This is a note found as a random drop from breakable bookshelves.
Fear, my brothers. Fear ye the Ch'thonian, for it is the harbinger of our sins. Speak not the name of its master, for it is the manifestation of malevolence and vile intent. Abhor the heretic, for his words are poison to the ears of the faithful. Just as evil must be purged of the soul, so the heretic must be purged of the living.
