Tumek in 2371.
Tumek was a Klingon man, and the most trusted advisor to Grilka. He officiated at Grilka's and Quark's brek'tal ritual. He along with Quark help her retain her house and standing in the Klingon Empire when her husband, Kozak was accidently killed. When he and Grilka visited Deep Space Nine, he discouraged Worf from courting Grilka. Tumek said that since Worf is dishonored among Klingons, Grilka can never mate with him. Tumek insulted him by telling him that he had become too accustomed to human ways and knew nothing about how to pursue a Klingon woman.
