text: Plot During Kratos' ten years of service to the Olympian god Ares, 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 Morpheus covering 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 slumber, Athena tasks Kratos to find Helios, return him to the sky, and break Morpheus’ grasp on the world. The Spartan eventually locates Helios' sister, Eos, who tells Kratos that the Titan Atlas has abducted her brother. Eos advises Kratos to seek the Primordial Fires, which he uses to awaken the fire steeds of Helios. The steeds take the Spartan to the Underworld, where he has two encounters with Charon at the River Styx. Although Charon initially defeats Kratos and banishes him to Tartarus, the Spartan returns with the Gauntlet of Zeus and destroys the ferryman.
