The Grand Mook Manual Vol. I is a valuable resource for any GamesMaster. The book is all about Non-Player Characters with advice on roles and building encounters as well as the NPCs themselves. It contains over 90 mook tables (NPCs defined by numbers & stats), over 30 average mooks (NPCs defined by their jobs), and over 70 ready-made and fully-fleshed-out honest-to-goodness NPCs. This book is invaluable when in a pinch for GMs when needing some quick mooks right now.
