Here's the place to discuss the development of Tian.
Tian was originally refered to as the "Orient" and given as a throw away joke about how "the East" is actually closer to one's west (at least for those living in North America). Since then, it has evolved into a pastiche of Wuxia based around the fall of the 100 schools under Legalism. Philosophers are freedom fighters with a strong sense of honour and the government is either inefficient, ineffectual or outright tyrannical. Those under the control of Legalists tend to be the latter.
It is pretty well developed comparatively to other settings because my childhood contained just a little more Kung fu than Bollywood, but is still rough around the edges.
Okay; Tian's history is heavily inspired by the Era of a hundred schools, with mirroring China at the time was in constant civil war until the union under the Legalists; followed, both in Deixis and on earth with "The Burning of the Books and the Burying of the Scholars". Unlike in Real life, we're having those schools still cling to life as rebels and exiles, playing a Wuxia role; either guarding the old traditions or trying to modernize or just force common decency on to the Legalists.
In real life; the switch was quickly made over to Confucianism once the Empire was united, because, well Legalism was pretty damn harsh and without a legitimate threat was pretty hard to justify. This conversion was made peacefully but a lot of people argue that it was more posturing and in spite of the apparent conversion, the government was as harsh and legalistic as ever only now with the veneer of ideals of family, adding nepotism into the mix.
In Deixis; The Confucians, aided by the other rebels managed to over throw the Legalist emperor, but what to do after proved more difficult than they expected. Mohists and other schools wanted to split off into their own nation, so before you knew it, the Confucians accepted the aid of Legalists in keeping the country united, crushing the last organized philosophical rebellion.
Now; Confucians are in charge, for the most part they are to be judged on an individual level; Some [the PCs and more reasonable authority figures] are honourable men who uphold tradition and believe the state owes the people the duty that a father owes his son and are willing to fulfill it, others are irresponsible and corrupt men who made it in through nepotism and are letting the country rot through their irresponsibility.
Legalists are a bit more single minded, but not without their own pros and cons; They are ruthless, utilitarian and hold everything up to the letter of the law; they are willing to fight against corrupt officials who break the law, not to mention that they were, and probably still are, the only thing stopping the entire nation from breaking into violent civil war. But will just as quickly turn on nobles thieves, heroic rebels and generally play adversary to anyone willing to break the law regardless of good intentions [Which considering the feeling of Wuxia I have been working on for this campaign, will mark them as the main adversaries]. Keep in mind that they [for the most part, at least] are not stupid in enforcing the law and will either temporarily ignore minor threats in face of bigger ones and are willing to negotiate terms with bigger threats.
Daoists; More Religious, with a feeling of apathy towards the laws. Generally they've retreated into the forests and are too big a pain to attack and too little a threat for Tian to really concern itself with. Along with Buddhist Monks, Daoists tend to fulfill the wandering monk archetype. There are groups of them here and there scattered through out the Empire who are willing and ready to rebel [These tend to be more religious than philosophical Daoists and would be represented by large numbers of low level philosophers and level 0 Peasants], while others generally just avoid attention and keep to themselves.
Buddhists; More or less the same as Daoists, though slightly less common, less apathetic about laws [that is they don't necessary care about enforcing them but are willing to follow out of politeness while Daoists are prone to simply ignoring laws they do not like] with temples hidden among the moutains in place of villages or forest hide aways.
Mohists; Rebellious villages here and there follow the Mohist example, extremely utilitarian and simple, but most of the rulers should serve as Wise Authority figures but not above trickery to survive. Willing to exile dissenters, possibly worse if they cannot risk people leaving to the Confucians. Individual Mohists are champions of the people, protecting the weak and powerless against corrupt officials.
Other Eastern Philosophy; There are several other Philosophies to choose from, as a general rule, we're avoiding Japanese ones for now and considering adding them in as an island nation later. Most of these would be individuals hiding among large towns or wandering Tian, adventuring and the like. For the most part these philosophies are dying but survive through tutelage, and the priority of most would be keeping their philosophy alive by taking on students, preserving what they can in texts and in time of unrest, converting the populace to their cause.
Non-Western Philosophy; To keep the Wuxia feel, Tian is quite isolated. Forgienners have difficulty getting in, and even more difficult getting around the few port cities that they are allowed to enter. Those who leave port cities are constantly hiding and on the run, drawing attention to yourself will get Legalists after you, and depending on your actions Confucians as well [though it is possible to earn the respect and support of individual lords].
All of this of course, is just the background to player characters doing Verbal Backflips and Rhetorical Reversals; The heroes play the part of honourable rogues or even law abiding officials on the trail of corrupt officials plotting against the Emperor or just being jerks to the peasants, fighting criminals and other villains along the way. Essentially the essence of Wuxia or Kung fu Robin-hood for the simplest western equivalent.
