Yeah I had very creative ideas for the Hall of Brothers when I brainstormed while I was doing some work, sadly I forgot a bunch of the ideas before I got to typing them down but I’ll update the main post again as soon I have time to flesh it out better!
This comes from an earlier vision I had where you could actually build a fortress in the map, like the guard tower etc (and the brothers you kept there could get sieged so you had would have X ingame days to go there and help out so your fortress wont get sacked). However a Hall inside a city would not require much extra work or coding, while still providing extra content imo
