In the mystical realm of Rokugan, the fortunes of the samurai clans rise and fall with the tides of the River of Gold. Wherever it flows, gold coins seem to follow, enriching the ports, manors, markets, and shrines along its banks. For centuries, this waterway has incited rivalry between the clans, for whoever controls the river controls the destiny of Rokugan.

Now, a new threat has appeared on the horizon, as a brazen river pirate fleet dares to plunder the merchants protected by the clans. It falls to the lords of the Crab, Crane, Scorpion, and Mantis Clans to end the river pirates’ raids before they threaten the prosperity of the Emerald Empire. Which clan will be the one to put a stop to the so-called “pirate prince” and reap the rewards of his capture?
