The Wozgor were a members of a sophisticated human culture about which not a lot is known, only what is inscribed on tombstones in their necropolises remains. Eltibald studied those inscriptions in his investigations into the curse of the Black Sun.
Eltibald wasn't mad at all. He deciphered the writing on Dauk menhirs, on tombstones in the Wozgor necropolises, and examined the legends and traditions of weretots. All of them spoke of the eclipse in no uncertain terms. The Black Sun was to announce the imminent return of Lilit, still honoured in the east under the name of Niya, and the extermination of the human race. Lilit's path was to be prepared by "sixty women wearing gold crowns, who would fill the river valleys with blood".
The surviving writings found on the Dauk menhirs and tombstones found in Wozgor necropolises formed the basis of several prophecies and divinations (vide: "The Prophecy of the Black Sun"), which remain questionable to this day (vide: "The Mania of Mad Eltibald"). Some scholars stipulate that the Wozgor and Dauk beliefs remain alive in the form of the religion of Melitele and lesser cults (cf. Coram Agh Tera and Veyopatis). The events which led to the extinction of both peoples remain sharply disputed among scholars."
