From the back of the book:
Enter a world of shadows, where nothing is as it seems and death lurks around every corner. Welcome to the city of Tokyo, seat of power for 3327 and the realm of Nippon Tech, where ninja haunt the darkness and the fate of a reality is sealed beneath the harsh lights of the Ginza. The Storm Knights of the Rauru Block present a guide to the city, its districts, strengths and weaknesses, and those who wield power within.
This supplement for Torg: Roleplaying the Possibility Wars features detailed information on Tokyo, including maps, new locations, new gamemaster characters, new templates, and two new mini-adventures set in the heart of Japan. It is designed for use by both players and gamemasters.
