I like you’re stronghold suggestion and was thinking about it. Mercenaries tend to be very roam-heavy. So if not a stronghold I could see some kind of upgrade-able baggage train/ camp.
Due to the decent amount of flavour text on stuff like the flagellant and the monk I can see religion getting more added to it (maybe a cthuluesque old god enemy faction?)
I’m not really a fan of the Alchemist because it seems kind too fantasy for the girtty theme of the battle brothers, I could potentially see another faction using it though!
