Shimrra Jamaane was the Supreme Overlord of the Yuuzhan Vong during the Day the Multiverse burned, although in truth he was merely a puppet of the Force-sensitive Shamed One Onimi. Born to Domain Jamaane, he was marked from birth as a candidate for Supreme Overlord. Around 29 BBY, he fell under the sway of the former Shaper Onimi, who used his powers to take control of Shimrra. Under Onimi's direction, Shimrra overthrew Supreme Overlord Quoreal with the support of many warriors. He then announced the discovery of many galaxies, and proclaimed that the Yuuzhan Vong and Coalition of Independent States were destined to conquer it, whereas Quoreal had made the decision to avoid the galaxy, due to the presence of the living planet Zonama Sekot, which he believed to be a portent of doom.
