On a thematic level, all of the concerns are “connected” to the goal by their nature of being a “different version of the same thing” in their respective Domains. But I wouldn’t think of them as “Goals” …
What I mean by that is if your OS Concern/Goal = Obtaining
then your MC Concern might be Future, IC Subconcious…
They’re the “same” thing… in the same position of the Concern Quad, just seen through a different lens.
Basically, with the PLOT of your story the OS Concern be always be the Goal as far as Dramatica is concerned.
The only problem I can think of with thinking of any of the other throughlines having a “goal” is that there is no real “target” to reach in an objective sense. It’s just the nature of each throughline:
The MC is more of a subjective, mental process kinda thing. It’s tied to the audience… the “eyes” of the audience. The Audience doesn’t really have a “goal,” so neither does the MC.
The IC is more about the MC subjectively looking at the objective IC and what that influence looks like.
And the RS is more about describing the nature of the forces at play between everything. The other 3 Domains’s concerns really just help to track their throughline’s arcs.
