The Saga- One of my favorite episodes was “The Inner Light” because it spanned a whole lifetime in an hour. When I watched it I felt like it ran longer than it did. Same thing for DS9’s “The Visitor”. Both stories were epic, covering a long lifetime. They created the sense of a passage of time and yet they were complete in and of themselves. Create a time-spanning saga. You have 20,000 characters-which is the max for a single post. If it runs over into a second post (like my “Lost Kingdom” story did in August) it is disqualified. Work within the frame available. Good luck!
