Fallout: Mile High
The Church of Jesus Christ of Latter-day Saints, more commonly known as the Mormon church to most who are not members of the church, is the largest denomination originating from the Latter Day Saint movement founded by Joseph Smith in Upstate New York in 1830.
Adherents, often referred to as New Canaanites, view good works and adherence to the teachings of Jesus Christ as revealed through Joseph Smith as the central tenets of their religion. Groups of Mormons still survive in the wasteland, mostly in the area that used to be known as the state of Utah. In 2281, the head of the church resides in New Canaan, built upon the ashes of Ogdon, UT.
Though truly brutal groups like Caesar’s Legion will not hesitate to enslave or kill Mormons, most tribals and other organizations leave the Mormons alone, knowing that they often will voluntarily give medical or other aid to groups who need it. The people tolerate the Mormons’ preaching because finding help with relatively benign conditions is rare.
