In the Gloom card game, you make your eccentric family of misfits suffer the greatest tragedies possible before helping them pass on to the well-deserved respite of death. Just mix the 55 transparent cards included in this set together with your copy of Gloom to add morbid new Modifiers, Events, and Untimely Deaths, and a new family -- the artistes of Le Canard Noir, whose creative endeavors always end in disaster.

Also included are five Residences with a light blue background behind their central illustration. These are each placed next to their related family at the start of the game. New cards called Mysteries, which have a dark blue effects bar at the bottom, are also shuffled into the deck before play. A Mystery is the only card that can be placed on a Residence (and only a Residence), and can be placed on any Residence as either of your two plays. It gives that Residence's player a special effect and Pathos points that count toward his final Family Value. A Mystery remains even if the requirements for playing it are lost. You may discard a Mystery from your hand as a free play.
