Egyptian link with Christianity
If the next games takes us to Egypt, either through a main title or maybe an Atreus spin-off, I think when we met the Egyptian god Seth there will be nods and references to him actually being Yahweh.
I was reading on how Gnosticism came to be, and one of the main notions that started it all was the fact that people began to look at the myths and noting that the gods weren't "all good". One thing that led to this was when people were retelling the Exodus myths (the ones were the Jews are freed from Egypt because Yahweh fucked with Egypt with all the plagues) the Egyptians felt kind of offended. The notion was that a foreign god won over their homeland gods. Eventually this led to the idea that all the plagues and curses that the jews were retelling was actually the works of Seth, the god of chaos, associated with the threats to the land and everything foreign to them.
BIG IF here very Marvel plot but maybe Seth will be Yahweh or maybe just nods to this (like a pre-Yahweh, Yahweh without his people or something like that.) I think this kinda fits the vibe of the series.
You can say that this is idiotic, just leaving it registered here just in case I get this right 4-7 years from now.
