The tale of a self-destructive reality

Long long ago, before the dawn of time and space, a being of unfathomable scale and power took its last breath, its limp body sinking through the surrounding void, veins bleeding time and body rotting into universes, but some universes were made of flesh that wasn't so decayed, that was fresh enough that it still had some of that infinite power that every primordial scavenger sought to harness, and harness they did, creating vast inter-universal empires headed by warlords wielding god-like power, who hoarded their territories like raccoons, if raccoons were so inclined to hold territory, but some raccoons are more ambitious than others, and warlords were no different, as one of them, Ygadle, had a scheme, by using their near-infinite power, they could repurpose one of their universes into a device known as the Eternity Engine, a hyperspherical construct, quadrillions of light years in diameter, with the capability of pumping the temporal blood back into the corpse from which all reality grew, and in doing so, reversing the flow of time itself, allowing the warlord to revitalize the putrid remains and harness even more of the god-being's energy to conquer reality, but there was just one issue: every other warlord knew about the Eternity Engine, and so every faction came down on Ygadle in a war lasting billions of years, where soldiers died by the trillions for only an inch of progress, but even after Ygadle and their forces were long gone, the other warlords fought over control of the device, extending the war into uncountable epochs, until finally, the last warlord, Glthmir, stood triumphant as the sole, all-powerful dictator of existence, but as the Eternity Engine was built to provide an advantage in the turf war, and Glthmir was already the most powerful being alive, any additional power granted by the Eternity Engine would be superfluous, but an unquenchable lust for ever more power drove Glthmir to activate it anyway, as everyone in existence watched with awe that swiftly turned to horror as the Eternity Engine worked too well, the flesh of the corpse became too revitalized, and shook the foundation of reality as the god-being, whose death facilitated the continued existence of all this new life, arose once more and carried on its way, completely oblivious to all the history, civilization, and lives that were lost by its reawakening.
