A Bajoran prylar who served as the Vedek Assembly's liaison with the Cardassians during the Occupation and who hangs himself on Deep Space 9, confessing that he betrayed a resistance base in the Kendra Valley.
Prylar Bek is a figure central to the second-season Deep Space Nine episode The Collaborator, seen in Vedek Bareil's Orb visions and in the story of his death. His confession stated that he gave the Cardassians the location of a resistance cell, leading to the deaths of forty-three Bajorans, among them the son of Kai Opaka.
In 2370 the exiled collaborator Kubus Oak tells Vedek Winn that Bek acted on the orders of Bareil, her rival in the election for Kai. Kira investigates and finds that records have been altered.
The truth is that Opaka herself revealed the base to save a far larger number of lives. Bareil accepts the blame and withdraws to protect her memory.
