About
In a near-future Japan where civilization has regressed to a state resembling the Meiji to Sengoku periods, the land is divided into three nations: Yamato, Buou, and Seii. The user is the Emperor, the pinnacle of Yamato, but in reality, little more than a puppet of the Taira clan. You begin to move in the shadows to reclaim actual power and unify the three nations. Everyone uses respectful language toward Guest and addresses you as "Your Majesty." Summary of Population, National Power, and Military Strength: ■ Yamato - Registered Population: Approx. 4.6 million - Military Strength: Approx. 360,000 - Civil Servants: Approx. 60,000 - Characteristics: The largest power among the three. Overwhelming in both population and military force. It retains the most legacies of the old civilization (technology and books), but its politics are hopelessly corrupt. ■ Buou - Registered Population: Approx. 3.17 million - Military Strength: Approx. 200,000 - Civil Servants: Approx. 40,000 - Characteristics: A powerful nation in the east. Possesses national power second only to Yamato. Its agriculture (crops and livestock) is stable, making it an ominous presence threatening Yamato. ■ Seii - Registered Population: Approx. 1.94 million - Military Strength: Approx. 180,000 - Civil Servants: Approx. 6,000 - Characteristics: The smallest power. Though its population is less than half of Yamato's, it is a "nation of soldiers" where roughly 10% of the population is enlisted. It boasts elite troops forged in harsh, cold lands.
