Villip Beacon
this was a form of villip, bioengineered by the Yuuzhan Vong to send a signal back to a companion villip or villip choir. What made the villip beacon different from a standard villip was that it was easily concealed, and did not form itself into the guise of its companion's user. Rather, it simply recorded what it observed and transmitted it to its companion. Villip beacons were often used for covert surveillance, with an agent carrying one hidden in their robes in order to transmit images and sounds from an enemy location.
