Worker caste

The Worker caste was the largest caste among the Yuuzhan Vong. Despite their size, they were the lowest caste. Workers included Yuuzhan Vong born as workers, those who failed in other castes, the Shamed Ones, and slaves. Some had a little honor, but most were looked on in contempt by the Warriors and the Priests.

Eventually, the Workers, particularly the Shamed Ones, came to believe that the Force was the remains of Yun-Yuuzhan, and that the Jedi were connected with the Yuuzhan Vong. They rose up against Shimrra and the Warriors, and the chaos they caused was vital in the Liberation of Coruscant.
