“Fierce and savage to the extreme, the gnoll race finds its main reason for existence in the most vile acts and indiscriminate barbarism. But now you finally have a weapon to defend yourself.”

This book contains all the necessary information to uncover the secrets of the gnolls, to flush them out, capture them, and annihilate them. However, this book might also succeed in convincing you to join them to fight their war ...

The book is part of the Speculum Naturale series, specifically the Libellus Sanguinis collection, and was found in the library of an ancient monastery. Its compiler reveals the arcana of a monstrous race long belittled and underestimated: the gnolls. This Libellus Sanguinis describes the characteristics, psychology, and society of the gnolls, paying particular attention to the religious cults that distinguish this race, and accurately addressing the military capabilities and the peculiar fighting style of the gnolls.

Furthermore, you will find ideas for adventures centered around gnolls, and an accurate description of a typical gnoll outpost, which you can choose to conquer or, if you wish to play gnoll characters, defend from adventurers seeking new challenges.

Available in a new practical and economical format, this d20 accessory is suitable for anyone who wants to add depth to their campaigns and prefers story and introspection over brute strength. These manuals enrich the knowledge of all players and Masters about the habitat, lifestyles, and preferred war tactics of certain monster races.
