The story begins with Kratos, who is imprisoned, chained, and tormented by the Furies for breaking his blood oath to Ares. The Fury Megaera tortures Kratos, but he manages to break free. Chasing her through the prison, he discovers that the prison itself is Aegaeon the Hecatonchires, the first traitor of the Furies who had broken a blood oath to Zeus; he was turned into the Prison of the Damned as punishment.[29] Overcoming an illusion created by the Fury Tisiphone and her familiar Daemon, Kratos finds and kills Megaera, retrieving the Amulet of Uroborus, which the Furies had confiscated from him when he was imprisoned.
