From the #1 Best-Selling author, Jeff Ashworth, comes the latest addition to The Game Master series, with more than 500 NPCs ready to populate your campaign whenever you need them! As is often the case in tabletop roleplaying games, players often venture into locales or look for answers in places and among people busy Game Masters simply didn't anticipate. Or, just as often, an adventure won't have fully fleshed out characters in place for the locations and encounters outlined for gameplay. The Game Master's Book of Non-Player Characters solves these issues and more by providing Game Masters with the information they need to "fill in the holes" in their campaign play. It will enable GMs to instantly add depth, color, motivation and unique physical characteristics at a moment's notice to unexpected or underwritten characters as they pop up during gameplay, ensuring every session is a memorable one for players and GMs alike.This edition also includes more than 50 hand-drawn illustrations of select NPCs detailed in the book, 3 bonus one-shot adventures, and a foreword by online influencer Jasmine Bhullar.
