The shapers tasked with collaborating with Nen Yim utilized a damutek of the eighth cortex, a damutek cultivated specifically to populate the eighth cortex of shaping protocols. A platoon of Warriors provided constant security for the damutek, serving both to deter unauthorized entry and to restrict the shapers' movements. Initially, when Supreme Overlord Shimrra first landed on Yuuzhan'tar, the damutek resided far from the Sacred Precinct. Nevertheless, by 29 ABY, its location had shifted to the same complex as Shimrra's Citadel. During the arrival of Jedi Knights Corran Horn and Tahiri Veila, who intended to "abduct" Nen Yim and transport her to Zonama Sekot, an assault occurred at the damutek.
