Pa'u Bitaal was the spiritual counselor of the Delvians, and the personal teacher and lover of Zotoh Zhaan. When his tenure was over, however, he refused to resign from his position and instead hired the Peacekeepers to help him take control of Delvia. Liberals and free thinkers were rounded up, including Zhaan's father, and placed in prison camps.
Fearing for her own life, and realizing she could free Delvia from tyranny, Zhaan shared Unity with Bitaal and killed him during the act.
Bitaal is seen in a flashback during an episode of Farscape.
