General Martok's elderly aide, a contemporary of Kor who helps the old warrior find his last glorious battle.
Darok is the aide of General Martok aboard the Ch'tang in Once More Unto the Breach. He is an old Klingon of the same generation as Kor and is sympathetic when the aging warrior is ridiculed after his memory fails him in battle.
When ten Dominion ships pursue the Klingon force, Darok tells Kor that Worf intends to sacrifice himself to delay them. Kor takes Worf's place and dies holding off the enemy, earning the glorious death he had been seeking.
