The Udam tribe, also known as Flesh Eaters, is an antagonistic tribe led by Ull that resides in the Northern Arctic Tundra in Far Cry Primal. The Udam are viewed as barbaric and primitive cannibals who had migrated from Northern Europe into Oros. They appear to be in conflict with the Wenja and the Izila tribes for resources and territory. They are loosely based on the Neanderthals, and worship a relic called the Stone Woman as their deity. They are slowly becoming extinct due to the tribe's mass-affliction with "skull fire" a byproduct of their cultural habit of consuming fallen humans for religious purposes and out of desperation, as well as through generations of inbreeding.
