So these days, I am thinking of just rewriting the whole fanfiction, removing DC entirely, and focusing on a God World—a Beyond-dimension world that connects with all the multiverses and omniverses—then expanding out and conquering other worlds, or something else you might have in mind.
Some concepts in my mind.
God World
True higher-dimensional domain.
Its inhabitants:
treat universes like territories
breed civilizations
engineer heroes
weaponize narratives
The Beyond World
A dimensional civilization existing above ordinary universes.
Not merely "another universe," but:
a realm from which universes are observed, cultivated, traded, invaded, archived, or consumed.
Think:
worlds = islands
multiverses = oceans
omniverses = clusters of realities
God World = Different-dimensional continent beyond them all
Worlds become resources
Different universes produce:
faith
souls
mana
concepts
stories
destiny
emotions
technological singularities
God factions harvest them.
Better antagonists than DC
You can now create:
World Devourers
Concept Gods
Narrative Parasites
Civilization Harvesters
Higher-dimensional monarchies
Dead omniversal empires
