Since the launch of Legend of the Five Rings: The Card Game, the Great Clans of Rokugan have teetered on a precarious ledge. Now, in one night, that ledge has given way. New alliances have been formed, old rivalries have been ignited, and the Great Clans of Rokugan are prepared for all-out war.

Declare your allegiance with Clan War, a premium expansion for Legend of the Five Rings: The Card Game that contains a total of 234 cards and introduces two new multiplayer formats to the game. The Enlightenment format sees three players racing to claim all five elemental rings, while Team Conquest allows players to join up into two teams to break each others' strongholds. When the clans clash in open war, none can be victorious alone! Not only does the expansion include the rules for how to play these formats, but most cards in the set synergize with multiplayer play, and a treaty pad and cards included in the expansion allow you to form and break alliances.
