The Great Clans of Rokugan have been teetering 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.

This premium expansion, like Children of the Empire before it, that contains a total of 234 new cards. While Children of the Empire focused on an Imperial theme, Clan War instead introduces two ways to bring multiplayer to Legend of the Five Rings LCG.

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 other's' 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.
