Vault 119 is an irradiated, abandoned ruin located under the Teton Mountains. Constructed by Vault-Tec before the great war, it was meant to test the interaction between academics and criminals trapped inside. It became a small war zone for generations. Two large tribes, the Painted Sons and the Asherites emerged from the Vault. Finally with the ascension of Lord Protector Denton Van Kyp the Vault was destroyed and the Teton Protectorate was formed.
