Summary
The Acolyte's showrunner Leslye Headland has confirmed one major fan theory regarding the show's true Sith master isn't accurate. Mother Koril is a Zabrak, a race that has been key in Star Wars already, specifically in the prequel trilogy era. The Zabraks have ties to the Nightsisters of Dathomir.
The final episode of The Acolyte premieres on Tuesday, July 16th, at 9 PM EST/6 PM PST on Disney+. Mother Koril's fate will depend on whether the show is picked up for a second season, which hasn't been confirmed.
