Spacing Guild
In the series finale, "Sandworms of Dune" (2007), it is revealed that the autonomous Face Dancers are creations of the reincarnated Omnius and Erasmus but seek to overthrow their machine "masters" as well. Secretly in control of Ix and its technology production, Khrone manipulates the Spacing Guild and New Sisterhood, setting them up for disastrous failure in their final battle against the thinking machine forces of Omnius. When Khrone asserts dominance over even the machine empire, a smug Erasmus activates a fail-safe built into all enhanced Face Dancers, instantly killing Khrone and all of his minions across the universe.
