Ok so me and @graementality were making CCCC predictions and theories and we thought of Harmonia not being real
Since whole wasn't originally meant to be "cannon", we came up with Soul turning to religion go cope
Just like how humans turn to religion to cope with the inevitability of death, Soul "created" Harmonia to cope with the loops and that he's doing it "for Her". And since he kind of "created" Her and is the only one seen praying to Her in Dream, he's kind of like her Priest
Also, Grae talked about the line "Here in my kingdom, I am your lord" in TSE:
(Both screenshots are Grae talking)
Now, I don't *exactly* agree, but it made me think that the lord Here would be the obsession with Harmonia/Whole . But Soul, the Ego, started seeing himself as separate person from whole/Being almighty is a really interesting idea
Like he's not almighty, but sees himself that way bc he's the Ego! The mediator between Heart and Mind! Atlas, the one supporting the sky! He's obv the most important!
Thus he becomes the lord of Heart and Mind and fuelling the crash out that is TSE
