God of War: Chains of Olympus Set halfway through Kratos' ten years servitude to the Gods, Chains of Olympus begins with Kratos being dispatched to the city of Attica to help defend it from the invading Persian army. Soon after his arrival, the Spartan spots a basilisk climbing over the city walls and gives chase. During his chase, Kratos confronts the Persian King inside the city and kills him. Taking the King's power to summon the Efreet, he then encounters the basilisk and kills it. After defeating the basilisk, he witnesses the sun fall from the sky, plunging the world in darkness. Following the dim remaining light on the horizon, Kratos fights his way through the city of Marathon, along the way encountering the black fog of Morpheus, which now covers the land in darkness. God of War: Ghost of Sparta The Oracle foretold that the demise of Olympus would come not from the Titans; but by a Marked Warrior, a mortal. The Olympian Gods Zeus and Ares believed this warrior to be Deimos, brother of Kratos, due to his strange birthmarks. Ares sieges a village of Sparta and interrupts the childhood training of Kratos and Deimos, with Athena on hand to watch over him, and kidnaps Deimos. Kratos attempts to stop Ares but is swept aside and scarred across his right eye by the violent Olympian. Ares prepares to kill the young Kratos for attacking him. Athena stops Ares and tells him they only came for the Marked Warrior, not to take the boy's life. Taken to the Domain of Death, Deimos is imprisoned and tortured by the God of Death, Thanatos.
