Xavier, Manion Butler Jr. This incites the rebellion of human slaves and eventually the Jihad against the machines. Serena, as Priestess of the Jihad, becomes one of the religious leaders of the human rebellion. Upon her father's retirement, she became interim Viceroy, but was later relegated to a figurehead by Patriarch Iblis Ginjo. She eventually travels to Corrin, ostensibly to negotiate a peace but actually to provoke Omnius into martyring her and thus motivating war-weary humans to fight the Jihad until a victorious end. In 108 B.G., Serena posthumously becomes the focal point of the fanatically anti-technological Cult of Serena, founded by her great-grandniece, Rayna. Xavier Harkonnen (223-154 B.G.) is a young military officer leading the defense against the cymek attack against Salusa Secundus. Xavier courts Serena Butler and fathers her son, Manion, but after she is abducted (and presumed dead), he marries Serena's sister Octa. Through this union, Xavier becomes the ancestor of both House Corrino and House Harkonnen. In the Jihad, he serves as a Primero (general) alongside Vorian Atreides, who turns from a rival for Serena Butler's love into a good friend. Upon Xavier's suggestion, Omnius's primary stronghold on Earth is destroyed with a massive nuclear strike. Later on, finding out about Iblis Ginjo's organ raids, Xavier takes control of Ginjo's spacecraft and flies it directly into the Tlulaxa sun Thalim, carrying Iblis Ginjo to his death. In the process, Xavier not only sacrifices his life but also his reputation as the public, ignorant of Ginjo's corruption, regards the latter as a martyr while Xavier is marked as a traitor. Most of Xavier's descendants afterwards shun the name of Harkonnen in favour of Butler.
