Toq was the child of Klingon warriors captured by Romulans in 2346 at Khitomer. Raised at the secret Romulan prison camp on Carraya IV, Toq had little exposure to Klingon culture until Worf visited the prison camp in 2369. Worf gave Toq and the other Klingons who left Carraya IV a belief in Sto-vo-kor. When he saw the power of their faith in the Klingon afterlife, Worf began questioning the strength of his own faith and found it lacking. (TNG: "Rightful Heir" )
