Provoker Spineray
this Yuuzhan Vong creature was bio-engineered for use in stimulating the nervous system of another alien creature. These creatures were developed specially for the species on which they would be used, and could be manipulated to cause pain to selective nerve arrays. With the use of a provoker spineray, a Yuuzhan Vong Shaper could map out a being's nervous system and what each set of nerves was designed to do. The use of a provoker spineray was controlled by the Protocol of Tsong, and required that the Shaper use an ol-villip to monitor its actions.
