Throughout the novel, Wang uses multiple scenarios to demonstrate that the art of storytelling can both reveal the truth and serve as propaganda, depending upon the intentions of the storyteller. Thus, the narrative embarks upon a philosophical exploration of the very nature of truth, questioning whether truth is subjective or objective and whether storytellers have an obligation to tell the truth. From the very beginning, storytelling has special value in the world of The Sword of Kaigen, for the art is recognized and enshrined within the structure of the culture itself. This philosophy is apparent in the existence of the jaseli, a social caste of storytellers, historians, and political advisors who enjoy an elevated status and are ranked just below the religious leaders and on an equal footing with the ruling caste. When Misaki wishes to learn more about what is happening with the Kaigenese military who arrive in Takayubi, she does not speak with a soldier but with the apprentice jaseli of the group, flattering him and playing on his vanity as a valuable advisor in order to gain essential information.

With the power of storytelling thus firmly established, the author then develops the multifaceted purposes of that storytelling within the Kaigenese world.
