Shanto K'Tor was the leader of the Bur Chak kingdom, a Klingon House. By the early 2280s, Shanto K'Tor's kingdom had consolidated its power over the Klingon Empire, leading him to have control of the emperor's seat. (Ships of the Star Fleet, volume 1)
- In Star Trek comics, the Klingon emperor in the 2280s was named Kahless IV, which could be the assumed royal name of Shanto K'Tor. Both references contradict the fact that, by the time of TNG, Worf states the emperor's seat has been vacant for centuries. Its possible the Klingon leaders in question "controlled the emperor's seat" without being emperor themselves.
