Corysta

Corysta was a Bene Gesserit sister who had been sent to the punishment planet of Buzzell to work on harvesting cholister-producing soostones.

Sent to Buzzell
During the time of the Return of the Honored Matres, Corysta had been ordered to seduce and conceive a child with a particular nobleman from a wealthy family. But contrary to the wishes of the Sisterhood, Corysta had decided to try to keep her child after giving birth to her. The child had subsequently been taken away from Corysta, and she was sent to the water-world of Buzzell to live with other acolytes who needed penance.
