Qam-Chee
Qam-Chee was a city on the Klingon homeworld of Qo'noS. It was there, "a thousand years ago", that Kahless and the Lady Lukara fought a pitched battle in the city's Great Hall against the soldiers of Molor. 

While the rest of the city's garrison fled before Molor's five hundred soldiers, Kahless and Lukara stood their ground and defeated the forces. Shortly after their victory, the two began their great romance, the stuff of Klingon legend. 

While helping Quark get a better feel for Klingon history in 2373, Worf described this battle vividly for him. ()
