We've had a couple run-ins with BMM, been a little grump going back and forth, and I know they've issued a KOS order amongst their employees. In return, there is a bounty on BMM ships operating in the Taus and Orkney. As for all of the rest of Bretonia, however, I don't think it's quite to the point where lawfuls can exactly hunt us. I did get blasted away by an OG a few weeks back, but I'm still not exactly sure why. I probably smelled too strongly of cheese.
When we go into Bretonia, we expect to be treated with disdain. I imagine an order for us to leave would be within bounds, and refusal beyond that could be considered grounds for an attack.
Really, with my guys, as long as you're roleplaying, I'm not exactly concerned about the outcome. Being Gallic, we expect to not be superfriends everywhere. As long as there's some sort of logical run-up to whatever action you take, I'm cool with it, and I'll make sure my guys roleplay back in kind.
