From the introduction:
Recently captured by slavers, you are in the hold of a slave ship headed for a slave market on the coast of the Black Kingdoms, facing a grim and uncertain future. But your fate is about to change. The slavers, led by their despicable Captain Kahero, have a prize... an Aquilonian noblewoman named Delia, captured alongside you. She will fetch a noble's bounty in Kush, and wants none of it.
