Yun-Yammka
this deity was the Yuuzhan Vong god of war and carnage. Known as The Slayer, Yun-Yammka resembled a large brain with a single eye and a puckered mouth. An array of tentacles emerged from around its body. Every Yuuzhan Ving warrior kept a statue of Yun-Yammka among his possessions, and prayed to Yun-Yammka for strength in battle. After the Second Battle of Coruscant, the Yuuzhan Vong planned to retake Borleias and turn the entire planet into a shrine for the priests of Yun-Yammka, as much to appease the priests as to discredit Domain Kraal. Yun-Yammka was often associated with the Trickster goddess, Yun-Harla. Because of this, many Yuuzhan Vong began to assocate Yun-Yammka with Jacen Solo, especially after his twin sister, Jaina, adopted the guise of Yun-Harla. At the end of the war, the Shamed One Onimi revealed to Jaina that he had come to believe her uncle, Luke Skywalker, was actually Yun-Yammka, since he alone of the Yuuzhan Vong could see her through the Force. Harrar later revealed that, in fact, there was no original god named Yun-Yammka. This deity was created by the priest caste after the ur-Yuuzhan Vong were severed from the Force and took up their warring ways.
