(Last ask from me for the night) Now that I saw that whole bit about Sugar being inspired by Babylonian mythology, I'm starting to think that my theory that the placement of each Gem's respective gem corresponding to Sephiroth (Kabbalah, tree of life) may not be too far off the mark.
I’d wager there’s a good chance that the Sephirot played some role in the concept of the gem placements and whatnot. As we’ve established, Babylonian mythology was definitely an influence so anything that may branch off of that could certainly be referenced.
I think it may be a blending of different mythologies and idealogies, along with original concepts. Like, I’d be really surprised if the gem placements don’t have something to do with chakras but I could definitely see them also being influenced by other mythologies. Making it very intricate and not something you can point to one concept and say “this is what it is”, y’know?
As a side note, I’ve always wondered about how Gems may be related to the Jewish folklore of the golem, which are magically created beings of inanimate matter. Golems are present in Babylonian mysticism and if that’s a major influence it seems possible some inspiration was taken from the concept.
