Nightsister crystal ball

The Nightsister Crystal Ball was a device created and used by the leader of the Nightsisters of Dathomir during the Clone Wars, Mother Talzin. Talzin was able to craft the crystal ball due to the Nightsisters' unique connection to the Force. The crystal ball allowed Talzin to see visions of the future, or to determine the location of individuals such as the Nightbrothers Savage Opress and Darth Maul.
