The Story of the Promise

The Story of the Promise is a Klingon legend from the time of Kahless the Unforgettable. According to the story, after Kahless had united Qo'noS to form the Klingon Empire, the time came for him to depart. The people begged him not to leave, however, but Kahless was undeterred. He said he was going ahead to sto-vo-kor, but that he would one day return. He pointed to a star in the heavens, and instructed his followers to look for him "on that point of light".

Klingon clerics would later establish a monastery on the planet Boreth, which orbited the star that Kahless had pointed to, in order to await his return.
