Here I would like to discuss fan-made Tomes of Corruption, as well as to present our creations.

I've created three so far in my campaign. They are all largely based on material from H.P. Lovecraft's Tales of the Cthulhu Mythos (arguably a major source of inspiration for the setting of this RPG).

Fluff wise, these books would definitely have other sinister side effects on those who read them. Those details would be up to the GMs.

De Vermis Mysteriis (High Gothic for Mysteries of the Worm)

Description: "To you, the great Not-to-Be-Named, signs of the black stars, and the seal of the nine times blessed Tsathoggua". The book contains spells and enchantments, particularly those that can summon strange entities. One such spell, included in a "chapter dealing with familiars," summons the titular "Shambler from the stars". The book also contains references to "such gods of divination as Father Yig, dark Han, and serpent-bearded Byatis", all ancient and extremely powerful Horrors of Tzeentch and major members of his pantheon.

Effects: To gain any of the benefits of De Vermis Mysteriis, the owner must read the book entirely. Doing so grants 2d5 Corruption Points. The book allows the owner to purchase the Elite advances of Forbidden Lore (Daemonology) , Forbidden Lore (Daemonology) +10 and Forbidden Lore (Daemonology) +20 , at the experience costs of 100, 200 and 300 respectively. Also, use of said book for investigative research regarding Forbidden Lore (Daemonology) and Forbidden Lore (Warp) reduces the difficulty (and thus the time required to perform such research) by one step. Such use requires a WP test or the reader gains 2 Corruption points.

The Pnakotic Manuscripts

Description: The Pnakotic Manuscripts predate the origin of man. The original manuscripts were in scroll form and were passed down through the ages, eventually falling into the hands of secretive cults. A strange Xenos race identifying themselves as the Yith are believed to have produced the first five chapters of the Manuscripts, which, among other things, contain a detailed chronicle of the race's history. The Pnakotic Manuscripts were kept in this Xenos race's library city of Pnakotus (hence the name). They cover a variety of subjects, including descriptions of powerful Lieutenants of the Ruinous Powers: Chaugnar Faugn and Yibb-Tstll, Xiurhn, Rhan-Tegoth, and others. Most importantly, it details the downfall of a highly developed race into Warp perversion, civil war and mass genocide.

Effects: To gain any of the benefits of The Pnakotic Manuscripts, the owner must read the book entirely. Doing so grants 2d5 Insanity Points. The book allows the owner to purchase the Elite advances of Forbidden Lore (Xenos) , Forbidden Lore ( Xenos ) +10 and Forbidden Lore ( Xenos ) +20 , at the experience costs of 100, 200 and 300 respectively. Also, use of said book for investigative research regarding Forbidden Lore ( Xenos ) and Forbidden Lore (Legend) reduces the difficulty (and thus the time required to perform such research) by one step. Such use requires a WP test or the reader gains 2 Insanity points.

The Daemonolatreia

Description: The Daemonolatreia explains the horrors and dangers of the power of witches and sorcerors, how to distinguish them, and how to torture and destroy them. It also details different kinds of mutations, their possible natures, as well as intricate diagrams of mutant fetuses which had become corrupted in utero .

Effects: To gain any of the benefits of this book, the owner must read the book entirely. Doing so grants 1d5 Insanity Points and 1d5 Corruption Points. The book allows the owner to purchase the Elite advances of Forbidden Lore (Psykers) , Forbidden Lore ( Psykers ) +10 and Forbidden Lore ( Psykers ) +20 , at the experience costs of 100, 200 and 300 respectively. Also, use of said book for investigative research regarding Forbidden Lore ( Mutants ) and Forbidden Lore (Psykers) reduces the difficulty (and thus the time required to perform such research) by one step. Such use requires a WP test or the reader gains 1 Insanity point and 1 Corruption point.

Good stuff, there. I like that there's an established format for what a Forbidden Tome does (Forbidden Lore, +10 and +20 made available for purchase, research bonus for 2 Lores, cost of 2d5 and 2 respectively, split over corruption and/or insanity). My only nitpick is that a reading an entire tome on the nature of daemons would surely drive whoever braved such an act slightly mad rather than just corrupting them. It might also be worth considering unfortunate and unforeseen consequences for those who read the more powerful supernatural tomes. In the first of the Grey Knights books the most dangerous of tomes were read remotely by servitors who were immediately destroyed afterwards due to the extreme peril of even glancing at the pages of such a thing.

Good Catch Necrozius I meant to grab your thread and bring it over as well (some parts of the old site are a bit knackered so its taking a while) but here is T.S' Forbidden Tome.

I trust there are some Call of Cthulhu fans among us? You guys should have fun with this one: Eusi Kitarun Arguably the most infamous tome ever produced within the Calixis Sector, the Eusi Kitarun is a phenomenally complex but exceedingly accurate treatise on the warp, how it interacts with realspace, and hints about the denizens that dwell within it. There are chapters devoted to each of the Dark Gods, though they are deeply couched in metaphor, as well as an extensive discussion on how the malignant powers of the Immaterium helped bring about the Horus Heresy. There are also a number of learned comments on how to counter the influence of the warp by using certain arcane designs during the construction of both ships and buildings. The author of the Eusi Kitarun is undeclared and unknown, though comments throughout the book have lead the few learned Inquisitors that have perused it to conclude that its creator was a heretek of some stripe as the extensive scientific accuracy of the tome harkens one to the mind of the Adeptus Mechanicus. The Eusi Kitarun is known to have come from the Calixis Sector only because the pages of the dozen or so copies that the Inquisition has hunted down are made from trees native to Malfi. It is unknown just how many copies of the work were actually produced. For obvious reasons, the tome is proscribed by the Inquisition. Still, a copy turns up from time to time in the black markets of the Malfian sub-sector, where they invariable sell for a high price. Game Effects: Reading the Eusi Kitarun gives one a disturbing amount of insight into the warp – but it is a difficult text to master. It is written in an old form of High Gothic, requiring literacy in that language to read properly. The would be reader must then succeed at a Difficult (-10%) Intelligence Test . Failure means the esoteric nature of the text is beyond the reader, success means that they gain 1d10 Insanity Points and acquire the skill Forbidden Lore (The Warp) . This is more than enough for most readers, who will hurl the text from them, but a rare few will persist. 9 Months of dedicated study allows a standard Will Power Test. Failure means there is nothing more to be gleaned, but success means the reader has twisted their mind around the deeper insights contained within the book. The character immediately gains 1d10+4 Corruption Points and the skill Forbidden Lore (Daemonology) .

Auksinis Alfabetas Medicina

The golden tome of medicine, in it the all-inclusive knowledge of the holy form of man. Be it extraordinary, mundane or heretical. Knowledge gathered and guarded over centuries by the cult of Penitus Rememdium. The tome itself is far from golden as it is a vast heap of notes bind together by a many times extended leathery cover, on in the crest of Penitus Rememdium. According to lore/legend the tome was lost in the Angevin Crusade when the cult of Penitus Rememdium was put to death, its current location is unkown.

Game Effects: Reading Auksinis Alfabetas Medicina requires a literacy, High Gothic check (-10% intelligence, 0% if the reader also has a high logic skill, +10% if reader also has advanced Medicae skill. ) Reader must spent atleast 1-2 month translating and cataloging. On success the tome grants the reader 1d10 insanity points, 1d5 corruption points and permament +10% on medicae checks made on a human. Book contains helpful insight on Forbidden lore (heresy) and Scholastic lore (chemistry & occult) . Also consulting the book degreases very hard (-30%) medicae check to hard (-20%).

Yey...! Pardon my english its not that good ... Feel free to modify this crap at will.

One of the best fan-made material on Dark Reign is this collection. Which of them are forbidden you must find out for yourself.

I am not the author of course and you might have to become a member to be able to down load it. It is worth it though.

Ooh this stuff is good. May I use your rules for actually READING the books for the tomes that I created? IE, requiring Literacy and High Gothic checks, etc...?
