Aldaris was a Khalai protoss of the Judicator Caste. He was a firm believer in the Khala and did not hesitate to judge others through a strict interpretation of its tenets. Later he would ally with the Dark Templar out of necessity but the lack of trust would ultimately play into the hands of Sarah Kerrigan. A subservient and fiercely loyal Judicator to a fault, Aldaris held the will of the Conclave in the highest regard and was an avid defender of the Khala.
