This expansion introduces two new factions, the CHOAM and the Richese, to the Dune boardgame, along with 2 new variants.

The Combine Honnete Ober Advancer Mercantiles or CHOAM has controlled much of the economic affairs across the cosmos, and had a keen interest in Arrakis above and beyond spice production. Because of its dominance of inter-planetary commerce, CHOAM was the largest single source of wealth in the Imperium. Influence in CHOAM has been a major focus of political maneuvering in the Imperium, both to maximize dividends and also to skim profits. The bureaucrats and leaders of CHOAM were dedicated to controlling vital products that enriched the Great Houses . . . and CHOAM itself.

House Richese, just like the Ixians, had a well-earned reputation for ingenuity, and made important technological inventions. But Count Ilban Richese has suffered a number of business blunders that threatened to bankrupt their fortunes. After being ousted from governing Arrakis, they were reduced to selling off important creations simply to gather enough funds to continue their efforts to compete.

This expansion also adds Leader Skills, which let you assign a skill like Mentat, Swordmaster of Ginaz, or Prana Bindu Adept to one of your leader discs. It also comes with Advanced Stronghold Cards, which give you a "homefield advantage" when battling in a stronghold you control.
