Paq'batlh
The Paq'batlh was a large series of ancient Klingon scrolls and religious texts, that, among other things, passed on the stories of Kahless. Along the side of the scrolls were icons of the Klingon culture, such as bat'leths, d'k tahgs, and the emblem of the Empire.

Among the scrolls in the Paq'batlh were Klavek's tomes. The Eleventh Tome of Klavek described how Kahless came back from the afterlife, and had kept a scar to show that what he'd experienced was real, so that he could save the soul of his brother. ()
