After it is discovered that Lanik is a radical regenerative, Lanik's father must essentially banish him from the kingdom, so as to avoid sending him to the "pens", a place where radical regeneratives are kept in order to harvest their body parts; exile also functions to get Lanik out of the eye of the Mueller public, as well as to prevent harm from coming to Lanik's supposed younger brother Dinte. The banishment comes in the form of sending Lanik as an emissary and spy to the Nkumai, a rival nation. Due to his radical regenerative body, Lanik has grown breasts, which makes him appear to be a woman. Using this subterfuge, he poses as an ambassador from the matriarchal nation of Bird in order to discover what the Nkumai are trading in exchange for their abundant metals, which have allowed them to dominate their region militarily.
