Equestria and the Crystal Empire have fallen to the Changeling Hegemony, led by the brutal Queen Chrysalis at the head of a mechanized horde of guns and tanks. Princess Cadance stayed in the Crystal Empire; Princess Twilight stayed in Equestria. Chrysalis rules the continent, only defied by Nova Griffonia, the poor Griffon colony in the north.

Across the ocean, the Griffonian Reich pledges to reclaim its lost territory, sundered by revolution a generation ago. While the Alicorn Sisters retreat to New Mareland, Princess Flurry Heart and Shining Armor turn to Aquileia, the Republic born out of the ashes of the Griffonian Reich. The Kaiser of the Reich is only a child, subject to a regent bent on war and conquest.

Flurry knows the Reich and Chrysalis have worked together.

She knows that war is coming to Aquileia.

She knows that Celestia and Luna abandoned her mother and Twilight Sparkle.

She knows that the world is on fire, and she is the last true Princess of Ponies.

She knows she will go home.

I got dragged to Equestria by pure accident due to an experiment gone 'wrong', roughly forty years before Nightmare Moons' arrival.
No matter what I do, as a pony-changeling hybrid, something will change with Equestria. I just hope I don't doom the country before Nightmare Moon even arrives... Or worse.

This is the first story I ever tried to write professionally, so there WILL be errors, for that, I apologize in advance.
I'm editing and proofreading it on my own because I literally suck when it comes to using this site competently.
Lastly, I am a slow writer due to IRL getting in the way but I will try my hardest to settle the story down whether it's popular or not.

Fair warning, there may be spoilers in the comments.

Thank you to Little Tigress for the fantastic cover art.

Research log #579

It's been over one and a half years ago since the last activation of the device, though the magical signature hasn't changed it seems... weakened, to such a degree that the re-activation is impossible.

As described in the notes of research log #249 any attempt at providing the device an artificial source of magic to power failed, the device simply needed more energy than even the combined magical power of both Princess Luna and Celestia were capable of providing. You must be wondering now, I've already described these circumstances in previous logs so why bring it up now?

Simply said I'm out of options, every attempt of reactivating the device have failed and I'm only left with a single choice. I'm going to have to reverse engineer the device in an attempt to understand the mechanics with which it operates...

...At the risk of maybe never being unable to reconstruct it later.

I'm so sorry Fluttershy, I never should have involved you or any of the girls in the exploration of this structure. I hope that if we ever see you again you can find it in yourself to forgive me.

In the true sense of Mass Effect, this story will be CYOA (Choose Your Own Adventure) giving you the reader the choice to decide the action of our protagonist.

I hope you enjoy!
