the effect of a process
One way to measure the relationship of items in a quad is to classify him as Potential, Resistance, Current, and Power (or Outcome). In this manner, we can see how dramatic components operate on each other over the course of the story. Power simply means the effect of a process. When a dramatic Power exists it does not necessarily create change. Rather, until it is applied for the necessary period of time by Current, the Power will have not have the impact sufficient to affect change. So in a quad, assigning one of the items as the Power does not mean it will alter the course of the story. Instead, it might function to direct effort by providing a specific target. This is a useful tool for Authors since it allows for the subtle relationship of unused, inferred, threatened, or anticipated dramatic interactions that shape the fabric of a story in ways other than conflict.
