I agree with your theory about the world maybe not being Gaia.

I also agree with the theory about storm and fire being Roman and Greek.

I don't understand what you mean about Hazel's mist and Frank's firewood. The prophecy doesn't say anything about those.

Yes, the oath is obviously Leo's oath to Calypso on the river Styx. Plus, while Leo left ogygia, there was a passage that made that clear: As his raft skimmed over the water, taking him back to the mortal world, he understood a line from the Prophecy better – an oath to keep with a final breath. Also Leo asks Calypso for a crystal, he obviously knows that if he put it in the astrolabe, it would take him to ogygia.

I really don't know about anyone dying I think at least one of the seven will die but I really don't know who.

I think Leo is the most obvious death because of the line an oath to keep with a final breath but Riordan will surely do something unexpected so I really don't know.

I think Octavian speaking in Gaia's voice doesn't have much importance. Kind of like Athena saying the Roman must bring me to Annabeth. Athena couldn't really be speaking, the gods couldn't communicate because of their Greek and Roman sides were fighting.
