Killian Darkwater

Killian Darkwater is the mayor of Junktown around 2161 and the owner of Darkwaters general store.

Background
Killian is the grandson of the founder of the town, an American soldier who found himself without an allegiance after the nuclear holocaust. He is a tough, but fair leader, aiming to make Junktown a safe and prosperous town. He values law and order above all else, putting him at odds with the less reputable elements of Junktown's society, especially Gizmo, who resents Killian impeding his business.

He wears his grandfather's dog tags around his neck, never parting with them.

Interactions with the player character
The Vault Dweller may decide to help Killian obtain incriminating evidence on Gizmo which is used as provocation to eliminate him and transform Junktown into a town where Darkwater enforces his own brand of justice, making life fair and safe under his law. Unless you are considered one of Gizmo's kind, of course.

During the Get Gizmo's confession quest, you are requested to plant a bug on Gizmo or tape an incriminating conversation with him, should you decide to betray Killian by accepting Gizmo's offer, you enter the Kill Killian quest and, once you complete the game, Junktown becomes a large, well maintained tourist attraction ran by Gizmo.

If you side with Killian and get him the confession he will ask for your participation in the Take Revenge on Gizmo quest.

Appearances
Killian appears in Fallout as a Talking Head voiced by Richard Dean Anderson.
