Eighth cortex

The Eigth cortex was supposedly the final level of shaping protocols available to the Yuuzhan Vong. Only the Supreme Overlord knew what was in the eigth cortex, and saw fit as to when he should distribute the information to the Shaper caste.

In reality, by the time of the Yuuzhan Vong Invasion of 25 ABY, the eigth cortex was still empty. There were no new protocols explaining how to defeat the tenacious, versatile infidels who populated the galaxy. The shaper Onimi saw this, and sought to fill the eigth cortex, manipulating his puppet Shimrra into allowing the heretic Nen Yim to design new protocols herself. The Eighth Cortex Damutek was located on Yuuzhan'tar.

The discovery that the eigth cortex was empty led the Executor Nom Anor into becoming the prophet Yu'shaa.
