For example, the wizards generally don't want one powerful figure ruling them all and this became even more true after Brankaresh's treachery. So the wizards watch each other and Brankaresh's successor as Chief Wizard, Abstar, ensures his fellow wizards are answerable to him but at the same time he is answerable to them. So far this approach is working and he hasn't upset anybody much. This is the sign of a wizard likely to stay alive long enough to collect some kind of pension later on!
So who carries out good (or bad) governance in your stories? Who are they answerable to? What happens if the system goes wrong?
