Once you’ve got your group concept sorted make sure you post some info here if you want to recruit - Group Recruitment Thread 2018+
Other suggestions, potentially have some clear roles your recruiting for, i.e you’ll need a Wise One, possibly a priest of some kind and probably a Merchant so mention those when you’re recruiting.
Other things to work out, how your group will run IC, dictatorship, ruling council, loose alliance etc and also your ground rules and social contract OOC. This includes how the effort of setting up and looking after your camp is shared, if you’re a knives in (inter group PvP ok) or knives out (inter group PvP not ok) group and anything else about how to make sure you’re all comfortable with each other. That can include if it’s possible for people in the group to blackball others from joining if they make them uncomfortable. Also when it comes to inter group disagreements who has the final say.
You can work this stuff out as you go, but it’s good to start off with some clear ideas.
I think recruiting with the IC goal of being a senator and their “west wing” is pretty cool, specially when you put a Varushkan twist on that as I don’t think it’s been done before.
