The *Sanctum of Twilight* expansion brings a fresh chapter of terror and intrigue to the already chaotic universe of *Mansions of Madness: Second Edition*. Two newly recruited investigators arrive at the mansion to uncover that the noble Silver Twilight Order is plotting a ritual that could open a portal to the unknown. In two scenarios – *The Silver Twilight Lodge* and *The Sanctum of Twilight* – players must unravel secrets, battle monsters, and stop the evil from spreading. The expansion adds 20 new event cards, 10 action cards, a new monster (the *Silver Twilight Cultist*), and 5 new object cards, plus area‑movement mechanics that demand attention to character positioning. Investigators gain new abilities, and the digital app remains the backbone, logging clues, tracking health, and managing monster AI. The experience stays cooperative, but with tougher challenges and higher tension, thanks to improved hand management and variable player powers. If you love mystery, cosmic horror, and team strategy, *Sanctum of Twilight* will take your game to another level of fear and fun.
