Slave Seed
this was the name of the yorik coral implant used by the Yuuzhan Vong to control those beings they took as slaves. The slave seed began as a tiny grain that was placed inside the slave's body. Most often, the slave seed was placed near the heart, but it could be inserted anywhere on the slave's body. As the slave seed grew, two things happened. First, it established a connection with the nearest controlling organism, usually a yammosk. Then, it extended its own nervous system along the nervous system of its host, developing a deep-rooted connection to the slave. This connection, known as the slave seed-web, was then tapped by the controlling organism, allowing the Yuuzhan Vong to control vast numbers of slaves with a single organism. Like many other pieces of Yuuzhan Vong bio-technology, the primary stimulus for controlling slaves was pain. The controlling organism could direct the slave seed to stimulate or shut down certain nerve clusters, causing a wide range of painful shocks to its host. In this way, slaves were conditioned to do what the Yuuzhan Vong wanted them to do. Slave seeds were engineered with a unique fail-safe: whenever contact was broken with the controlling organism, the slave seed-web administered an intense pain which could only be assuaged by contact with its parent coraltree basal. This was useful during the tizo'pil Yun'tchilat, when the maturing dhuryams had to survive on their own, without the assistance of their slaves. Slave seeds were no longer independent creatures after they began extending their nerves along those of the host. If a slave seed were to be removed from its host, it would die immediately.
