Mahars of Pellucidar

Christopher West is an associate of Dr. Kinsley, who has developed a teleportation beam that can also see events taking place 200 miles below the surface. When they see people about to sacrifice a beautiful woman, Christopher obtains a pocket knife and a red fire axe and has himself beamed down to rescue the woman. Due to his unusual weapon, West becomes known as Red Axe among the stone-age human beings of Pellucidar. The story deals with West's efforts to free his new-found friends from the tyranny of the Mahars. The region visited by West is apparently an area of Pellucidar different from that in which Burroughs set his stories, from which the Mahars were driven at the end of the second book in the series, Pellucidar. Evidently there are other locales in which the reptiles are dominant. Therefore West never runs into any of Burrough's human Pellucidarian characters, such as David Innes, Abner Perry, Dian the Beautiful, Ghak the Hairy One, or any of the others.
