I'm going to skip line one 'cause we all know it's meaning.

Okay, “To storm or fire, the world must fall” must talk about the boys. At first, I was certain that storm meant Jason, but then again Percy can summon hurricanes, tsunamis, etc. I kind of felt dumb not to think that fire could have meant Frank until Leo mentioned it. When I read the second part, I literally thought the world. But Gaea is the world.

The line “An oath to keep with a final breath.” is the hardest line to interpret, as it's content was barely mentioned. The oath part is making me think that in House of Hades, or the final Heroes of Olympus book that someone declared this oath, and they need to keep till the end of their life. For some reason, this really makes me think of Frank, since that stick depends his life, and this oath I guess depends on whoever's life.
