This expansion adds two new houses, the Ixians and the Tleilaxu, to the Dune boardgame. Both the Ixians and the Tleilaxu are integral to the economy of CHOAM and the Imperium. The royal family of Ix had once been one of the wealthiest in the Imperium. Because of a successful invasion of Ix by the Tleilaxu and the Emperor’s Sardaukar, and then, after many years, the liberation of Ix by Ixian and Atreides forces, the Ixians and the Tleilaxu are mortal enemies.
