What is a prophecy?

You would be surprised at how many people do not know what a prophecy is.

Prophecies are predictions of the future, usually a prophecy would inform a person of a major event that is coming up later. Prophecies generally but not always, rhyme and because of that it makes it difficult for a person to decipher the meaning. Often times prophecies are thought to bring misfortune to the "victims" throughout the rhyme.

The most common way of a prophecy being told is through the Oracle of Delphi, who changes from host to host, telling demigods of important prophecies. It was the Oracle of Delphi who spoke of the first great prophecy, and because of that, Hades had placed a curse on her, trapping the Oracle of Delphi inside that certain host for a long time. Now, the curse has been lifted and the current host of the Oracle of Delphi is Rachel Elizabeth Dare, a friend of Percy.
