But otherwise as many in the comments are saying, that is some real "How you say you didn't read The Bible and hate Christianity without reading The Bible and hate Christianity" vibes.
I can get it's your story and you do whatever you want with it but holy shit, can people stop with the "Heaven Bad, Hell Good" schtick unless you are basically melding Hell with multiple other Netherworlds/Underworlds from different myths at once(And I mean actually incorporating them on both ends)? It just makes you look like a dumbass.
To be fair, In Judiasm, Lilith DID come first before Eve... the problem is that it's ONLY in Judiasm and the problem is there's no melding of all 3 at once, just primarily Christianity.
It doesn't help that the interpretation of Lilith being "not that evil" ultimately came from the "times" reason she was kicked out of the Garden of Eden(aka because she wanted to be on top... but this was like in the 1500s) but then ignores she becomes a literal demon whose as bad as Lucifer and unrepentant as fuck.
But as everyone else has been saying, they don't even mention God or Satan, just "The Elders of Heaven" which what the fuck does that mean?!
