What relationship does the Influence Character have to the rest of the Objective Characters?
The Influence Character (IC) is tied to one of four characteristics in the Objective Story (OS): the OS problem, OS solution, OS focus, or the OS direction. The Main Character (MC) is also tied to this quad of elements. Determining which one is a little beyond the scope of this email, but suffice it to say that these are the ONLY elements that are required to tie the MC and IC to the OS. Traditionally, however, authors tend to make their MC and IC a little more integrated into the "big picture" Objective Story.
