From the back of the supplement: "Throughout mankind's history, warfare has been an endemic part of his culture. From tribal beginnings to the rise of the Roman Imperium and beyond, man has waged war. The tools of this brutal trade have changed over the years, from simple stone to complex metal. They have changed as necessity dictates and experience allows. These are the arms and armor of the early medieval period of Western Europe. This book divides the various weapons and armor types into a brief listing that gives the vital statistics of the item in question, followed by an annotated description and history to allow Castle Keepers to place an armament in its proper historical context."
