The idea is that the adventuring party, freshly escaped from a slaver's vessel, will find themselves in the desert city of Blackwind. Having completed a few quests around the city, they'll be called upon (depending on how they've acted) by one of three powerful individuals who are looking for help in a growing power struggle - each one of them is hoping to become the Grand Vizier.
And then, since it's the natural thing to do and also because of New Vegas, I thought the adventurers could also decide to seize power themselves as a Council of Viziers and rule as one.
The problem is that it doesn't feel earned right now, particularly the last part; it isn't really a serious, in-depth city adventure, and so much of the content is about wandering out into the desert and mucking about with quests and dungeons. The player party is still finding its feet in Blackwind and discovering wacky new stuff, and then quite suddenly it's dragged into More Important Things.
So I'm wondering whether I try to fix it by pacing out the main plot more slowly, to invest the player further in the politics, or if I try and keep it simple and take out the Wild Card option, since it's too abrupt and jarring.
