The setting in which Green Banner plays, places them as the knights of Green Banner, part of the army of Vanor duchy, highly organized, well trained and richly funded army of invaders, trying to claim as much land as possible for their duke.
The Duke is a purely fictional character, only mentioned and never played in the game. He sits in his fictional castle, somewhere deep in the Vanor duchy and leaves the command over his troops to the General. As a first playable character, General leads the troops and negotiates with other groups if needed. Next in the chain of command comes the Captain, leading the knights, and Sergeant, leading regular army troops. In every event, Green Banner follows this chain of command and everyone knows their place, which allows better organization and higher functionality of the group.
Sometimes, for the sake of fun and games, someone gets to play a disobedient solder and gets “punishment” if caught. And nobody is mad because of it after the event. It is all a game and it is important is to everyone to have a good time and a great story to tell.
Green Banner is often invited to participate in fairs, festivals, art projects, movies and commercials. They rarely decline such offers. The discipline, experience and equipment they posses, brought the group many opportunities to present themselves to the public, have a good time and make enough money to keep financing Green Banner’s existence. Still, all those armors, equipment and organized traveling require a lot of funds.
