List of Percy Jackson and the Olympians characters
The Oracle of Delphi: Apollo's Oracle of Delphi used to live in the mummified remains of its host until its spirit was transferred to Rachel Elizabeth Dare in The Last Olympian. The Oracle's spirit originally passed from the deceased oracle to a newly chosen oracle; however, at the end of the second world war, the oracle gave a Great Prophecy predicting a child of the Big Three (Zeus, Posiedon, and Hades) would determine whether or not the gods would be preserved or destroyed. Using this information, the Big Three entered a pact in which none could continue to sire heroes. In spite of this, Hades bore two young children, Nico di Angelo and Bianca di Angelo. Zeus, fearing that either were the children of the prophecy, destroyed the hotel where the di Angelos lived with his master bolt, killing Maria di Angelo, Hades' lover. In revenge, Hades cursed the Oracle to ensure that the spirit of the Oracle of Delphi would not pass to a new host but be trapped inside the body after the death of its host in hopes that it would soon return to the dust along with its bodily prison. After the Battle of Manhattan in which Hades and Nico successfully assist in the defense of Mount Olympus, Zeus honors the Lord of the Dead. In response to his newfound respect from the other gods, he lifts the curse, allowing the Oracle's spirit to pass on into Rachel Elizabeth Dare, effectively releasing the trapped soul of the last host of the Oracle.
