I make no pronouncements on these matters, but report them as I find them.
Arrive at your own conclusions.
I wish you well,
The Priest-Kings of Gor, who served as the divinities of this rude planet, inspired little but awe, and occasionally fear. Men lived in a truce with the Priest-Kings, keeping their laws and festivals, making the required sacrifices and libations, but, on the whole, forgetting about them as much as possible.

"Occasionally on Gor we destroy a city, selecting it by means of a random selection device. This teaches the lower orders the might of Priest-Kings and encourages them to keep our laws."
Priest-Kings of Gor Book 3 Page 123
"Nonsense," said Misk. "But perhaps I shall show you the Scanning Room someday. We have four hundred Priest-Kings who operate the scanners, and we are accordingly well informed. For example, if there is a violation of our weapons laws we usually, sooner or later, discover it and after determining the coordinates put into effect the Flame Death Mechanism."
Priest-Kings of Gor Book 3 Page 125
"But you killed him," I said.
"Of course," said Sarm, "he broke the law of Priest-Kings."
"What right have you to make the law for him?" I asked.
"The right of a higher-order organism to control a lower-order organism," said Sarm. "The same right you have to slaughter the bosk and the tabuk, to feed on the flesh of the tarsk."
Priest-Kings of Gor Book 3 Page 139
On the other hand I had been informed, graciously, by the Muls who manned the portal that it might not be opened by them to release me once I had decided to enter. As they put it, they simply were not permitted to do so. It was the law of Priest-Kings.
Priest-Kings of Gor Book 3 Page 187
The Priest-Kings who had served him had, on the whole at least, believed that what they were doing was required by the laws of the Nest, but now with Sarm's disappearance Misk, though only Fifth Born, acceded to the title of highest born, and it was to him now, according to the same laws of the Nest, that their allegiance was now owed.

"If you should regain your power," I asked, "what do you propose to do with it? Will you still set forth the law in certain matters for men?"
"Undoubtedly," said Misk.
Priest-Kings of Gor Book 3 Pages 313 - 314
And if I should find the object - why should I not myself destroy it, and destroy thereby the race of Priest-Kings, giving this world to my own kind, to men, to do with as they pleased, unrestricted by the laws and decrees of Priest-Kings that so limited their development, their technology?
Nomads of Gor Book 4 Page 7
Some of the goods, however, were surely of Earth. Among them was a high-powered rifle with telescopic sights. To possess such a weapon, of course, on Gor was a capital offense, it being a violation of the weapon laws of Priest-Kings.

If the marooned Kurii abided by the weapon and technology laws of Priest-Kings, they, like men, another life form, were permitted to survive.
. . .
Most lived in ships, the steel wolves of space, their instincts bridled, to some extent, by Ship Loyalty, Ship Law.
Marauders of Gor Book 9 Page 92
In the laws of Priest-Kings it was up to such species, those of Kurii and men, to resolve their differences in their own way.
Marauders of Gor Book 9 Page 175
All in all, I expected the invasion of the south was, at this point, primarily a probe. If it was successful, the Priest-Kings, to preserve men on the planet might be forced to intervene, thus breaking their own laws. If the Priest-Kings did not do this, perhaps for reasons of pride, their laws having been given, then, in effect, Gor might become a Kur world, in which, given local allies, the Priest-Kings might finally be isolated and destroyed.
Marauders of Gor Book 9 Page 176
If Kurii native to Gor could, within the laws of Priest-Kings, not violating technology restrictions, much advance the Kurii cause on the planet, those on the ships had little to lose and much to gain.
Marauders of Gor Book 9 Pages 216 - 217
Native Kurii, bred from ship's survivors over centuries, would not, it seemed, if limited to the primitive weapons permitted men, be capable of conquering Gor, isolating the Priest-Kings in the Sardar, until they could be destroyed, or, alternatively, be used to lure the Priest-Kings into a position where they would be forced to betray their own weapons laws, arming men, which would be dangerous, or utilizing their own significant technology, thereby, perhaps, revealing the nature, location and extent of their power, information that might then be exploited at a later date by the strategists of the steel worlds.
Marauders of Gor Book 9 Page 267
A message may be conveyed by means of drum stations for hundreds of pasangs in less than an Ahn. Needless to say Bila Huruma had adopted and improved this device and it had played, and continued to play, its role in the effectiveness of his military machine and in the efficiency of the administration of his Ubarate. As a communication device it was clearly superior to the smoke and beacon ciphers of the north. There was, as far as I knew, nothing on Gor to compare with it except, of course, the advanced technological equipment at the disposal of the Priest-Kings and Kurii, equipment of a sort generally forbidden, in the weapons and communication laws, to most Gorean humans.
Explorers of Gor Book 13 Page 219
(speaking of Kurii) Priest-Kings, on the whole, tend to ignore such beasts. They are permitted to live as they will, where they may, on Gor, following even their ancient laws and customs, providing these do not violate the Weapons Laws and Technology Restrictions.
Savages of Gor Book 17 Page 34
They intend, perhaps, failing success in outward aggression, to subvert our world, city by city, or to form a league of cities, that may become dominant among our states. This might be accomplished, presumably, within the weapon laws and technological limitations imposed upon Gorean humans by Priest-Kings, for whatever might be their purposes.
Kajira of Gor Book 19 Page 385
In many respects Priest-Kings seem to be tolerant and defensive creatures. For example, they permit native beasts on Gor, marooned beasts, and such, provided such obey, their laws, particularly with respect to weaponry and technology.
Kajira of Gor Book 19 Page 389
From the testimony of Sheila, and other sources which seemed to corroborate it, we gathered that the Kurii might now be turning to the patient stratagems of piecemeal subversion, the control of cities and their eventual linkages in networks of power, to win a world by means theoretically within the laws and decrees of Priest-Kings.

The common sulfur match, on the other hand, so common on Earth, I have never met with on Gor. The chemistry involved in such a device, interestingly enough, is forbidden on Gor. It is regarded as constituting a violation of the Weapons Laws imposed on Goreans by Priest-Kings. This is not as farfetched as it might sound at first. Sulfur, for example, is one of the primary ingredients in the composition of gunpowder.
Mercenaries of Gor Book 21 Page 395
Too, the tarnsman retains something of the glamour which on Earth attached to the horseman, particularly so as the technology laws of the Priest-Kings, remote, mysterious masters of Gor, preclude the mechanization of transportation.
Renegades of Gor Book 23 Pages 138 - 139
"Do you believe in Priest-Kings?" asked Marcus.
"Certainly," I said.
"I do not," he said.
"As you will," I said.
"But how are we to explain the Weapons Laws, the Flame Death?" he asked.
"That would seem to be your problem, not mine," I said, "as I accept their existence."
"Something exists," he said, "but they are not Priest-Kings."
"That is an interesting thought," I said.
"It is only that they possess the power of Priest-Kings!" he said.
"That is a second interesting thought," I said. "But if they possess the power of Priest-Kings, why not call them Priest-Kings?"
"Do you think they would mind, if I did not?" he asked, somewhat apprehensively.
"Probably not," I said. Indeed, provided men kept their laws the Priest-Kings were content to let them do much what they wished. The major concern of Priest-Kings with men, it seemed, was to have as little to do with them as possible. That had always seemed to me understandable.
"You have loosed lightning," said Portus Canio. "Have you released such lightning before?"
"Several times," said Mirus, "here and there, and in hunting."
"Then," said Portus Canio, "the Priest-Kings will know of it."
"This is the world of the Priest-Kings," said a man. "They have forbidden men such things."
"There are no Priest-Kings," said Mirus. "If there were Priest-Kings they would have acted, to enforce their so-called laws. But there are no Priest-Kings, as we see, and the laws have a simple explanation, namely, an attempt to preclude an ever-increasing efficiency of engineered carnage."
"They concern themselves with the keeping of their laws," said a man.
"Beware the Priest-Kings," said one of the men.
Mirus, and several of those with him, smiled.
"Have you ever seen a Priest-King?" asked one of the strangers, of the fellow who had spoken.
"No," said the man.
"Have you ever seen any evidence of the enforcement of their laws?" asked another of the strangers.
"I have heard of such things," averred the man.
"But have you ever seen any evidence of such a thing?" he was asked.
"No," said the man.
"It does not exist," he was told.
Human beings tend to assume that the Priest-Kings are rather like themselves, that they are human, or, at least, humanoid. Perhaps their vanity prompts such a speculation. Kurii, too, incidentally, assume that the Priest-Kings must be somehow akin to them. Surely the terror of their ships and the accuracy of their weaponry suggests that. But let us not waste fruitless speculation on this matter. Whatever may be the nature of the Priest-Kings, it is clear, as does not seem to be the case with many gods, that they exist.
The Flame Death, with which they commonly enforce their laws, if nothing else, mitigates against agnosticism in this matter.
One thing about the Priest-Kings puzzles the Kurii, and that is why this mysterious life form seldom behaves otherwise than defensively. They will react sharply if not inevitably to border crossings, but they will not pursue the rebuffed invaders; they will not seek them out, and destroy them in their lairs.
Indeed, Priest-Kings are tolerant of the presence of Kurii on Gor itself, provided they respect their technology and weapon laws.
"I wish I had a rifle," said Pertinax.
"It is better that you do not," I said. "If you possessed such a weapon, you would be in violation of the weapon laws of Priest-Kings, and liable to the flame death."
"Surely there would be an inquiry, a trial, or such," he said.
"No," I said.
"You have heard of the Flame Death of the Priest-Kings?" asked the first beast of Tyrtaios.
"I have heard of it," said Tyrtaios, "but have not seen it."
"I have seen it once," said the beast, "when a fellow of mine, brandishing a forbidden weapon, one forbidden by the laws of Priest-Kings, was suddenly torn away from me, literally from my side, in a burst of light, of flesh of blood, and ash. The stones on which he had stood had melted."
"They are Priest-Kings," I said. "I have heard of them."
"They have enacted laws, weapon laws, communication laws, and such," said Kurik, "that are enforced with severity that no other form of life, Kur or human, or other, may reduce, sicken, or ruin their world."
"Why do not the Kurii," I asked, "if they are so ambitious, violent, and powerful, if this world is not yet available to them, seize Earth?"
"Priest-Kings," said Kurik, "shelter Earth. Who would place at the disposal of an enemy the resources of a planet, who would grant them an island, a platform, from which, in time, to launch a great arrack, a mighty armada, against them?"
"How is it," I asked, "that Priest-Kings have permitted humans on their world?"
"Gods," said Kurik, "have their curiosities, their hobbies, their passions, and interests. Gor has been stocked with thousands of life forms from throughout the galaxy. Humans were brought to Gor with many other forms of life. Surely humans are an interesting form of life."
"And Priest-Kings," I said, "condone humans, and even Kurii, on Gor?"
"Provided the laws are kept," said Kurik.
