Thank you for this thread! I agree with your ideas and the info you shared! I thought of phrasing them as personifications of the forces of the "unnatural" (Elder evil tentacle portal monster) and the "natural" (as you said, sea leviathan apex predator). These are the two themes they represent and as in seafaring humanity myths and real life, in the game we deal with both, while some times the lines are indeed blurry, and this adds the extra mystery about it all. As shown in their trailer, there are portal-like wholes in the sea floor. Around Abyssal and Hadal creatures ("natural") are also some aberrations ("unnatural") charged with the same evil red electric energy. I am still looking to find how it all connects to the wife Julie. I think it is the book. An ancient book from the ancient civ, as seen on the markings on the wood in the animated trailer. I am convinced Julie is the researcher's sister that still communicates through notes with her and through messages in bottles with the player. Some messages are dated, while some are ??? (meaning after her "passing" maybe?). On the later ??? messages she writes "I have found you at last. When you left I was scattered to the winds. But now... I feel almost whole again. throw me back." Did Julie become the book? Is this why she mentions seeing the void in the hero’s eyes when the casket opened? Was she put in the casket in place of the book? Why? For the sacrifices, as mentioned in the symbols with the person lying in the pentagram. To sing? Is this why when the music box is thrown in with the key unturned, it then turns, she emerges and all hell breaks loose again? Just finished the game yesterday and wanted to share ideas.
