the city of Attica to help defend it from the invading Persian army. After successfully killing the Persian King, decimating his army and slaying their pet basilisk, Kratos observes the Sun fall from the sky, plunging the world into darkness. As he fights his way through the city of Marathon, the Spartan witnesses the black fog of the Olympian Morpheus cover the land. He hears a haunting flute melody, which he recognizes as a melody once played by his deceased daughter Calliope. Finding the Temple of Helios, Kratos learns from Athena that Morpheus has caused many of the gods to fall into a deep slumber due to the absence of light. Before she succumbs to the slumber, Athena tasks Kratos to find Helios, return him to the sky, and break Morpheus’ grasp on the world.

While he was distracted by his reunion with Calliope, Persephone's ally Atlas was using the power of the kidnapped Helios to destroy the Pillar of the World, which would also end Olympus. As the resulting destruction of the Pillar will also cause the souls of the Underworld, including Calliope, to be lost, Kratos abandons his daughter forever in order to save her life. Taking back his power, Kratos battles Persephone and Atlas, binding the Titan to the Pillar before slaying the goddess. Although victorious, he is warned by a dying Persephone that his suffering will never end. Atlas, forced to hold the weight of world on his shoulders for eternity, also warns Kratos that he will eventually regret helping the
