I am, for the first time ever, running a Pathfinder campaign. I'd prefer to start with a premade campaign or adventure path that I can adapt to my story, the specific details of which are extremely vague – the first couple of levels, they're interacting with a coup to gain control of a city that must end with them having a certain artifact. (I'm worried about missbalancing, etc.) These are PCs without any particular sense of morals. Any suggestions?
Clarification: the city has an existing, working, stable gov't. There is a coup to overthrow that gov't (or preferably, to take mental control of the mayor).
RESCOPING: I am NOT looking for adventure paths, I am looking for self-contained modules of the form "go to X, do Y" (e.g, go take steal $OBJECT from goblin hoard at $OUTSKIRTS) that can be plugged into any adventure with minimal modifications. The specific type I'm looking is either in a city, or next to one.
