From the Foreword:
This book could save your life.
I can't claim to have fought and killed every creature in these pages.
In fact, I can't even claim to have run away from them all.
This book will help you do both. Maybe even at the same time!
Not all the creatures in this book are mindless monsters. Many are intelligent, some even more so than most humans. They have their own societies, religions, language and traditions.
Of course, that doesn't mean they don't want to rip your guts out and eat them.
