 Players also have a House Deck containing non-unique cards that represent their Aides, Personnel, Equipment, Plans and Tactics (random Event cards may also be included in the House Deck).The Judge of the Change expansion introduced three new Factions (the Spice Miner's Guild, the Water Seller's Union, and the Dune Smugglers), and the Thunder at Twilight expansion contained modified House Atreides, House Corrino and House Harkonnen starter sets (reflecting the period in the Dune novel when House Atreides took possession of Arrakis from the Harkonnen).Each player begins the game with a homeworld and small amount of solaris.
