The Great Yin Dynasty has stood for three hundred years, with its capital at “Shenjing.” Peace reigns on the surface, but the realm is beset by troubles at home and abroad. The imperial court and the vassal princes vie for power, while factional struggles rage within the court. The “Northern Barbarian Khanate” eyes the northern frontier hungrily, and border incursions are constant. Martial sects fill the land, locked in conflicts between righteous and wicked forces, while reclusive sects secretly collude with the powers at court.
