Theilaxu: Led by a small council of Tleilaxu Masters - the fanatic, xenophobic Tleilaxu were tolerated because of their useful genetic engineering superiority. Although underestimated and loathed by others, they hoped to someday dominate all.
Ixian: The cyborg, Prince Rhombur of House Vernius, leads the Ixians, Master of Manufacturing and technologies only they know how to deploy.
This expansion adds two new houses, the Ixians and the Tleilaxu, to the Dune boardgame. As well as introducing new game mechanics to help you gain advantages over your rivals.
This base game of Dune is required to play this game.
