Importance of Ix

A technological planet in the Old Empire that plays an important role in earlier Dune novels, Ix is seen in Heretics of Dune as a satellite of the Guild. Ix for millennia skirts the Butlerian Jihad, which iconoclastically bans mechanical computers and succeeds in developing navigational devices that free the Guild from dependence on the spice melange. Ixians in the Scattering are shown developing a new T-probe that is used without success on Bashar Miles Teg to find the location of the ghola he protects. The agony somehow enhances Teg's reflexes and gives him double vision.
