The Ancestral Mask is an ancient Yautja bio-helmet used by the ancient Yautja, Lord, and later by Dark. It is regarded by other Yautja as a symbol of high authority in their culture.[citation needed] It has the Alien Vision mode, which enables the wearer to locate Xenomorphs and their hiding places with great ease. Also, like the modern Bio-helmets, it has a built in system to record previous events (like Lord's victory of over the Xenomorphs, and him bringing the Matriarch to the temple), but unlike the modern ones, the Ancestral Mask also appears to record whatever its wearer is doing from a third person perspective. After being briefly connected to Lord's sarcophagus, it downloaded data that contained the coordinates of Xenomorph Prime
