As he delves deeper, he discovers the symbol is a gateway to a hidden world of nightmares, where the victims were lured and tormented before their deaths. The symbol, he learns, is a beacon for a malevolent entity that feeds on the suffering of its victims, using their nightmares to fuel its power. James must face his own deepest fears and confront the entity before it consumes the city and plunges it into a realm of perpetual nightmares.
