There is a flood on the horizon. Equestria's enemies have united, and the coming tide will not only change the course of history on one world, but two, and bring about a monumental meeting that will bring brothers and sisters from those two worlds together.

At long last, the downtrodden will rise.

The battle begins.

A minor accident at Sweet Apple Acres sends Big Macintosh to Ponyville in the middle of applebuck season. At first, things seem fine. But then some of the mares begin acting a little...oddly.

Then very oddly. Turns out every other stallion skipped town for a very good reason.

The Metro tunnels of Stalliongrad shelter the last remnants of ponykind from the ravages of the Apocalypse. Beneath the earth, ponies struggle to survive against mutants, radiation, and each other. But when an unstoppable threat emerges from the darkness of the Metro, one pony must brave the shadows to save not just his home, but the very existence of his people.

When strange ponies from another world suddenly pony-nap all her friends, Pinkie Pie must find a way to defeat their master all on her own. Blamed for the crime herself, she has no help from Celestia and just about every pony in Ponyville is convinced that she's finally cracked. Who can she possibly find to fill in for the other Elements of Harmony, and help her defeat the ancient evil behind it all?

This story occurs after Discord is defeated but prior to the rest of season 2. Story is featured on Equestria Daily and is now officially a 'six star' rated story! Full size image can also be found there.
