B'iJik was a minor bureaucrat serving in the Klingon government on Klingon homeworld in the late 2360s. His formal title was "Junior Adjutant to the Diplomatic Delegation."
In 2368, Captain Jean-Luc Picard was faced with the need for a cloaked vessel to penetrate Romulan space. Since he had just assisted Klingon Chancellor Gowron in his fight against the House of Duras in the Klingon Civil War, Picard naturally assumed Gowron would be willing to assist in this matter. However, Gowron consistently ignored Picard's hails, as it was revealed by Worf, that Gowron was in the process of re-writing Klingon history in his own favor and Picard's arrival in Klingon space was an unwelcome reminder of the truth.
When Picard insisted on speaking with someone, B'iJik was assigned to speak to Picard. B'iJik insisted that Gowron was too busy to answer Picard personally, but offered to take a message. This offer incensed Picard, who then told B'iJik that if Gowron was too busy to help him, there were "others" in the Empire who would be more willing. Understanding Picard's veiled threat, B'iJik passed on the message and Picard was promptly supplied with a cloaked Bird-of-Prey. (TNG: "Unification I")
