Tath Ki, also known as the Contemplator, is one of the Elders of the Universe, a group of ancient beings who have lived since the dawn of the universe.
Almost immortal, the Contemplator has dedicated his life to develop the powers of mind and spirit, and using them to probe the mysteries of the universe. He is in complete harmony with the cosmos, to a greater extent than any other living being, believing that each of his actions is dictated by the cosmos' "desires". Thus, he never feels anxious. Unlike other Elders, the Contemplator is a quiet pacifist with soft voice and an essentially benign being (although insufferably vain).
