I think the segregation is best seen as a temporary fix, a way to give the both of you footing to lead to further tension and negotiation on the fate of the city.  Muse will have the Old City along with the bulk of our military might under his command, which means he cannot simply be ignored for his position.  At the same time Madder will control a lot of the actual city along with the major areas needed for the city to function.  This means that Muse’s character has to acknowledge her power.<br/><br/>This is the source for great tension.  Each looking to undermine the other, to impose their idea of what is best for the city on the other through more conventional methods.  Muse can’t just rush in and use the military on Madder, because he would essentially destroy the city in doing so.  Madder can’t just use CPI to take over everything because the Old City is a safe haven for Muse’s military force.  So there is footing for the both of you to push and tug against each other.<br/>
