I was thinking it would be nice to be able to build a town hall where you can officially record civilians in your town/city and set ranks/roles but also have a table inkwell and caged ravens that could be used to send messages to towns people based on rank or even to other towns and the message could go to a phone app if someone is afk. Also the ravens would have to be tamed bred and fed making sending ravens something that can't be spammed but thought about.
Examples: Town is under attack send ravens to soldiers and knights, proposing alliances or trade to other towns, delivering demands etc.
I think this could add a fun mechanic and a call for a Maester style role to towns though I know an app could take time. Any thoughts guys?
