Klingon noblewoman who married Quark to save her house and later became his lover with some help from Worf.
Grilka is a Klingon noblewoman and the widow of Kozak, head of a Great House. Kozak dies in an accident in Quark's bar, and Quark's boast that he killed the Klingon in combat brings Grilka to Deep Space Nine, where she abducts Quark and takes him to Qo'noS.
In The House of Quark, Grilka marries Quark so that the house will have a male head and cannot be absorbed by D'Ghor, a rival who has been secretly bankrupting it. Quark uses his business sense to expose D'Ghor, and Gowron grants Grilka the right to lead her house herself, after which the marriage is dissolved.
In Looking for par'Mach in All the Wrong Places, Grilka visits the station again. Worf is drawn to her, but she prefers Quark, and Worf helps Quark win her affections, coaching him through a holosuite combat to impress her. She was played by Mary Kay Adams.
