Well, not actually in the Arachnid Quarantine Zone, but no one told the Bugs that
Port Joseph Smith is the capital and largest city of the Deseret system. It was founded in 2165 by Mormon Fundamentalists who wanted to start a colony world where they could practice their polygamy and theocracy in peace. Devastated in a Bug invasion in 2194, many of the original colonists were killed. Subsequent waves of settlement by non-Mormons have led to the ending of outright Theocracy, but polygamy remains legal and widely practiced among the 10 percent mormon minority.
