From the back of the book:
For over a decade, Role-Players have come to the Emerald Empire of Rokugan to learn the true meaning of honor and glory. Now it is your turn to take up your katana in the name of your clan.
The Minor Daimyo Doji Haruki has always craved more power and prestige among those who possess true influence in the Imperial Court. Now, on the eve of his greatest and most promising court, mere hours before his moment truly arrives, his most valued treasure is stolen. The daisho of Seppun Daiori, gifted to Haruki by the Seppun family, is mysteriously absent. Fearful that his greatest triumph shall become the the moment of his ruination, Haruki turns to a handful of samurai who arrived for court ahead of schedule, desperate for their aid in returning the daisho before the court concludes.
