Or'Eq was a Klingon warrior and follower of T'Kuvma. He was the brother of Rejac.
In 2256, after Rejac was killed, his position of Torchbearer was due to pass to Or'Eq. However, Or'Eq had misgivings about whether the Great Houses would answer T'Kuvma's summons. T'Kuvma declared that Or'Eq had dishonored himself, and gave the Torchbearer role to Voq. (DIS: "The Vulcan Hello")
Like many of T'Kuvma's (former) followers, Or'Eq found himself in the service of General Kol. Or'Eq was serving on the Sarcophagus, under Kol's command, when the ship was attacked by the USS Discovery. Or'Eq perished along with Kol and the rest of the ship's crew, when the Discovery was able to penetrate the Sarcophagus cloaking device and destroy the vessel. (DIS: "Into the Forest I Go")
Or'Eq was played by regular guest actor David Benjamin Tomlinson who portrayed another Klingon in DIS: "Will You Take My Hand?".
