Ghost People

The  are a faction in the Fallout: New Vegas DLC Dead Money. They inhabit the area surrounding the Sierra Madre.

Background
Protected by Hazmat suits, yet morphed into something no longer quite human, the Ghost People are the only ones to walk the Cloud. Anyone who isn't savagely killed when they first hear the insidious screaming the Ghost People make is dragged away to a fate that, while as of yet remains entirely uncertain, is probably much worse than dying in the streets.

They are very mysterious, they don't talk to their victims, they're evidently quite agile, highly territorial, they have glowing green eyes, and reasoning skills equivalent to that of the average Feral Ghoul. They don't die very easily - to really kill them you have to decapitate, dismember them or feed them to a certain nightkin.

Interactions with the player character
All Ghost People are hostile to the PC. To kill them you must remember the three D's: decapitate, dismember, or disintegrate, if you can. If Dog is your companion he will eat them when they are knocked unconscious. They usually carry Knife Spear and Bear trap fist

Appearances
