Lore & Background

Wallach IX is the homeworld of the Sisterhood, the order that will eventually become the Bene Gesserit. The planet houses the Sisterhood School, where young acolytes like Lila are raised with no knowledge of their biological families, so as to emphasize the importance of the Sisterhood in their lives. The school is where the dangerous Agony ritual is performed, as seen when Lila is administered the deadly Rossak poison to unlock her Other Memory and access the consciousness of Raquella Berto-Anirul, the founder of the Sisterhood. The planet is also where Tula Harkonnen keeps a secret thinking machine-powered life-support machine, named Anirul, to repair Lila's damaged brain after the ritual fails. The Sisterhood's plans for humanity are directed from Wallach IX, and it is from here that Mother Superior Valya Harkonnen faces threats to those plans.
