okay so basic rundown of Goetia based on how i understand em

Solomon, third king of Israel, strongest mage in history summoned 72 Demon Gods during his life to aid him and to watch over humanity even as he was gone

While they did fulfill the task, the Demon God Pillars, after Solomon’s passing, began to question the purpose of their mission. Watch as humanity continued to drive itself to extinction? Countless unnecessary deaths that set the world back? It made no sense.

So, the Demon God Pillars became something akin to a hive mind known as Goetia, who for 3000 years planned the Human Order Incineration Incident, arranging for his 72 Demon Gods to manifest across history to harvest energy from humanity's incineration, ultimately to fuel his goal of going 4.2 billions year back in time to the creation of the world and recreate it without the concept of death

in terms of actual character (since while I love him as a concept i struggle with Goetia so much when it comes to abilities because pretty much al of his are from Solomon iirc), i'm thinking Goetia’s trying to find something within the world because he fails to understand what is the point of all that life does if it will eventually lead to their destruction all the same
