It's nonstop, page-turning action in this fourth and final issue detailing the weirdest war ever witnessed in the Hyborian Age! The White Apemen of Mount Bori join the She-Devil's side against the Arean Invaders, and Martian battles Martian when one bulging-brained attacker is possessed by the ancient serpent god Set and emerges flanked by snake-filled Martian mummies as the all-powerful conqueror, MAR-SET-AHKS!
