A mystery drew Hercules and Iolaus to the city of Tantalus. There, the bodies of fallen warriors were disappearing from the battlefields. Hercules learned that Ares, the god of war, was to blame. After King Memnos' death, his son Daulin had assumed the throne, Daulin's sister Poena, had taken up arms against him. She believed Daulin had killed their father. Ares had created the entire situation merely to satisfy the appetite of his bloodthirsty hound, Graegus. After leashing the vicious beast, Hercules explained the truth to Daulin and poena, bringing an end to the family war.
