Torghn, son of Kmpok was a Klingon warrior in the House of SepIch. He was killed at his son Pok's lop'no by Qua'lon. His wife, K'Tar, survived him. His ancestors conquered Taganika, and were the inspiration for the Klingon opera Qul Tuq. At his son's Rite of Ascension, Gowron listed Torghn as one of the great warriors of the House of SepIch.
