Among the Warhammer fandom there are a small number of long out-of-print books which have become almost treasured relics. There are certainly novels among these, but the big ones were often the sourcebooks. Things like the Imperial Infantryman's Uplifting Primer, Xenology and Tactica Imperialis were among the big ones. Most were excellently written, but the one which seems prized above almost all of them was the Liber Chaotica.

So, you might be wondering just why we have never covered it before now given how much of a fan I am of this stuff. Well, there's a very good reason for that: I could never get my hands on any of the volumes. Honestly, they always cost an arm and a leg (proverbially, Chaos did not require a flesh sacrifice for once) on eBay and most were difficult to get hold of. However, Black Library's thankful change of heart in reprinting older works has paid off, so now I have a full copy in front of me.

So, does the book live up to its reputation:

Short answer: Yes.

Long answer: ... Well, let's dive into it.


The Synopsis:

The Liber Chaotica is the Necronomicon of the Warhammer Fantasy world. Containing the knowledge gathered by Richter Kless, it retains four volumes on each of the primary Chaos Gods. Examining their natures, forms, and champions, it combines the madness of a man gaining knowledge of beings beyond his comprehension with glimpses into aspects of Chaos which are often glossed over. Yet with all things involving Chaos, madness and half-truths dominate the pages, and you can never be wholly certain just what information can be relied upon.


The Good:

To cite the obvious first: The book has stunning art. While it reuses many elements from other past armybooks, codicies and the like, it also has a plethora of its own designs. Each of these follows in the John Blanche style of sketchy stylised horror, and it fits in perfectly with the madness of the book in question. Atop of this, even when you are skimming through, the various displays of papers layered upon one another gives it a great visual distinction. Honestly, it's a fantastic combination of parchment, layers of scraps and aged documents with handwriting between older linkwork. You could easily skim through the pages and still find engagement just in the visuals.

Of course, even without the visuals themselves, the content would still more than justify the book's price. Liber Chaotica delves headlong into both the lesser known elements of Chaos and the symbolism behind it. While all of this has a "By the way, this guy is insane" escape clause hanging over it, the details present are both broad and deep. We see everything from outlines of the early Chaos groups which form up most of Khorne's marauders to the underlying corruption of Nurgle. It explores and outlines how the very nature of Chaos has a grip on varied societies across the Old World and other regions, but it also goes further. Even without these, the tomes also explore how Chaos feeds upon actions of mortals, and utilises both positive and negative emotions to feed themselves. It's a great depiction of each element, and it shows just why there has never been some final victory against the gods.

Yet perhaps the best factor within the book is how it tries to be vague on so many points. While it outlines a great deal of lore from many viewpoints, and covers familiar territory, it nevertheless avoids pinning down Chaos to a few distinct elements. It reintroduces the purely chaotic side of Chaos itself, and build upon that to some degree. You can clearly see how broadly applied many defining aspects of each god truly are, and how everyday life can so easily fuel them. This is then further exemplified by the listings of individuals and champions who assist each god's cause, showing how anyone can easily fall prey to their wills.

Saying more would sadly end up spoiling the book but, even when Liber Chaotica does cover obvious points, it still goes into great detail over them. Even the most basic of ideas can emerge in here with a new perspective or idea, and it's something helped by how the in-universe writer garners visions of these beings. It also further solidifies a link that was thought to have been long abandoned, as he starts to see increasingly less vague visions of (what looks very much like) the Horus Heresy.


The Bad:

This might be surprising to some, but the trouble with madness is that it can be very hard to follow. The patchwork combinations of story elements, other documents and ideas scribbled down from half-seen dreams creates atmosphere. It also helps to evoke a far more alien and genuinely disturbing element to Chaos that the faction sometimes lacks due to overexposure. Yet, even with that said, you can find yourself re-reading certain bits to just try and confirm the information present. There's a very fine line between being unreadable due to being art, and just being unreadable.

The incoherent quality of certain bits is only further exaggerated by certain stylistic choices throughout the book. The font used for Kless' scribblings are difficult to read at the best of times, and the problem is only made worse by their small size. However, even without that, you then have bits where it is fitted between lines in books, or on backgrounds which make it genuinely unreadable. Thin red lettering simply does not work when it's against a stark black and white image.

Finally, the book is also irritatingly structured in how it combines its volumes. One after the next is fine, but they retain the weaknesses of the original individual ones as well. As such, the likes of Khorne and Nurgle both retain weak opening and middle parts respectively. It can make the quality seem to vary heavily if you are going from cover to cover and, even with the benefits of coloured pages, the lack of an index only exaggerates the problem.


The Verdict:

Even with its few issues Liber Chaotica still remains a very strong addition to the Black Library's volumes. The newly printed hardcover compilation is more than worth your time, and even just as a general reference book it offers an immense wealth of background knowledge. It's just a damn good book which is extremely well thought out, and even has a back-door "ignore me" clause in the form of insanity if you don't like its contents.

Given that this is likely to be a limited run, I would definitely suggest getting this one while it's still on shelves.

Probably my favorite Warhammer book. If you have a taste for endlessly reading up on religion/mythology and want to see someone do that in a fantasy setting, I'd probably recommend this text, because it definitely caught my eye when I was a teenager. Really dragged me into the setting, in that sense. Still good on a reread, too.

libro che raccoglie di fatto i 4 libri iniziali sul background delle divinità del caos di warhammer. Se piace l'universo di Warhammer questo è un libro da avere e leggere. di certo grafiche e composizioni sono state fatte in modo accattivante e catturano molto

This is the best book about the Chaos Gods and the second best book about Chaos in general after «Tome of Corruption» (WFRP). Extremely well narrated and very well thought. The author have succeed to present the nature and aspects of the Chaos Gods and their followers like never before. This is a classic for Warhammer.

One could think that the Chaos and the Chaos Gods of Warhammer would present the perfect setting to get stories of anti-hero in abundance. However, so far I found none that was very satisfying. «Palace of the Plague Lord» and «Blood for the blood god» are set in the Chaos waste, but they are not that much sinister because they are rather conventional after all. The second one is not totally boring, but not that great either. It give you a fun trip, but nothing more.

To get a proper fix of vileness and horror from the Ruinous Power, the Warhammer fan will have to find it outside the Black Library novels. The coveted heretical manuscript lay with this book. Lucky you, Black Library reprinted the book in november 2009 in hardcover, so that it can endure more mistreatment and compulsive reading usage.

I can't recommend this magnificient book enough. Like I said, it is the best book about the Chaos Gods and their symbolic ever written so far. It's not a novel, but it is neither a book for the tabletop game or the roleplaying game. There is no statistics and such into this book. It content and structure are purely literate. The goal of the book is to develop and to dig the symbolic and the meaning associated to each Chaos Gods. It also cover their minions and followers, but they are used as a mean to explain and to push further the psychology and implications associated to the the four Chaos Gods motto (Blood, Pleasure, Decay and Change). It present the information as if it have been written by different characters and scholars who would have collected thoughts, interviews reports and evidence on the topic. In that sens, it is a little bit like a collection of short fictions on a common topic. If you like the universe of Warhammer or if you are a fan of fantasy literature, you will enjoy this reading for sure.
