I assume this to mean that the province of Durazzo is to have no sitting Senator, then?

As you yourself mentioned, Efstratios is no longer a Senator of the Byzantine Empire. The people of Durazzo have a right to a new representative. As a formal delegate from Durazzo, and Monomachos' aide, I am finishing the former Senator's term in office until a new senator is elected.

Perhaps Makedonios is simply afraid of being criticized, as he criticizes others, and that is why he calls for my removal. Silencing your critics will not fill the holes in your arguments.
