[I know of this book. It is a sacred tome to those who worship the Old Gods, containing the deepest secrets and most incomprehensible mysteries of the Void. Only the most devout cultists are allowed to gaze upon its pages.
Even incomplete, holding it makes my skin crawl. I must take care not to read too much of it in a single sitting.
That being said, we must find its missing pages in order to continue our research. Retrieve them from the darkest corners of N'Zoth's visions.]
