It has been a decade since Twilight Sparkle was crowned sole Princess, and Equestria is at peace.

The Crystal Empire, not so much. King Sombra is apparently unkillable, despite all efforts. He returns several times a year to be destroyed, leaving behind his horn and always swearing vengeance. The jaded Crystal Ponies, some literally jade, have grown used to their tyrant attempting to return. Princess Cadance rules with her husband Shining Armor, while their daughter Flurry Heart excels in school. All is well.

All seems well, until Cadance begins to suspect that something is wrong with her daughter after the latest battle with Sombra. Flurry quite literally walks off a blast of concentrated dark magic. What Cadance discovers will shake her family to the core and upend everything she thought she knew about her daughter.

Flurry Heart is evil. If Cadance cannot save her daughter, she must stop her before it's too late.

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.

What if Celestia never wrote back? Like, ever?

I got the idea from 4everfeebrony's song.

I also wrote this on the go.
