The Seeker

The Seeker was a clairvoyant and soothsayer on the planet Ribos, used by the city guards of Shur to seek criminals. While her divinations were accurate, the source of her psychic powers was not clear. She put on a rite dealing with bones.

After witnessing her abilities, the Graff Vynda-K forced the Seeker to lead him into the catacombs. In doing this, she prophesied the death of herself, the Graff, and all of his men; this was an accurate prediction.
