Cavern of Despair

The Cavern of Despair was a supposed place thought to exist by the Klingons for those who had died and been forgotten.

In 2377, B'Elanna Torres recalled and told Kohlar that she had not made a plea for her deceased Klingon grandmother L'Naan since she was a child. He then prayed to Kahless the Unforgettable himself to lift L'Naan and others from the Cavern of Despair and reveal himself to them in his full glory. Klingons believed that the dead could not rest in Sto-vo-kor, unless the living honored the memories of them, otherwise they would reside in the Cavern of Despair.
