From the back cover: The Essential GM’s Reference to Legend of the Five Rings Roleplaying Slow Tide Harbor is a rough place, filled with crime and gaijin smuggling. What few know is that a blasphemous mahō cult is kidnapping local samurai and plots to use them as blood magic sacrifices—unless a group of outside investigators can uncover the cult’s hidden allies and unravel its schemes in time… Take your Legend of the Five Rings players into a network of sordid conspiracies with the Legend of the Five Rings Game Master’s Kit! In addition to a new adventure, there are new rules for creating player characters from the Tortoise Clan, the mysterious minor clan that rules Slow Tide Harbor, and a deluxe game master’s screen that places the most commonly-referenced rules close at hand. This product includes a 32 page book and a 4-panel game master’s screen. A copy of the Legend of the Five Rings Core Rulebook is required to use this supplement.
