Yes there is some scope in the fluff but it's implied that the imperium is uniform and monolithic.Major Tom said:No problem. That is a really good idea, and I think there enough scope in the fluff to allow for that. As I understand it the Imperium does allow a bit of free hand when it comes down to the nuts and bolts of actually governing a sub sector or a system, as long as they pay their tithe and worship the Emperor, so it would be natural that different place adopt different ways of doing things that clash with others when they trade or have to fight together.....ACman said:Sorry I've been discussing this with multiple people.
Previously I guess I've been arguing for some granularity in imperial influence. Defined regions/factions where Ecclesiarchy wanes and Administratum dominates or vice versa... Or where some third party rises over them that isn't chaos/xenos/tau/c'tan/spagetti monster of doom.
And pirates and smugglers and bounty hunters, oh my!
But I do have a possible third faction for you: The Adeptus Mechanicus. A forge world or a sub sector dominated by a forge world would put priority on information/orders coming form Mars than Terra, and they often pursue their own agenda alongside that of the Administratum and the Ecclesiarchy, at times at odds with the other organisations. The Emperor is nominally named as the earthly representaion of the Omnissiah, but for all intents and purposes the Tech Priests of Mars have a religion of their own.
I know the fluff is written from the point of view of imperium propaganda/reports to the inquisistion., but there could be more of:
"the tetrach quadrant has fallen under the influence of the Duke Felemar. While he is of no immediate threat to the imperium his power is great enough that detente rather than escalation is prefered in these circumstances"
Let's face it if some lame-ass anime race like the tau can seize an area of space then there should be a human prince that can pull off the same trick.
