Dooku's voodoo doll

Dooku's voodoo doll was a Nightsister doll created by Mother (title) Talzin with the help of Allyan magic during the Battle of Dathomir in the Clone Wars, circa 21 BBY. It was created to torture Count Dooku, so that he would call his Separatist forces led by General Grievous back, otherwise to kill the Count. However, Grievous killed Old Daka, killing the Army of the Dead, defeating all the Nightsisters.
