The Scorpion Clan daimyo, Bayushi Shoju, has come to believe that an ancient prophecy long held by his clan (the Prophesies of Uikku) indicate that the 38th Hantei Emperor will be the source of a consuming evil that will destroy Rokugan. He acts on these beliefs by killing his liege, the 38th Hantei, and then attempting to hold the Imperial capitol of Otosan Uchi against the massed armies of the other Clans. This defense will be successful if the Crab Clan throw their allegiance behind Shoju. [ The next events occur after the end of the Coup, but before the Imperial Edition begins ]
