The Paq'batlh is a large series of ancient Klingon scrolls and religious texts, that, among other things, passes on the stories of Kahless. Along the side of the scrolls are 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 are Klavek's tomes. The Eleventh Tome of Klavek describes how Kahless came back from the afterlife, and had kept a scar to show that what he'd experienced was real, so that he may save the soul of his brother. (VOY: "Barge of the Dead")
