Both the Ixians and the Tleilaxu are integral to the economy of CHOAM and the
Imperium as a whole.
The royal family of Ix had once been one of the wealthiest in the Imperium, in
amongst the elite.
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.
The Tleilaxu
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.
The Ixians
The cyborg, Prince Rhombur of House Vernius, leads the Ixians, masters of
manufacturing and technologies only they know how to deploy.
Not only does the expansion contain new Houses for the Core Game, the expansion also introduces new game mechanics to help players gain advantages
over their rivals.
