->''"I have examined this book, perused its pages, and inspected the reflections of those despicable authors who have added their peculiar insights into this most foul work, yet I refuse to see this tome as evil. This book is just a book. Where evil exists in regard to this tome is in the intent behind its use. I can imagine how a wretched man with darkness in his heart might find the contents here instructive to feeding his vile ambition. Yet can we not also see how a virtuous man might scan these same pages for insights into how he might triumph over that same darkness? This book is a tool and nothing more. Do not be put off by the sharpened edges and the curious odors wafting from its pages."''

->'''[[BadassBookworm Urag gro-Shub]]:''' An [[TitleDrop Elder Scroll]] is an instrument of immense knowledge and power. To read an Elder Scroll, a person must have the most rigorously trained mind, or else risk madness. Even so, the Divines usually [[BlindSeer take the reader's sight as a price.]]\\
'''[[PlayerCharacter Dragonborn]]:''' A price for what?\\
'''Urag gro-Shub:''' The simplest way to put it is "knowledge," but there's nothing simple about an Elder Scroll. It's a reflection of all possible futures and all possible pasts. Each reader sees different reflections through different lenses, and may come away with a very different reading. But at the same time, all of it is true. Even the falsehoods. ''Especially'' the falsehoods.\\
'''Dragonborn:''' Who wrote the Elder Scrolls?\\
'''Urag gro-Shub:''' It would take a month to explain to you how that very question doesn't even make sense. The Scrolls exist here, with us, but also beyond and beneath. Before and after. They are bits of the Divine made substance so we could know them... sorry, talking about the Scrolls, you usually end up in irritating and vague metaphors like that. Some people who study them devoutly go mad.

->Upon rereading the pages of the book compiled previously (which has mouldered in a lead-lined box since publication) I noticed a subtle change had occurred to the pages. When I opened the covers, I noticed a faint odour. At first, I thought it was quite a pleasant smell, in fact, I felt a little light headed as it entered my lungs. But after a few breaths, I felt a dull pain behind my eyes, and waves of nausea rolled over me; what had previously been an intoxicating perfume quickly turned sour. Working with the manuscript again became a horrible experience. I [[MushroomSamba experienced visions, disturbing and arousing in equal measure]], and sleep became impossible to find. When it did overtake me, my dreams were filled with [[EroticDream viler visions and debauchery]]. I was most glad when it was over. I have heard tell that there is an edition of this book that fell into the hands of a daemon-worshiping cult in Wolfenburg. They cast foul magic on it and wrapped the book in the skin of a daemon; [[BrownNote even to touch this edition is to curse yourself]].

->It is said that amongst those Seekers After Truth who have gazed upon [[MagicalLibrary these profane volumes]], some [[GoMadFromTheRevelation were driven mad immediately]], while others [[EyeScream tore out their own bloodied eyes]] rather than peruse the writhing calligraphy a heartbeat longer than they had to. And on these forgotten shelves, amongst those titles that should never be named, there is one grimoire that is said to be the most hideous of them all. That book is the very [[NamesToRunAwayFromReallyFast Lexicon of Fear]] itself. Within its seductively soft and supple pages are the [[BrownNote words of terror]] themselves, made manifest by the tales they may recount to the unwary reader.
-->--''Horrorology,'' by Stephen Jones

->These infamous "black books" distill the essence of the Pit through the written word. Bound in [[GenuineHumanHide ominous leather]] covers (many of which obviously come from [[HumanResources human "cattle"]]) and filled with odd glyphs and strange designs, a grimoire is more than just a book. Within its pages, mysteries are revealed in [[BlackSpeech esoteric language]]. A reader who manages to plumb the book's obscure symbolism and unearthly designs learns just a little bit more about Heaven, Hell and the denizens of both.
->The instruction is not as easy as it sounds. Madness lies on each page of any grimoire worth the name. Some of these books feature living diagrams, foldout pages, captured winds, and other uncanny phenomena. And then there are the revelations themselves - devil-summoning rites, the True Names of angels, corpse-poetry and [[BrownNote brain-crushing metaphysics]]. A person who reads a grimoire is at the very least disturbed; one who actually ''understands'' it is a step or two closer to insanity.
