Satan Xerxes Carnacki LaVey (sometimes known simply as Xerxes LaVey ^[1]) is a LaVeyan Satanist and the son of Anton LaVey. He was born on November 1, 1993 to Anton and Blanche Barton. ^[2] On October 29, 1997 Anton LaVey died of heart failure. On November 7, 1997 Karla LaVey, Xerxes' sister, held a press conference to announce the death of Anton LaVey. It was at this time that Blanche Barton and Karla LaVey announced that they would run the Church of Satan as co-High Priestesses. Several days later, Barton produced a hand-written will claiming that LaVey had left all of his belongings, property, writings, and royalties, including the Church of Satan, for their son, to be put in a trust managed by Barton. Karla contested this will, which was later found to be invalid. ^[4]

A settlement was reached in which Anton LaVey’s belongings, writings, and royalties would be split among his three children, Karla, Zeena and Satan, and that Barton would receive the “corporation known as Church of Satan.” ^[4]
