House Wallach was a House Major mentioned in the documents found in the Rakis Hoard. The name suggests that the House's origin was in the Wallach Group of the Kuentsing System (Laoujin) or that it was possibly related to the line of Wallach I. It's exact relation to the Bene Gesserit, whose Chapterhouse was on Wallach IX is unknown, though it could be possible that House Wallach was a political marionette of the Sisterhood.
