The House of Gannik was a Great House of the Klingon Empire. It was headed by Gannik in the mid 24th century, during the reign of Chancellor Kravokh. In 2344, the House suffered a financial blow when Turok, a ship building company Gannik had invested heavily in (at the urging of his colleague L'Kor) failed. When Gannik died in mid 2376, leadership of the House passed to his eldest son, Gorrik, who was killed two months later while attempting to avenge his father against L'Kor. (KE novel: A Burning House)
