Tizo'pil Yun'tchilat

The Tizo'pil Yun'tchilat or the The Day of Comprehending the Will of the Gods is the Yuuzhan Vong ceremony where one dhuryam is chosen to be the World Brain. First the thirteen dhuryams' telepathic contact with their slaves by the Shreeyam'tiz, their only job. Then the dhuryams begin to eliminate each other (either by killing each other or by some other method) until only one remains. That dhuryam becomes the World Brain, assuming direct control over Yuuzhan'tar and managing the thousands of biological processes, and the supervising the Vongforming and maintenance of Yuuzhan'tar.
