The clock is ticking. Your team of Investigators have been sent to R’lyeh for the purpose of reinforcing the failing gate, trapping Cthulhu in his prison forever. The Investigators have two enemies. The clock and the cultists hidden among their numbers. Triggering the four needed incantations will take all of the skill your team can muster and you don’t have the luxury of time to search for the traitors in your midst. The odds are slim, but the fate of the world rests in your hands.
