During Kratos' ten years of service to the Olympian Gods, he is sent to 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.
