From the back of the book:
Years ago, the world began to end, and the rules for reality were torn asunder.
Today, the end is still nigh, but the rules are clearer than ever.
The Torg First Edition Revised and Expanded Rulebook combines a decade's worth of rules updates, additions, and player comments into one comprehensive volume. At nearly double the size of the first edition rulebook, this is the biggest and most comprehensive resource for the Torg roleplaying game ever produced.
Whether a neophyte in the Possibility Wars or a long-time defender of reality, the Revised and Expanded Rulebook serves as the most important repository of the rules, skills, spells, miracles, special abilities, and equipment necessary to keep up the fight.
Your devotion to preserving the real is your greatest asset.
This book is your greatest tool.
You'll need both.
