Three hundred years ago, Equestria tried to assimilate Earth.
They failed. They fled, rather than face justice.
We moved on. We conquered the stars, we made a civilization that spans across the infinite void. We built true harmony between species.
We thought we'd seen the last of Celestia, but as a desperate mobile colony on the fringes of known space came to discover, we were wrong.

It is time to finish what was started by our forefathers.

In the year 2148, Earth Ponies discovered they were not alone in the universe.

Discovering an ancient cache of technology belonging to an extinct race identified only as the Alicorn, the Earth Ponies soared to new heights of technological advancement. With their newfound strength, they searched the galaxy for more hidden treasures of the Alicorn empire, soon discovering the existence of other space-faring races that shared their lust for progress and knowledge.

But when their fevered searching unearths ghosts that were better left buried, and mysteries better left unsolved, the Equestrian Galaxy is besieged by an ancient foe bent on nothing than the total destruction of life. Only one group of friends, led by a single Earth Pony soldier, can stop the coming darkness, all the while trying to answer the great question at the center of it all; what happened to the Alicorn Civilization and the Equestria that was?

It had been one year since Twilight Sparkle vanished in the battle against the evil unicorn Xander, and her friends were still trying to overcome the grief of losing her. On the anniversary of her presumed death, her friends gather at her memorial. What was suppose to be a day of remembrance was shattered by a strange metal object that landed right beside them. Their anger quickly turns to shock as a familiar unicorn emerges... and boy does she have a story to tell.

It has been several months since the disappearance of Twilight Sparkle..

One night, after watching her sister raise the Moon and set the heavens alight, Princess Celestia begins to bed down for the night, only to be interrupted by portal forming in her room. From out of the portal comes none other than Twilight Sparkle, garbed in strange armor.

Princess Celestia, along with Luna, Cadence, and Shining Armor, are overjoyed by the Element of Magic's return, but are justifiably curious as to where she had been and what she had been doing. And so, Twilight begins her tale. A tale of survival against impossible odds. A tale of a people fighting for the most basic right of all sentient beings. The right to exist.

This story is a sequel to Upheaval: Breaking Point

Following the events of Breaking Point, Twilight Sparkle and her friends discover that Equestria's demise may not come from an enemy invasion, but from within. The Barrier Lands and the Heartland begin the slow and uneasy process of reuniting into a single Equestria, but this long-delayed joining is already in danger at its conception.

With Celestia's power in her grasp and her agents by her side, the wheels of Black Rose's plans for Equestria's future continue to turn. However, her brazen gamble has done more than just bring down a centuries-old barrier. Ancient powers begin to stir: the remnants of a dark period in Equestria's history, the immortal inhabitants of Celestia's homeworld, and a rising tide of darkness coming ever closer.

Equestria is a land of magic and harmony, a peaceful realm ruled by immortal and benevolent monarchs. At what cost is this possible?

Following the discovery of a strange and powerful device, Twilight Sparkle is whisked away to the edges of a land she thought she knew so well. Here, surrounded by ponies whose very existences have been kept secret, she must contend with vicious enemies, hostile allies, and the truth.
