Iron GM Games


Sean Astin Explains Grimmerspace from Grimmerspace on Vimeo.


Looking to turn up the dial on the science and horror in your science-fantasy Starfinder game? Look to Grimmerspace, if you dare. In a science-only horror galaxy invaded by magic, immortal mages bent on conquest tear through space-time from the other side of the universe only to collide with the Grimmers, gritty defenders, locked and loaded against any threat. It’s bullets versus fireballs when science and magic come to world-ending blows!
