Seer was a rank of the Priest caste of the Yuuzhan Vong. A seer was one who took the auguries of the Gods, interpreted signs, and pronounced when the Yuuzhan Vong would be ready for a battle. Seers were often female and were often covered in black Yuuzhan Vong blood.
There were variations upon the position of seer among the ranks of the Yuuzhan Vong. One such variation was that of the warrior-seer, who provided both religious and tactical advice to senior Yuuzhan Vong commanders. A quartet of Royal Seers also accompanied Shimrra Jamaane, the Supreme Overlord of the Yuuzhan Vong, during the final days of the Yuuzhan Vong War.
