Plot summary
The eight survivors of the Nine Magicians of Zaar, whose colleague Adamancus was killed in the previous volume, cloak their Rmoahal henchmen in invisibility, enabling them to capture their nemesis Thongor. The Rmoahal take him to their castle to turn him over to their masters. He escapes into its catacombs where he destroys an ancient worm god, but is retaken by the Zaarians. Mardanax of Zaar then flies him on a pterodactyl to the city of magicians.

Thongor's ally, the exiled Rmoahal prince Shangoth, infiltrates the city to rescue him. The two manage to turn the tables on the magicians, reflecting their own spells against them. Only Mardanax escapes the slaughter.

The book includes a frontispiece map by the author of part of Lemuria.

Setting
The Thongor series is Carter's premier entry in the Sword & Sorcery genre, representing a tribute to both the Conan series of Robert E. Howard and the Barsoom novels of Edgar Rice Burroughs. He pictures the lost continent of Lemuria as a prehistoric kingdom located in the Pacific Ocean during the Ice Age, where Mesozoic wildlife persisted after the cataclysm wiped them out elsewhere. An intelligent reptilian humanoid race descended from dinosaur reigned supreme as the dominant life form but was partially supplanted by humanity as the continent was colonized by fauna from outside Lemuria. Humans have gradually thrown off their subjection by the older civilization. Culturally, Lemuria is a mixture of civilization and barbarism but overall is precociously advanced over the outside world, boasting a magic-based technology that includes even flying machines. The Thongor books relate the struggle of the titular hero to unite the humans of Lemuria into a single empire and complete the overthrow of the "dragon kings".

Reception
Robert M. Price writes "[t]he Lemurian books pulse with a color and vitality that we miss in many of Lin Carter's later works. ... Yet to his relative inexperience we may also lay the blame for certain inconsistencies and failures to reckon with the implications of what he has written." Among these he notes "Thongor eating dates from the East as if he were in Europe" and "hail[ing] from [Lemuria's] wintry North," when, with the continent "south of the Equator, it would get hotter the further north you went!"

The novel was also reviewed by Alma Jo Williams in Science Fiction & Fantasy Book Review, November 1979, and Richard P. Brisson in Sword & Fantasy no. 8, October 2006.
