Shapers
this caste of Yuuzhan Vong society was known for their ability to create living technologies from raw, organic materials. There were three tiers of Shapers: Initiates, Adepts, and Masters. Like most other Yuuzhan Vong castes, the Shapers had a patron diety, known as Yun'N'Shel. As an Adept grew in power and skill, they ritually scarred themselves in ways similar to that of Yuuzhan Vong warriors. However, the mutilations of the Shapers were purely functional. Chief among them was the removal of each natural hand, which were replaced with specially-grown hands equipped with various tools and blades for use in shaping new forms of bio-technology. The right hand was the most obviously different, having a cephalopod shape and eight fingers instead of five. Another distinguishing feature of a Shaper was the unusual headdress they wore, which seemed to writhe like a Medusa's head and was attuned to the Shaper's emotional state. Once the Yuuzhan Vong realized that the Jedi Knights were unusual enough to manipulate the Force - an entity that didn't exist in their galaxy but obviously could be used - several sects of Shapers were put to work on finding a way to exterminate the "Jedi problem."
