A Pillars of the Earth game mat for holding all the common materials used by all the players like metal, the extra black worker and various card stacks. This gives the game players a designated spot for all those "other" resources. Two identical pages of the mat are given to allow printing on the front and back of the mat. I never liked leaving the back side of a mat blank. Laminate the double-sided aid after printing. It is recommended using this mat in conjunction with the almighty Holier-Than-Thou player mats made by Major Sholto.
