Forbidden Knowledge and Corruption

From publisher blurb:

There exist Things-Man-Was-Not-Meant-to-Know. Secular scholars might argue that knowledge, in and of itself, is neutral, but those who have delved the darker mysteries know better. Certain manuscripts contain knowledge so corrosive, that it is toxic to the humanoid mind. From implications of cosmic insignificance to knowledge that such insignificance may be the only thing saving us from eldritch malevolence that simply hasn’t noticed us, the further one delves into such grimly esoteric lore, the more such knowledge weighs on the mind. It frays the reader’s capacity to interact with their neighbors and slowly transforms them, drawing them inexorably into madness, damnation, or both.
