In episode 12 of “The Long Way Home” (our military based Twilight 2000 v4 campaign set in Poland and telling the story of some survivors of the US 4-12 Cavalry) the PCs resolved a dispute with some locals without resorting to violence and then found out more about the fabled Free City of Krakow, in particular what it takes to obtain a citizenship token and become an official Citizen with rights to enter the central walled city.
