Tenavik was a 23rd century Klingon and the son of Voq and L'Rell. (DIS: "Through the Valley of Shadows") He was conceived shortly before Voq's transformation into a Human. Like Voq, he too was an albino.
Knowing she could not be pregnant while carrying out her duties, L'Rell had the embryo gestated ex utero and kept him secret, guarded by Ujilli at the residence of the House of Mo'Kai on Qo'noS. In 2257, Kol-Sha of the House of Kor abducted the child and tried to force L'Rell to abdicate, so he could become Chancellor. After Kol-Sha was defeated, the baby was taken by Ash Tyler to be raised as a monk at the monastery on Boreth, without ever knowing either of his parents. (DIS: "Point of Light")
