Dead Horse Stalker

Dead Horse stalkers are the stalkers of the Dead Horses tribe, living in Zion Canyon. They can be found in the Dead Horses camp and more particular near Three Marys, where they follow the movements of the White Legs and aid the Courier in attacking them during Crush the White Legs.

Background
They speak using a combination of the Dead Horses language and English (the latter likely being taught to them by the New Canaanites).

Appearances
Dead Horse stalkers appear only in the Fallout: New Vegas add-on Honest Hearts.
