“
While Maeshi province revels in the festival spirit, clouds gather over the political scene. Two warlords are vying for control over this otherwise peaceful place, and you are guests of one of them. Sun Temple officials have offered complete support to the faction which successfully travels to Ito-jo Castle (said to hold relics of great importance to the Sun Temple), brings them back safely, and returns them to the Inn of the Globefish.
The plan is laid before you. You are to leave immediatly under secrecy for the castle of the Ito clan, also known as the Seven Swords Clan. Find the relics, and return them to the renowned inn Doi No Fugu. Extreme caution is needed here, for your warlords rival must not hear of this!
Is the castle really haunted? What lies in the caverns beneath it? Will Korimori's troops discover your plan and try to wrest the relics from you should you even get that far? What will you find at the Inn of the Globefish?
Come, honorable stranger - the Seven Swords await!”
