While I deeply appreciate the design goals and ideas in Artists, Artisans and Workers, it could have been better edited both as far as format and, more important, in mechanics. However, if you want to highlight character backgrounds and draw more upon medieval European history for your campaign setting, there is good food for thought here.
Artists, Artisans and Workers: Bold Background Series I is a 49-page PDF (45-pages if you remove the covers and OGL page) for the Pathfinder RPG written by Jarrod Camiré and published by Taurus Twelve. This product is the first of Taurus Twelve’s Bold Background series.
