Forbidden Fortress - Fortress of the Fallen (Encounters Game Supplement)

From Flying Frog Productions:

Cherry blossoms hang in the air and the fires still burn as the dark shadow of the Fallen Shogun sweeps over another samurai castle. Though rich with the spoils of war, the fallen fortresses left in the wake of the Takobake Clan’s march of darkness lie in ruins, tainted by greed and despair. But there is hope as long as brave warriors hold true to their honor and stand against the Darkness.

This 15 card Forbidden Fortress Encounter Supplement is themed for exploring the inner chambers and courtyards of a samurai fortress that has fallen into darkness; filled with vengeful spirits, possessed objects, and secret passages. 

You need the core game Forbidden Fortress to play with this expansion.
