You've essentially written a cosmic-horror synopsis disguised as an endgame event. The core strength is that the conflict continuously escalates beyond conventional power scaling. Every layer that appears supreme is eventually revealed to be subordinate to something more fundamental. Creation loses to concepts. Concepts lose to authority. Authority loses to meaninglessness. Meaninglessness loses to the realization that even the possibility of meaning may have been accidental.
Here's an expanded 2,500-word-style summary version:

THE ABSOLUTE SERIES: THE LAST OVERRIDE
Endgame: The Ragnarok of the Omniverse
The final war of existence was not born from hatred.
It was not born from ambition.
Nor was it born from conquest.
It began with something far more dangerous.
Imbalance.
