From the back cover: ENTER THE LANDS OF EVIL South of Rokugan lies the foul Shadowlands, the home of horrid demons and unnatural creatures. Centuries ago, the Crab Clan built the huge Kaiu Wall to contain these threats, but each day sees new assaults. Without samurai of courage and honor to defend against the threats of the Shadowlands, the Emerald Empire would surely fall. Shadowlands explores these dark realms and the tainted creatures that fest within, as well as the samurai who do battle against them at the Wall or beyond.
