The Chieftain's skull was eerie, and humanoid in appearance.

The Chieftain's skull was one of three important relics kept by the Tusken Raiders in their relic cave. The skull was what remained of a fallen Tusken chieftain. Kept as a shrine in the cave, the skull was placed on a throw pillow, and surrounded by an aura of green colored flames. The skull was eerie and humanoid in appearance.

The skull and two other relics were stolen by a spacer sometime after the Battle of Yavin in 0 BBY. They were delivered to scholar Srimaur in the city of Mos Espa for study, but the theft enraged the Tuskens. In retribution, the Tusken King led an army of Sand People to invade Mos Espa.
