Not all Imperial factions are aligned or alied. There are those who want to safeguard their sectors and build up their own power to make a bid for the throne, others who'll go rogue and cut off their own slice off the Galaxy to rule. Think of the diadoch generals after Alexander the Great's death, or the warlordism of the late Roman Republic.

Very true, and had considered such a faction. Actually also got another possible idea. A Moff being a Follower of the Pius Dea, who were thought long dead for many millennia. 

Which do you guys think would be better? An Renegade Imperial Warlord, a Resurgent Pius Dea?(Kinda the same as last, but with a religious twist and other things), Or a Local Warlord in the Outer Rim.
