User blog:Ohiogal07/To Storm or Fire the World MUST fall

Seven shall go to answer the call,

To storm or fire the world must fall,

An oath to keep with a final breath,

And foes bear arms to the Doors of Death.

What do you think this means? Storm obviously means Jason and fire means Leo. What oath do you think it means? Thalia's oath to never fall in love? Please, share your thoughts.
