This is pretty much just off the top of my head, but I have read most of the OP theory about everything being tied to the moon, but doesn't it all tying back to Atlantis seem a bit more plausible? I mean ancient civilization lost in history with two of the ancient weapons centering around the ocean, with Posiedon being a mermaid and the legendary ship builders being passed down through Tom's lineage (a fishman)
Atlantis was supposedly a great civilization with highly advanced technology just like the lost civilization described in the polyglyphs and Raftel could possibly be the last stronghold those of Atlantis had left where they could get away from their enemies and record the world's truth.
Also, the moon can still tie in seeing how the moon controls tides (ties back into OP's ocean theme)
Anyway what do u think?
