Pirak was a Cardassian gul who commanded a weapons depot outside the Bajoran city of Hathon during the Cardassian occupation of Bajor. He committed many acts of brutality, including the execution of fifteen Bajoran farmers for failing to display a Cardassian banner.
As a result, Pirak became the target of an assassination by the Shakaar resistance cell. Trentin Fala told the resistance fighters how to bypass the security systems, Latha Mabrin built the plasma charge to be placed outside Pirak's residence, and Kira Nerys planted the bomb while Furel and Lupaza stood guard. The resulting explosion vaporized the east wing and killed twelve Cardassians, including Pirak's entire family. Twenty-three others were crippled, including Silaran Prin, who years later sought revenge against all the Bajorans involved. (DS9: "The Darkness and the Light")
