The Tleilaxu, led by Hidar Fen Ajidica, took advantage of the suboids desire to not violate the prime commandment of the Orange Catholic Bible against producing Thinking Machines. For months prior to the Tleilaxu invasion of Ix, designed by Elrood Corrino IX who wanted revenge against Dominic Vernius, the Tleilax secretly stirred up rebellion amongst the suboids. This peaked with the full-scale invasion of Ix by the Tleilax, who were helped by the Emperor's Sardaukar troops.
