War Against Fu Leng

When the Kami fell from heaven, Fu Leng punctured a hole through the earth and into Jigoku. Exposure to the realm of evil drove the ninth kami insane and powerful. After returning to Ningen-do, Fu Leng began to destroy his siblings' empire in a fit of jealousy. Since that time, there has been conflict between the Empire and Fu Leng's realm, the Shadowlands.
