Drawn into an online Cthulhu campaign by curiosity, Liu Xing discovers the game is far more real than anticipated. As an investigator navigating a realm where knowledge breeds death, he must confront eldritch horrors and unknowable entities that blur the line between tabletop fantasy and horrifying truth. In this TRPG-inspired xuanhuan world, every choice spawns unexpected consequences, and survival depends on embracing ignorance. When the dice roll in darkness, the game's rules become the only shield against cosmic dread and the incomprehensible terrors that hunt those who know too much.
