As is often the case in tabletop roleplaying games, players will often venture into locales or look for answers in places and among people busy Game Masters simply can't anticipate. Or, just as often, an adventure won't have fully fleshed out characters in place for the locations that are detailed for gameplay.

The Game Master's Book of Non-Player Characters solves those issues and more by providing Game Masters with the information they need to “fill in the holes” in their campaign play. It will enable referees to instantly add depth, color, motivation and unique physical characteristics at a moment's notice to unexpected or underwritten characters which appear in their gameplay, ensuring that every encounter is a memorable one for players and GMs alike.
