Battle of Dathomir

"The time has come at last to take revenge on Asajj Ventress and the witch Mother Talzin. I have learned Ventress has returned to Dathomir. Go there, and wipe the witches out. All of them."

- Count Dooku, to General Grievous

During the Clone Wars, the Confederacy of Independent Systems launched an invasion of the planet Dathomir that resulted in the annihilation of the Nightsisters; all of the Dathomir witches were killed, save for Mother Talzin and Asajj Ventress. The assault was led by General Grievous on the orders of Count Dooku.
