Hmmm. How about the councils made connections with gains and move through forre or what to the remote area of gallia and capture some unguarded region. It is not insane thought as most of the gallic fleet is in tau then the gallic remote world must be unguarded. And if councils capturs those then gallic fleet has to pull back.
I just dont like the idea of washing bretornia from map.
I also like the idea of corsair invasion. If they control planet chembreidge and chembridge research staion it will be very nice addition for 4.87.
However its sound crazy when we dont have 4.86 and talking about 4.87. But its my imagination.
