Killian Darkwater

Killian Darkwater was the mayor of Junktown around 2161 and the owner of a general store. There was a power struggle between Killian and Gizmo, the owner of the local casino. Eventually, Killian managed to get rid of Gizmo with the help of one known as the Vault Dweller, and transformed Junktown into more of a lawful town, which eventually joined the New California Republic.
