The Second Great Prophecy

From Rachel Elizabeth Dare's prophecy, I speculate three of the seven half bloods that shall answer the call.

Jason Grace: Son of Zeus

Piper McLean: Daughter of Aphrodite

Leo Valdez: Son of Hepheastus

And perhaps either Percy Jackson, son of Poseidon or Annabeth Chase, daughter of Ahena for the greek part of the prophecy. For those of you who don't know, the prophecy is as follows:

" seven halfbloods shall answer the call:

to storm orfire the world must fall:

an oath to keep with a final breath:

and foes bear arms to the doors of death"
