House of Cards
The fate of a city lies within a dungeon whose doors are sealed with - cards
It's up to you to bring it tumbling down.
“House of Cards” combined dungeon exploration with the Deck of Many Things to create an adventure experience unlike anything seen before. The deck is both a treasure and a trap, guarding a tomb complex that’s being used by the Night Masks thieves’ guild as a lair. If the PCs want the deck for themselves, they must first gather all the cards, which is easier said than done. - Christopher Perkins
