@Gingerlily HM. It was surprising because my character - Theodore, a Crone Storm Crow - wasn't political by nature and because the sphere itself was basically unmanned; we had a constantly rotating staff roster who joined and immediately went inactive or did very little while they were there. Rudderless like that, the sphere still flourished.
What made it work was the presence of several really, really good roleplayers spread across the Covenants. Laibah (played by @EmmahSue) joined the Carthians and turned them from a distracted irrelevance into a dominant force, Moritz played an excellent polarizing bad guy Bishop/Prince, Magnus was great in the Invictus, etc. We had a lot of very talented people who went on afterwards to make games of their own all pouring time into the volatile political environment, all player-driven and unplanned.
The main reason I still look back and appreciate it all this time later is that it proves - at least in my mind - that although systems and administrative support matter, it is doable for fluid politics to evolve if there's a strong drive of involved players behind it.
It also shows the importance of both having great people in a game, as sometimes a single really good proactive roleplayer was enough to incentivize and attract others to join their sphere of influence.
