Captain Koren is the commanding officer of the flagship of the Klingon Defense Force, the I.K.S. Bortasqu'. She is the daughter of Grilka of the House of Grilka, half-sister to K'Dhan, as well as step sister to Alexander Rozhenko and step daughter of Worf.
Koren is said to be a talented captain who is capable of making the most out of limited resources.
Koren was born during the Dominion War to Grilka and J'Nek, a warrior from Grilka's ship who later died in the war. She grew up during a low point in House Grilka's fortunes, but began learning of battle and honor from her adoptive father as well as her mother after Grilka married Worf of the House of Martok. Consequently, Koren joined the Klingon military in order to honor her House and the warriors who died in its service.

- “A Step Between Stars”: The Bortasqu' under Captain Koren assists Federation and Romulan Republic players in the Jenolan Dyson Sphere against the Undine. After the immediate threat is over, Koren claims the Jenolan Sphere for the Klingon Empire, provoking a verbal confrontation between the three powers.

- “The Khitomer Discord”: After J'mpok dishonorably accuses the player of betraying the Alliance, Koren will side with Klingon-aligned player characters against the others, where as she will side with J'mpok against Federation-aligned characters. Following the ensuing battle, Koren is impressed by their honorable actions of Klingon-aligned players and informs that J'mpok would soon declare everyone an enemy of the Empire, advising them to leave Khitomer System, lie low and wait for her signal when it is safe to return.
- “A Day Long Remembered”: Two weeks following the fall of J'mpok, Koren is present at the celebration event in the Great Hall celebrating with Worf and Martok.
- “Day of Honor”: In 2409, KDF players visit the bridge of the Bortasqu' at Ganalda Station and meet with Koren and the rest of her crew.
- In Tales of the War #19, Koren commands the Bortasqu' in combat against Herald forces, informing Doctor Harza-Kull of wounded being sent his way.
- As her mother, Grilka, married Worf of the House of Martok, neither Koren's House-affiliation nor the actual status of the House of Grilka are known.
- Koren's appearance in "Sphere of Influence" and all successive missions was changed from how she was first seen in 2013's "Day of Honor". She previously had an appearance more closely resembling a generic female Swordmaster NPC.
- Koren's hair was slightly improved with Season Twenty: House Divided as part of the Year of Klingon updates. Her voiceovers have also been changed from Secunda Wood to Mara Junot. With the remaster of the Fek'Ihri Return arc in Season Twenty-two: House Reborn, Klingon players canonically meet her (before the Solanae Dyson Sphere arc) during this story arc.
