The cha'nob were traditional Klingon gifts brought to a boy's second Rite of Ascension by honored guests. Gowron brought many to Pok, son of Torghn on his special day. Pok received an Acta crystal and the score to the opera of Qul Tuq. One of the gifts held a Romulan assassin probe which killed Pok's father. (ST novel: Klingon)
