A Klingon world where the clergy awaited the return of Kahless.
Boreth is a Klingon world which is home to a monastery of the faithful devoted to the memory of Kahless the Unforgettable, the founder of the Klingon way of life. The monastery is a quiet and remote place, reached by travellers who wish to honour the legendary Emperor.
According to the legend, Kahless promised to return to Boreth, and the monks have waited for that return for centuries. The world is a place of devotion, pilgrimage and reflection, which stands in contrast to the stereotype of the Klingons as pure warriors. It shows the spiritual side of a culture often defined by its battles.
The planet features in the Next Generation episode Rightful Heir, in which Worf visits the monastery in search of spiritual answers. The monks reveal that they have created a clone of Kahless, and Worf takes him to the Klingon High Council, where he is installed as emperor. The story raises questions about faith and the nature of legend, and shows the Klingons' complicated relationship with their traditions.
