From the back of the book: There are times a Games Operation Director wishes they had a Bulletproof Screen to keep players away from their secret notes and protect themselves from outraged gamers. Your wish has come true. This screen prevents gamers from nosing through your secrets, and it puts all the most used charts and tables in one handy place for the Haven: City of Violence RPG. In addition to this screen, there are maps of Haven and full-length adventure included with it to start the action off right.
