The Order of the Silver Twilight features 3 copies each of 55 never-before-seen cards - 40 for Order of the Silver Twilight, 2 for each of the existing factions, and 1 neutral card - that will permanently change the environment of the Call of Cthulhu metagame. Moreover, from this expansion forward the Order of the Silver Twilight will be a full faction within the game and all future expansions of the Call of Cthulhu card game will feature cards from the Order of the Silver Twilight alongside the other factions.
The Order of the Silver Twilight is made up of a secret cabal of leading politicians, charismatic socialites, persuasive civic leaders, and successful businessmen who must pass through successive ranks of occult initiation and ritual to emerge into the inner sanctum of the Order, there to pursue their quest for ultimate earthly - and unearthly - power. To represent the Order's magical mastery in the game, The Order of the Silver Twilight introduces an assortment of versatile and challenging cards whose game mechanics mesh well with a variety of decks and play styles.
