I agree with some things and disagree with others. I agree that the 7 that answer the call will be the 7 that ultimately defeat Gaea in the end. However, Reyna said that they would need an army to retake the Doors of Death and that Camp Jupiter didnt have enough troops. If only there was another camp full of powerful individuals that are also full half-bloods...oh wait.

Anyway, the oath line I believe is about Chiron. In The Lost Hero, he said he was planning on retiring after Kronos was defeated. Then all this stuff with Gaea happened and now he cant. He also seems to be hiding something that he said he couldnt talk about,

The storm or fire could be Percy/Jason and Leo/Frank but I dont really know about that one. The world however I do believe is Gaea. And the foes could simply be the forces of Gaea vs the forces of Camp Half-Blood/Jupiter. I mean they are foes after all.

As far as your plot outline goes, if Reyna went with them to Rome, the camp would be completely without a leader as Percy would be going to Rome also. Also, what's Rachel doing there. I mean I know she is Camp Half-Blood's oracle, but she has school and stuff.
