"In the fabled land of Onthat lie twin cities of Cathie and Athne - one a city of gold, the other a city of ivory. For generations the cities have been at war, using armies of trained lions and elephants. When Tarzan rescues Valthor, and Athenian, the Ape Man is taken captive by the mad Queen of Cathie - as a pawn to be used in the savage 'games' conducted for her amusement. But Tarzan has some surprises for her!"
