Kor, son of Rynar, the last son of the House of Kor and descendant of the Klingon Imperial Family, was among the most influential warriors and respected military leaders of the Klingon Empire during the late 23rd and early 24th centuries.
Kor was descended from Klingons affected with the augment virus created in 2154, a product of 22nd century Klingon genetic engineering. By the 24th century he was cosmetically indistinguishable from an average Klingon. It is unclear if he was ever subject to the physical and mental weakening effects of the virus.
Throughout his illustrious career, Kor played key roles in many legendary battles against the Federation and Romulan Empire. Kor's influence in the Empire would elevate him to the status of Klingon Dahar Master.
