Klingon who tried to ruin and seize the House of Kozak, until Quark exposed his dishonest finances before Gowron.
D'Ghor is a Klingon in The House of Quark. After the drunken Klingon Kozak dies in Quark's bar, D'Ghor visits Quark claiming to be Kozak's brother and pressures him to keep up the lie that he killed Kozak in combat. In truth D'Ghor is Kozak's enemy and has been draining the family's wealth.
When Kozak's widow Grilka marries Quark to protect her house, Quark reviews the family ledgers and exposes D'Ghor's financial scheming to the High Council. Quark refuses to fight their duel, and Gowron, disgusted by D'Ghor's conduct, banishes him.
