Kahless and Lukara was a classic story in the Klingon mythology. At the dawn of the Klingon Empire, five hundred warriors assaulted the Great Hall of Qam-Chee. The city garrison was routed with only Kahless and Lukara holding their ground. They defeated the warriors and began what some considered as one of the greatest romances in Klingon history. In 2373, after sharing a holosuite recreation of this event with Jadzia Dax and discovering his feelings for her, Worf married her.
