In most Gorean cities it is illegal to offer an unbranded woman in a public sale
In most Gorean cities it is illegal to offer an unbranded woman in a public sale. This is presumably in deference to the delicacy and sensibilities of free women.
The brand draws a cataclysmic gulf between the Gorean free woman, secure in her arrogance, beauty and caste rights, and the stripped, nameless, rightless slaves, suitably vended as the mere lovely beasts they are in the flesh markets of this primitive, gorgeous world.
Unbranded women, of course, may be sold privately, for example, as fresh captures to slavers or, say, to men who have speculated that they might find them of interest.
