Acceptance brand, (noun); a tiny brand in the form of spreading bosk horns for any wishing to do business with the Wagon Peoples that allows their passage over the plains; the stigma connected with this brand is that any approaching the wagons, does so as slaves.
The street was lined by throngs of Tuchuks and slaves. Among them, too, were soothsayers and haruspexes, and singers and musicians, and, here and there, small peddlers and merchants, of various cities, for such are occasionally permitted by the Tuchuks, who crave their wares, to approach the wagons. Each of these, I was later to learn, wore on his forearm a tiny brand, in the form of spreading bask horns, which guaranteed his passage, at certain seasons, across the plains of the Wagon Peoples. The difficulty, of course is in first obtaining the brand. If, in the case of a singer, the song is rejected, or in the case of a merchant, his merchandise is rejected, he is slain out of hand. This acceptance brand, of course, carries with it a certain stain of ignominy, suggesting that those who approach the wagons do as slaves.
