How do the character elements work in each of the throughlines?
I know that there are 64 elements to be distributed among overall characters. However, the Main and Influence characters double up as overall characters, so if you had a main character who was also a protagonist - would you need two sets of elements or would they be the same for that player? Also, how do you go about choosing character elements - can you pick them from anywhere? I have noticed that they are arranged in different patterns for each separate class - is this purely for picking just one element for each throughline to signify their main problem. Does it affect the way you pick elements for the overall characters?
You're right about the Main Character and Influence Character. Each one has a complete set of character elements. These elements describe the POSSIBLE places the problem might be in each of their throughlines, but only the PROBLEM element in each throughline is the cause of conflict in the throughline. So, while you may have your Main Character explore all of the elements while trying to solve his personal problems, only the MC Solution will do.
Both the MC and IC also have Overall Story counterparts (more accurately, the players that represent the MC and IC also represent players in the Overall Story throughline). Therefore, their roles in the OS (and the elements assigned to those characters) give them something to do within the context of the Overall Story. For example, Luke Skywalker--as MC--tries to work out his personal problems and learns to trust his instincts, while he plays protagonist in the Overall Story as a proponent in fighting the Empire.
The different patterns within each class are understandable when you look at how the Dramatica structural model is built. The bottom level is where the elements from which you build your Overall Story characters are found. Unlike the top three levels, however, each item does NOT have its own unique label (e.g. Pursuit and Consider). There is one set (or what we call a "chess set") of 64 unique labels which cover all of the elements for a single Domain/Throughline. Dramatica consists of four Domains and the elements appear within each of these Domains. The DIFFERENCE between the elements of one Domain and another is the arrangement of the elements within the quads. Though a dynamic pair is never split (e.g. Pursuit and Avoidance), it will be paired with different dynamic pairs to make up each quad. The combination of the four elements within each quad is different from domain to domain. These combinations create slightly different contextual "flavors" for the elements which substitute for unique labels. Therefore, Pursuit in a Situation domain is subtly different than Pursuit in an Activity domain because of the shared elements of the quad in which it is found.
Picking elements for MC or IC do not control which elements you assign to their functions in the Overall Story throughline. Build the characters however you'd like to.
