else I've ever met, everything I do or say will be forgotten. Every letter I've written will appear blank; every piece of evidence I've left behind will end up missing. I'm stuck here in Ponyville because of the same curse that has made me so forgettable. Still, that doesn't stop me from doing the one thing that I love: making music. If my melodies find their way into your heart, then there is still hope for me. If I can't prove that I exist, I can at least prove that my love for each and every one of you exists. Please, listen to my story, my symphony, for it is me."

Princess Twilight Sparkle has a problem: she's possessed by a question. It came from a silly little book. Now, after a week of poor sleep, Twilight relents. She has to answer this question, even if it kills her.

Okay, so it won't kill her, but Twilight is going to have to violate one of the biggest pony taboos in existence to do so. That's okay. It's for science!

After a rather disappointing battle with Discord, Applejack ends up on Earth and is found by a funny-looking brony named Garrett. Trials and tribulations may occur, but the question is: can she get back to her friends and find a way back home?

Waking up in an alternate universe in which you are a supervillain can be hard.

Finding out your friends are rebels trying to kill or overthrow you isn't very easy to deal with either.

But trying to solve the situation? That's a real horn cracker.

It occurred one peaceful night. Half of Equestria awoke to the sound like a double-shot thunderclap. A percussion heard in the skies and rattling windows from Apploosa, to Canterlot, to Ponyville. Nopony knew what it was or what it heralded for the world as it drew a line across the nation.

For Twilight Sparkle, this isolated incident might have faded from memory after a time, if not for the strange rumors of a creature sitting on the hill on the outskirts of town.

These are her thoughts given written form. These are Sparkle's Notes.

Report EVERYTHING to the Princess.

What are the chances your favorite pony was secretly a changeling all along?

Yeah, probably about one in one.

After an unknown accident Twilight Sparkle and Rainbow Dash awake to find themselves sharing the same body! Now they must struggle to hold themselves together as their world is turned upside down. How long can two ponies exist in a single mind? It’s a race against time as they search for answers before it’s too late. When all is said and done, you’ll never look at Twilight Dash the same way again.
