User summary: Cabell Manor presents a rules-light haunted house adventure. No game master is used; the players take turns creating a shared narrative experience. Play proceeds in turns. During each turn a player rolls the dice and narrates a segment of the adventure depending on the roll. Players also draw cards (from a custom deck) and respond to the events on the cards. The composition of the deck changes during game phases. Note the card deck itself is provided as a print-and-play component of the game (and makes up the bulk of the document).
