Waters Of Babylon Prequel

What happened to the city that John calls the Place of the Gods? Write a prequel, a story of the events that led up to "By the Waters of Babylon." You might write your story from the first-person point of view of the man John finds "sitting looking out over the city," or you might write the story in the form of the man's last journal entries. Your response must be two pages long. You need to write your response on a separate sheet of paper.
