Summary
- Ahsoka retconned the Blade of Talzin to differentiate the Nightsisters from other Force-wielders, giving them their own unique smoky green sword.
- The Blade of Talzin was originally a corrupt lightsaber, using tainted kyber crystals to emit a putrid smoke and give the Nightsisters an upper hand.
- The retcon opens up new possibilities for the future of the blade, including its potential appearance in upcoming Star Wars live-action or animation projects.
The Nightsisters have truly had a chance to shine in the Ahsoka series, but one important piece of their canon Star Wars history has been retconned – and thus erased. Though the Nightsisters have been around for many years, Ahsoka earned them the chance to make their full live-action debut, allowing more about the witches of Dathomir and their culture to be revealed. As a people who have had a large impact on animated Star Wars stories, Ahsoka sets up the Nightsisters to do the very same in live-action, emphasizing their importance going forward in the New Republic Era.
One of the most exciting Nightsister moments in Ahsoka is the return of the Blade of Talzin, formerly of Mother Talzin. Arguably the most influential Nightsister of Star Wars: The Clone Wars, Mother Talzin was the first to wield this blade, summoning the weapon from the nether to battle Jedi Master Mace Windu. In Ahsoka, the Great Mothers give the blade to Morgan Elsbeth, but its live-action depiction is different from its animated counterpart.

First introduced in The Clone Wars season 6, the Blade of Talzin's origin is actually closer to that of a lightsaber than it is a sword. The sourcebook Nexus of Power, released in 2016, reveals that the Nightsisters would use tainted kyber crystals for their green, smoking blades, making their weapons something of a lightsaber themselves. When ignited, the blades would emit a thick, putrid smoke that would choke their opponents and give the Nightsisters their own kind of upper hand. This means that the Blade of Talzin was essentially a corrupt lightsaber, drawing upon the same source of energy as a lightsaber to be used for a more sinister purpose.
