For the second edition of the Legend of the Five Rings (L5R) rpg, they split the core rules into two books: a Player's Guide and a Game Master's Guide. Notably, the game is listed as a Wizards of the Coast endorsed product as this arrived during the period when the L5R CCG intellectual property was under WoTC's control. It advances the metaplot to post-Clan War and closer to the first CCG material. It integrates a great deal of material from various supplements for the first edition of the L5R rpg. Also worth noting that the ready-to-play adventure presented here is a sequel to the adventure included in the first edition of the L5R GM's screen.
