Lieutenant Commander Lojur was a 23rd century Starfleet officer who served as the helmsman aboard the USS Excelsior under Captain Hikaru Sulu.
Lojur served at the helm aboard the Excelsior during its three-year mission cataloging gaseous planetary bodies in the Beta Quadrant, from 2290 to 2293. He also served at the helm during the battle at Khitomer against General Chang in 2293. (Star Trek VI: The Undiscovered Country; VOY: "Flashback")
Lojur was played by actor Boris Lee Krutonog. His accent was far thicker in "Flashback" than in
The Undiscovered Country.
The novelization of The Undiscovered Country
by Jeanne M. Dillard
established that Lojur was a Halkan
; he reappeared in her novelization of Generations
, which mentions "his family symbol, tattooed in red between his pale eyebrows," consistent with the appearance of the Halkans in TOS
: "Mirror, Mirror
", but not the character's actual appearance on screen. Peter David's novel The Captain's Daughter, on the other hand, called him a "Kothan." The Star Trek: The Lost Era novel The Sundered cleared up the discrepancy by establishing that Lojur was from a village called Kotha on Halka, and also explained how a member of a pacifist species could serve in Starfleet by establishing Lojur was exiled by his village elders in 2281 for violating their strict code of pacifism when he used deadly force against invading Orion pirates. A landing party from the USS Reliant, led by Commander Pavel Chekov, finds the young exile and takes him back to the ship.
