Worlds, ridding the universe of Omnius altogether. However, this plan called for the use of the still unreliable space-folding technology in order to carry out the attacks before the machines have a chance to recall the fleet en route to Salusa. The Great Purge is successful in destroying Omnius on all but one planet, albeit with an appalling cost in human lives because each planet was turned into slag, and while all the machines were obliterated, all the captured humans and slaves on these planets were also killed. Each time the human armies fold space to a new location there is a 10% attrition rate due to the undependable space-folders because of the uncertainty principle. In all, it amounted to billions of lives lost. The humans are also unable to destroy Omnius on the primary synchronized world, Corrin. While the other Evermind incarnations are being attacked, the cogitor Vidad travels to Corrin and warns Corrin-Omnius of the human counter-offensive. The machine fleet is recalled to defend their last remaining stronghold. Despite this, Serena Butler’s Jihad is declared over. The Great Purge ended with an impasse between humans and thinking machines on the planet Corrin. While unable to destroy the machines, the human army is able to trap them on Corrin by surrounding the planet with a net of scrambler satellites, so that any thinking machine attempting to leave would have its gelcircuitry mind destroyed. This situation continues for almost 20 years with the machines unable to escape, and most humans unwilling to enter another battle. Omnius, again at the suggestion of Thurr, sends machines with primitive minds that can evade the scrambler network to attack Salusa Secundus and Rossak. These attacks have a limited effect, but are enough to remind the humans that the machines are still a threat. Touting his victory over the Titans (see below), Vorian Atreides convinces the League to attack Corrin. Facing robots using human shields and unable to use their main tactical weapons due to treachery by Abulurd Harkkonen, the Army of Humanity is bogged down around Corrin. They are forced to use most of their atomics to destroy the robot defenders. There is a ground offensive by Ginaz mercenaries that finally destroys Omnius, but not before he sends out an unknown radio message into space. Following the Battle of Corrin, Viceroy Faykan Butler renames himself Faykan Corrino in commemoration. The Cult of Serena Having
