A planet situated in the Laoujin system, Wallach IX was a Synchronized World during the ancient times. When Yorek Thurr abandoned the League of Nobles, he was appointed its ruler.
In the next millennia, it served as the main planet for the Bene Gesserit Sisterhood. Their main school was located there as were extensive training facilities. The planet was surrounded by a defensive shield which was impenetrable. Almost all sisters underwent training at this planet when situation allowed.
A Mentat Duncan Idaho ghola visited Wallach IX during the time of God Emperor Leto Atreides II's reign to suppress a Mentat school the Sisterhood had thought they had hidden there.
