The Palace of Kahless was a landmark on the planet Qo'noS and was a structure in the center of the First City that served as the home for the First Emperor of the Klingon Empire who was Kahless the Unforgettable. Following the death of Emperor Koth, the Palace became the home of the Klingon High Council who conducted their meetings within its halls. By this point, it was a large as well as thoroughly modern structure yet maintained its ancient qualities. In 2369, the Followers of Kahless unveiled a clone of Kahless whereupon a wing was cleared out within the Palace which would serve as a ground for the new ceremonial Emperor.
