The Yellow King RPG Black Star Magic

Ritual magic of the Belle Époque! The desperate Science Jaune of a war-torn continent! Parageometrical horrors perfected in the labs of the tyrannical, overthrown Castaigne regime! Signing, the latest way to turn social media dysfunction into sorcerous reality! Your players can master them all—at perilous risk! Each spell is a Shock card with effects both useful and sinister. Do they hold onto that that spell they need to do that thing, even as their inner realities start to break apart? Or do they take the safe route, and cast out the buzzing, insistent power of the Yellow Sign?
