From the looks of things there are currently three Brigand groups. Guess what? Make some sort of council, conference, group of all the leaders, or that 'conclave' (which i know nothing about) so you can work as a big team to get things done.
Though from what I saw, that other group wants to actually take your officialdom. So the above option might not work, since they would obviously rather compete then work with. At least, that's what it looks like and if that's the case then you'll need to step up your game, regardless of RL issues or lack of your own player inactivity.
