I've been working on a better version of this whole concept expiramenting with it, and I think i have enough for a plot synopsis which I'll be posting a synopsis of the plot(A/N: i may have by mistake deleted ch1 so I'm sorry):
—
"In the world of Aurelion a goddess named Lumiel who was once human ruled as the sole divine sovereign for eighty eight millenia after much war, and conflict the entire world(A/N: equal to two earths in size) united under her peace then slowly their zeal burned as a unifying flame under the sole goddess. Thus was peace, progress, and prosperity as she wasn't some distant divinity she regularly walked, laughed, and sang with her people but all that changed when in the world of DC Argus was doing some dimensional experiments when the opened a rift to Aurelion a vastly superior techno-magic world that dwarfed everything they had. Then came human greed labeling Lumiel a Tyrant so the Justice League go in expecting one."

That's the core concept I was going for a non eldritch entity this time i know but I thought it worked out quite well. Let me know if you like that idea or prefer "The Eldritch Expirence in DC"
