House of Grilka

The House of Grilka (formerly the House of Kozak and the House of Quark) was a Klingon Great House. Due to financial machinations, the House of Kozak was in danger of being repossessed and Quark saved the House through a forced marriage with Grilka. After D'Ghor was discommended, the House of Quark passed under Grilka's hands. 

Worf commanded the House Fleet of Grilka during the Evacuation of Romulus.
