Yeah, I've always been a big fan of Japanese mythology. And, speaking of Japan...
China and Japan in Gods & Men
China lies in the far East of Asia, and once consisted of five separate provinces. But, thanks to his military prowess, Qin Shi Huang has gathered them into one unified China, and proclaimed himself the First Emperor of the Qin Dynasty.
Qin Shi Huang rules his China with an iron fist, burning books that would undermine his authority as well as silencing those who speak out against him. Despite his vindictive approach to dissent, the First Emperor has approved of the sciences, making China another haven for the great minds of the East (especially in the field of astronomy).
China is also home to the various sects of Wushu, an ancient form of martial art as old as China itself. The most famous practitioners of Wushu are the mysterious and reclusive Shaolin Monks, who are said to be so attune with their abilities to the point of gaining almost supernatural powers.
The Silk Road, the longest trade route in the world that was founded by the famous Roman explorer Marco Polo, begins in the Chinese capital of Xianyang, running through Persia and Greece, and finally coming to an end in the great city of Rome.
Across the sea from China lies the Land of the Rising Sun, Japan. Comprised of a handful of kingdoms ruled over by powerful Shoguns, Japan is a place of amazing beauty and xenophobia for any outsiders on it's shores, though the major ports, such as Osaka and Tokyo, do host trade ships from as far as the Rome.
Ruled by the warrior caste of the samurai, each Shogun is a powerful and charismatic warlord lording over a small army of equally skilled soldiers, who are ready to die for him on nothing more than a command.
The most powerful of these Shogun is a particularly proud man named Tokugawa Leyasu. Possessing dreams of grandeur, Tokugawa is assembling a large army of followers, both human and not, with thoughts of a Japan-wide Tokugawa Shogunate.
Also a powerful part of Japanese society are the many different ninja clans that operate among the populace. Not possessing any of the ideas of honor that the samurai maintain, the ninja are some of the most skilled, and feared, assassins on Earth. Operating in stealth, ninjas perform their tasks with frightening ease, be it theft, kidnapping, or even murder.
