Torin was a Klingon monk, who together with Koroth was responsible for creating a clone of Kahless in 2369.

When Worf set out on a pilgrimage on Boreth, he told Torin of a vision about Kahless from his youth. This information was imprinted into the Kahless clone by Torin, so Worf believed the clone to be the real Kahless.

Torin and Koroth later briefed the clone on the current political situation and tried to convince him to take over the Klingon Empire. (TNG: "Rightful Heir")
