Long ago, before our time, before Olympus and the gods, Titans ruled the world. Led by Kronos, a force so evil he devoured his own children. But three of his sons escaped. Zeus, Hades and Poseidon. They destroyed Kronos and banished his remains to the depths of Tartarus. But, Kronos is fated to rise again, to exact his vengeance on Olympus, and the world. Only one half-blood child of the three eldest gods can defeat him. This child shall be our salvation, or the cause of our destruction.
