The Order of Yun-Yuuzhan was the cult of Yun-Yuuzhan, the Creator God of the Yuuzhan Vong. The Order was one of the more powerful sects among the Priest caste, despite the fact that the Supreme Overlord of the Yuuzhan Vong was the final authority in interpreting the will of Yun-Yuuzhan.
In the klekket following the Battle of Coruscant, the Priest Takhaff Uul, along with other members of the Order and Shapers of Domain Dal, organized a conspiracy to control Warmaster Tsavong Lah by sabotaging his radank claw implant. Their initial goal was to have a planet converted into a giant temple for Yun-Yuuzhan. Lah, however, soon realized the conspiracy, and killed several of the priests.
