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 she 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")
Tenavik appears in the "House Reborn" update of Star Trek Online released in January 2021; he is voiced by Sam Witwer, under the guidance of Kenneth Mitchell (who could not reprise the role due to his progressing ALS). Tenavik appears briefly in the Boreth monastery during the revamp of the "Fek'Ihri Return" storyline, when the Klingon player character must go into Gre'thor to battle the vengeful spirit of Molor. He plays a more significant role in the episodes "Knowledge is Power" and "Leap of Faith". When the Empire is fractured by the self-declared Emperor J'mpok, Matriarch J'Ula of House Mo'Kai seeks out Tenavik and experiences a time crystal vision, where she witnesses a fiery warrior wielding the Sword of Kahless (at that time carried by General Martok). The warrior of fire is Tenavik's mother, L'Rell, whom Tenavik and the Followers of Kahless eventually clone to replace J'mpok. When her soul does not return to her body, however, Tenavik guides the player and their allies back to Gre'thor to find her.
