The ProphecyEdit

Seven half-bloods shall 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.

To the Romans, this is one of the most important prophecies saved from Ancient Rome's downfall. It was salvaged from the Sibylline Books, which are believed to have been burned in the attack on the original Rome. It is carved in the floor of Octavian's temple, as seen in The Son of Neptune.

The Great ProphecyEdit

The Greeks called this the Second Great Prophecy. It was spoken by their Oracle, Rachel Elizabeth Dare, at the end of the last book in the original series: Percy Jackson & the Olympians. They were hoping that this prophecy would not take place until many decades later, but it actually began much sooner than expected.
