I'm planning on using established guilds as npc rivals. The player characters start out as nobodies, in some cases as slaves, and will eventually have the opportunity of starting up their own guild(once they earn enough gold). It occurs to me that a guild charter would prove useful, preferably several different ones. Problem is I don't know how I would be able to write one!
So does anyone have any examples, or alternatively solid guidelines on what should go into an adventuring guild charter?
