this confuses me:
Gaul has 3 Legions designated by the senate to keep the peace.
how exactly are we going to implement that ingame? unless you're referring to a provincial legion/personal legion. then I've no problem with that; and shall propose some CA's next session to make that part easier to implement.
something like defining which regions belong to which provinces, etc. like what I've done in my Hayasdan campaign; defined a group of regions as a "province" and a few provinces as a "superprovince" (couldn't think of a better name) and have regional armies patrolling/guarding it.

and about those offices, when the person A is given a region to govern after his term as consul; how long does the governorship last? a session, 9 years, for life, etc?
