The main antagonists of the game all feel like the smokescreen of the real big bad evil guy's actual scheme, except it never happens. Something so ridiculous as shackling a Elder Brain to brainwash the world to serve you is so beyond the pale that it seems doomed to fail...all according to plan...
Of course each origin character had their own personal antagonist to contend with too, and I guess they were all at one point going to be much more involved with the central plot.
As it is I feel the plot of the cult is like the Doppelganger plot in the first game if there were no Sarevok, with us instead only dealing with his lieutenants.
