Ahsoka's Big Villain Twist Makes No Sense

Dathomir has a long and storied history in the "Star Wars" universe. The mystical planet was first introduced in the 1994 Expanded Universe novel "The Courtship of Princess Leia," along with the primary denizens of Dathomir, the Nightsisters. At the time, these magical beings were referred to only as "Force witches." When Dathomir was given a more central role in "Star Wars: The Clone Wars," the new moniker took over.

Even with the name change, though, the Nightsisters remained quite witchy. "The Clone Wars" details how Asajj Ventress, Count Dooku's Sith assassin, left her Nightsister commune on Dathomir and its powerful leader Mother Talzin to serve the Separatists. After being scorned by her new master, Ventress returns to Dathomir and hatches a plot of vengeance. The animated series also changes Darth Maul's backstory to make him a son of Dathomir. By the end of the show, Talzin has made herself a thorn in the sides of both the Republic and the Separatists, earning the attention of Darth Sidious himself.

Through a series of conflicts in "The Clone Wars" and the "Darth Maul: Son of Dathomir" comics, Talzin and the Nightsisters are effectively wiped from existence. Palpatine sees them as an immense threat due to their powerful and unique dark Force magic, so he removes them from the galactic board, so to speak. But then, how did a survivor of this brutal purge find her way into the welcoming arms of the Empire?
