The Zealot Order is a warrior order of Khalai protoss. Comprised of zealots, it has its origins on Aiur, long before the Great War. The order's symbol is the Zealous Round, which represents its ideals of purity, focus, and thought. Upon initiation, every zealot traces the symbol onto their chest before taking their vows, under the light of Saalok on Aiur. Even after the Brood War and loss of Aiur, the order appears to still remain, though training is carried out on Shakuras.
