"Khor the Wanderer, men call me," he said. "From the land of Crete in the Upper Sea, I come. For more than a hundred moons have I traveled east. And now I have reached this land of Mu, called by the travelers the home of the gods."
Khor's world would seem to be vaguely like Howard's Hyborian Age in that it's heavily based on aspects of the ancient world of Earth, though mythologized and including many fantastical elements. Khor's Crete, for example, would seem to be some analog of the Bronze Age Minoans, given by his use of a double-headed axe in battle, said weapon being an important symbol of that ancient civilization. On the other hand, the reader should no more mistake Khor's Crete for the real Crete than he should Conan's Cimmeria for the real one. Kummer, like Howard, is using the names and broad details of the ancient world as a foundation on which he builds his fantasy.
Shortly after arriving on Mu, Khor observes "a slender dark-haired young man clad in a blue mantle" attempting to fend off an attack by "four warriors in gleaming gilded armor, squat swarthy men, their faces aglow with fierce exultation."
Khor marveled at the skill with which the youth, armed only with a light hunting sword, defended himself against the four flashing blades; yet it was evident that his was a losing battle, that the men in the golden armor were intent upon keeping him occupied until a loss of blood and exhaustion would cause him to drop, an easy victim, at their feet.
It was this latter fact that decided Khor. Brave men, he felt, would fight to kill ... but this wearing out an opponent and then slitting his throat at one's leisure was the work of cowards. Grimly he raised the burnished bronze axe, and, with a shout of encouragement to the man in the blue mantle, sprang from the shadow of the trees.
Khor's attitude is another way in which "Adventure in Lemuria" reminds me of Howard's work. The Cretan wanderer adheres to a rough but honest code of honor of a sort not too different from that of Conan. He saves the youth, who name we learn is Jador, not because he objects to what appears to be banditry but because he disapproves of the way that the four golden-armored men toy with their would-be prey.
Jador thanks Khor for his assistance and reveals that he is the ruler of Zac, "which is part of the great nation of Lemuria ... Mu."
"A prince!" Khor grinned ironically, glancing at the bodies of the gold-clad warriors. "And these ...?"
"Followers of my half-sister, Lalath." The youth's face darkened. "Five years since, when I was still a child, she seized the throne of Zac. Only through the loyalty of my guard was I able to escape. Five years in hiding, I spent, and now, having come of age, I seek to regain my throne, reestablish the worship of Narayama, the true god, in place of blood Molech. Today, accompanied by a few loyal retainers, I came here to await the arrival of those who espouse my cause, peasants, merchants, nobles, all sworn to assemble here during the night, attack the city tomorrow. By mischance we encountered Lalath's warriors ... and the rest you know."
Khor, being an experienced and well-traveled man, tells Jador that "no handful of rebels" will be sufficient to achieve what he intends. The prince, however, is unperturbed and explains that "Narayama the true god shall aid us." He then adds, "When I return to the throne of Zac, you will be rewarded. Thanks and may the gods keep you."
Despite his intention to leave the young man to his doom, Khor cannot abandon Jador. Instead, he joins him in his ascent up a nearby mountain, upon which "lies the secret tomb of [Jador's] ancestors," where he shall pray to Narayama for guidance. The prince takes Khor's change of heart as evidence that the Cretan "must have been sent by the true gods," just as he does the wanderer's suggestion he might could aid him by entering the city alone and "at the appointed hour fall upon the guards of some postern gate, open it to admit your armies" – a plan to which Jador readily agrees.
Of course, things don't go quite as simply as that. Khor is captured before he can execute his plan and he is taken as a prisoner before Lalath, where he is given the choice of joining her or becoming another sacrifice to Molech. It's at this point that the story really takes off and Kummer – and Khor – reveals he has a trick up his sleeve, leading to a fairly satisfying climax. "Adventure in Lemuria" is a brisk, straightforward yarn that held my attention for the entirety of the time I was reading it. Certainly, it doesn't hold a candle to even the lesser entries in, say, the Howardian canon, but it was fun and, when it comes to pulp fantasy, that's not nothing. If you'd like to give it a read yourself, it's been collected, along a number of other similar tales, in Heroes of Atlantis & Lemuria.
