We know that the world "must fall" to either "storm or fire". As usually, the prophecy could have multiple meanings. For instance the world could literally fall as in the heroes fail and Gaea takes over and kills all humans, demigods, etc. The world could also refer to Gaea, meaning she will fall back to sleep because of either "storm" or "fire". In my opinion "storm" and "fire" are metaphors. "Fire" could refer to a lot of things; Leo, Frank, "the Mark of Athena burning through Rome", or something else. "Storm" could be referring to a lot of things too; Jason, Percy, Porphryion's fall, etc. The thing is, I think the series is going to have a happy ending (as Riordan books usually do), so I believe in Gaea's fall.
