Boreth Monastery

The Boreth Monastery is a monastery established by the Klingons. Shortly before his death, the original Kahless pointed at a star in the skies over Qo'nos, and told the Klingon people that he would return there someday. The Klingons later came to Boreth, which orbited the star Kahless had pointed out, and established the Boreth Monastery. (TNG novel Kahless and episode Rightful Heir).

The clerics at Boreth, seeing the decay in Klingon society, decided to recreate a clone of Kahless, using genetic material that had been preserved over the centuries. They programmed this clone with memories from the original Kahless, and had him appear to Lieutenant Worf, who was attending a retreat on Boreth. Later, the deception was discovered. However Worf felt that the clone had an important role to play in rebuilding Klingon society, and proposed naming the clone as Emperor. (TNG episode Rightful Heir).

Following the destruction of the USS Enterprise (NCC-1701-D), Lieutenant Commander Worf returned to Boreth for an extended period. (DS9 episode The Way of the Warrior).

Boreth was the site of a battle between forces loyal to Chancellor Martok and those loyal to Gothmara. Martok confronted and killed Gothmara in the monastery. (DS9 novel The Left Hand of Destiny).
