This story is a sequel to Upheaval: Reckoning
Equestria's fragments have reunited, and the power of sunlight shines once more within Celestia. With the remnants of the Old Kingdom destroyed, the Abyssal Throne sent away, the threat of Gravitas defeated, and Black Rose no more, Equestria now faces the encroaching darkness of Oceanus and his rebels.
But the stage is not yet fully set. Twilight Sparkle and her friends must gather what means they may before the battle is joined.
