I see a lot of people interpreting "to storm or fire the world must fall" as having to do with certain demigods. But it might refer to something else. Like the Twelfth Legion Fulminata, "armed with lightning". I couldn't think of much to do with fire, but throughout the series, the Greek side of things have a lot of references with fire: like Prometheus and his fire, Leo and Festus, the mark of Athena burns through Rome, even Greek fire itself.

Another thing I see here is people assuming "foes bear arms to the Doors of Death" referring to both the armies of both Roman and Greek demigods. Foes can refer to two people as easily as it can mean armies.

I think it's far too early to determine "an oath to keep with final breath". It could be any promise from anywhere in the HoO or PJO series or one that was never even mentioned.
