According to legend, Yun-Yuuzhan sacrificed his body parts to form the universe, the lesser gods, and the Yuuzhan Vong. In honor of his sacrifices, the Yuuzhan Vong in turn sacrificed body parts—and living beings—in remembrance of his act of creation. He was revered formally on the holiest days on the Yuuzhan Vong calendar; such dates were the occasions on which rites and sacrifices devoted to him were conducted.
