The group known as the Royal Seers consisted of four seers who served as advisors to Shimrra Jamaane, the Yuuzhan Vong's Supreme Overlord, during the concluding period of the Yuuzhan Vong War. These Royal Seers were selected as a demonstration of amity towards the Elite, who had become increasingly worried about Shimrra's behavior in recent klekkets. Each of the four Ruling Castes—Warrior, Intendant, Shaper, and Priest—was represented by one of the four seers. These elderly women were covered in desiccated Yuuzhan Vong blood, which gave them a horrifying, witch-like aspect. The actual usefulness of the Seers was doubtful, given that they frequently contradicted themselves, and that Shimrra's pronouncements were considered to be the embodiment of Yun'o's desires. During the Battle of Yuuzhan'tar, when it was discovered that Zonama Sekot had provided the Jedi with living vessels, a violation of the True Way, the Seers questioned if Shimrra had misinterpreted the omens. Enraged, Shimrra commanded the Slayers to execute the Royal Seers. None of them put up a fight.
