What's the win condition? Last post from this series I saw was about the spreading mold. Is the past events still relevant or does the chess board not matter anymore?
Move: any available chess pieces on the board realize the world outside of the board jump outside to capture the trapdoor, capture the table, and/or the zoomed out camera, cancelling out the meta narrative outside the board.
A demon lurks below with a gift. A small piece of cake on a plate that he rests on the edge of the table before he receeds to the darkness to creep on you while you eat it.
