Dune: Choam and Richese Expansion

This expansion adds two new houses, CHOAM and the Richese. Just like the Ixiams, Richese had a well-earned reputation for ingenuity and created important tech innovations. After being ousted from governing Arrakis, they are reduced to selling off important creations simply raise enough funds to continue their efforts to compete. The Combine Honnete Ober Adavancer Mercantiles, control much of the economic affairs across the cosmos and have a keen interest in Arrakis above and beyond spice production. Because of its control of inter-planetary commerce, CHOAM is the largest single source of wealth in the Imperium. This expansion also introduces advanced stronghold and leader skill mechanics to help you gain advantages over your rivals.
