MegaTraveller Imperial Encyclopedia indicates that a duke is "associated with a subsector or sector," while a count is "associated with two or three worlds within a subsector." If, for the sake of argument, a given sector is ruled by a duke, is it then appropriate for subsectors to be ruled by counts; or are there gradations of duchies? Would it make more sense to introduce a new level of nobility, a prince(ss), to hold title over an entire sector?
What are the major divisions (Department/Ministry level) of the Imperial government? State, Defense, Treasury, Interior, Commerce... what? Is the sector bureaucracy answerable exclusively to the duke, or is it considered part of the larger Imperial government? Sure, the duke rules in the name and at the pleasure of the Emperor, but what happens at the interfaces between the duke's organization and the Emperor's? Or between the duke's and a subsector-ruling count's?
