Orc slaves, apparently, were not necessities for purchase. Even if nobles were interested in exotic beauties of different races, this was discretionary consumption, and no one was interested in taking the high-priced bait.

One would still need connections to be able to sell them there. After all, they have specific partners they work with and are not likely to replace them easily.
The most valuable slaves can't sell for high prices, so making a fortune through monopoly is impossible. Even the difficulty of return has instantly increased several-fold. On the contrary, the probability of a loss has begun to rise rapidly.
