The Book of Fury is a relatively large, tattered black book, with a stylized flame-and-sword symbol on the cover. The pages are handwritten, and some contain drawings of what appear to be weapons, anatomy, and other things. It was written by Reverend Fury as part of his quest to destroy undead. The book contains many notes on vampires: vampire lore, how to recognize vampires, how to kill vampires (by far the largest portion), and similar notes for other types of undead. There is no particular organization to the text, and liberally sprinkled throughout it are Reverend Fury’s egotistical (possibly megalomanical) ramblings, all of which generally make it sound like a particularly hellfire-and-brimstone religious text, not to mention making it very confusing to read. The Reverend will not relinquish this book under any circumstances, even though he rarely has to reference it anymore. In violent situations, he is likely to start quoting some of the more vitriolic passages.
This book has no special properties beyond being a VERY thouroughly researched manual of the undead and how to kill them in as many ways as possible.
