GM Resources

Everything printable and downloadable for the Game Master, in one place.

The GM Guide, the ten-tool booklet, the Shadows of the Compañeros campaign with handouts, and the player-facing documents you can hand out at the table. Everything marked Restricted contains campaign spoilers, keep those on your side of the screen.

Edition note: some older PDFs, including the GM Guide, refer to the former “Player’s Handbook,” now titled the Setting Guide. They remain usable as they are. Download the current Setting Guide.
