One of three unique books ("the Cataclysmic Triad") to be used for "The Rift" quest written by Randonaut. It is a tome of forbidden knowledge that was stolen from the realm of Hermaeus Mora.
https://www.tamriel-rebuilt.org/claims/headless The player finds a talking skull. It turns out to be the head of an ancestor guardian (some sort of intelligent bonewalker?) that an adventurer knocked off its body, and now it can't move around on its own. It tells the story of how the body killed the adventurer but then wandered off and fell off a cliff/into a river/etc and was destroyed. The skull asks the player to take it to its family so it can be properly reinstated.
