New Jerusalem

Vault 70 was a Vault-Tec Vault located in Salt Lake City, Utah. In 2062, many Mormon congregations came together to purchase places in it.

Most of Salt Lake City and Ogden, Utah were destroyed in the Great War in 2077. Vault 70 opened in 2190 and its residents use their three G.E.C.K.s to found the city of New Jerusalem in the ruins of Salt Lake City.

New Jerusalem's intolerant prophet and apostles repeatedly voted to have no commerce with outsiders from other, failed communities, refugees, or tribals. In 2233, a number of angry tribals, raiders, and disassociated attackers gang up on New Jerusalem and sack it, killing most of the Mormons in the process.

The new living prophet, Judah Black, led most of the remnants of the Mormon community north to Ogden, Utah. They establish the town of New Canaan.
