These agents of darkness can be found explained in a more modern story by Shakespeare. In the story Macbeth, the main characters are the Three Witches who are described as the “The weyward Sisters,” hand in hand, Posters of the Sea (Chaos/Darkness) and Land. The Three Witches represent darkness, chaos, and conflict, while their role is as agents and witnesses.

Their presence communicates treason and impending doom. The witches’ lines in the first act: “Fair is foul, and foul is fair: Hover through the fog and filthy air” are often said to set the tone for the remainder of the play by establishing a sense of moral confusion. he play is filled with situations in which evil is depicted as good, while good is rendered evil.
