K'naiah sired Kang with the sister of the emperor of the planet Tahrn. As the tradition of Klingons living on Tahrn passed succession of that title through the sister's son, K'naiah's son would be entitled to follow as an emperor of that world and to hold a seat on the Klingon Council of Rulers. (TOS novel: Pawns and Symbols)
