dramatic forces that determine the course a story will take
The power of a story is divided between two realms. First is the structure that represents the dramatic potentials that exist in character, plot, and theme at the beginning of a story. Second are the dynamic forces that will act upon the dramatic potentials to change the relationship between characters, change the course of the plot and develop the theme as the story unfolds. In Dramatica, choices between alternative forces such as "Success or Failure" and "Change or Steadfast" determine the dynamics that will act upon a story.
