Yuggya Chants
Description
The tome Yuggya Chants is written in English by an unknown author, requiring about 11 weeks to study and fully comprehend, with a minor loss of sanity and minor increase of Cthulhu Mythos lore, apparently pertaining to the Yuggya and their religion (probably contact spells for Ubb, Ythogtha, and Zoth-Ommog?)
