Hu...so when someone who's name I'm not going to mention here starts shooting, mh... let's call them "Z", for mh...let's say "less reasons", it's ok, but when those "Z" call for help then and someone, who's thread this is, responds to the help request, since they aren't so far aways from the "Z" like you would think...it's not ok?
The IMG and the CR are one system aways from FP 10. Seeing the Zoners threatened by the BHG (Core) is something that affects almost all of Sirius Independent -, Border- and Edgeworlds. Why shouldn't the CR not think what the BHG (Core) is doing is bad?
And as said before, they already had expeditions out there.
(IMG is no military force besides their Defense Wing. Involvement in another war while their operations are threatened is not a good choice. I think "we" chose to stay out of this for good reasons.)
I don't see that much reason, why they shouldn't get involved too. It isn't like it's just some small war between two houses, it's a bit bigger than that, considering how many factions are involved. And everyone wants a piece of the cake it seems.
