Gorean mythology has an origin story for the institution of slavery. Legend states that there was once a great war between the men and women of Gor. The reasons for the war are not stated in the books. But, the men defeated the women and won the war. The Priest-Kings then feared that all of the women would be killed and they did not want those results to occur. To protect the women, the Priest-Kings made all of them beautiful so that men would find them appealing. But, this beauty did not come without a price. The Priest-Kings also decreed that women would always be the slaves of men.

One depiction of this myth, on a shield, shows a group of satyrs capturing a group of Amazons. This directly indicates the obvious Greek origins of some of Gor. This myth also echoes the Amazonomachy of Greek mythology. An Amazonomachy is a great battle between the Amazons and the male Greeks. Ultimately, the Amazons lose the battle and are enslaved by the Greeks.

The Curulean of Ar, its great auction block, is ornately carved and this carving is of the figures of nine slave girls. They represent the legendary first nine girls that were ever enslaved when Ar was but a small village many thousands of years ago. As the girls have rope collars, it is claimed that Ar did possess the skills of metal working at that time. It is also part of the legend that these slaves were forced to breed sons for the men of Ar. This seems unusual in that Goreans rarely breed with their slaves as the offspring of a slave is commonly considered a slave.
