The Mythras GM Screen contains 16, 11x 8.5" cards featuring artwork and essential tables from the Mythras core rules. Seven of the cards feature cover artwork from Mythras titles and are player-facing, while the remainder contain a variety of tables and charts.
Permission is given to print the contents on quality card stock so that you can assemble your own screen, or use the inserts with Hammerdog Games' World's Greatest Screen, which can be bought separately from http://hammerdog.com/twgs/ (you need the landscape version to use with the inserts). Don't need the Theism charts this session, but you do need travel tables? Simply insert the Travel & Environment card along with three others that will be needed for play into the GM side of the screen. The set even includes a duplicate, player-facing copy of the Special Effects list.
