See my post above about the sect. Another example would be a local magistrate. I have the power structure mapped out. I know what a county magistrates role is, what a district magistrates role is, what a prefectural magistrates role is. They enforce laws, collect taxes, and promote farming. One of their chief functions is handling bandits through their sheriffs (but there are rival power structures they need to deal with as well). Because they serve the empire they are technically supposed to arrest martial heroes but they often can’t because they lack adequate resources to deal with someone that powerful. I also map out all the magistrates in each region where I can. For example I have a prefecture where each district I made an entry for the magistrate (county level magistrates were too numerous to individually make entries for: at least for me, though I do have many of them as well). I also have a chart with each of them on it showing who their sherif is, who the resident patrolling inspector is, how many men each OBS has; and chart shows which magistrate is loyal, bribed (by whom), etc. same with sheriffs and patrolling inspectors. I also have tracked politics to know what tensions and conflicts create problems for the magistrate. This all helps feed into how I play that magistrate (or the sheriff) when he comes up in play. Players belonging to the 87 Killers, going before a magistrate who is bribed by Lady 87, will be more likely to be released and not charged with a crime. Stuff like that.
