The Poison Country is a Glorified Resort for ninja of the Village Hidden in the Clouds. As such it has an easy friendship with the Lightening Country. The locals have long feared the Spirits believed to inhabit the Swamp, which they named the Swamp of Death long before it was discovered by ninja. In the past, they have fought with the Ki country so long and bitterly that the river that serves as a border between them was called the Red River, but neither country was willing to cross the mountains or the swamp, so battles were always on the Eastern Plains. Now even these old enemies have known generations of peace.
