Bhuddhist principles, with a western outlook. Its a bit of a evolutionary (enligtenment) vs devolutionary (base physical desires) conflict. The society is evolutionary while there is a rebel devolutionary faction which forces itself upon the political landcape. While im using 3rd ed terms to descibe the classes, this is a 2nd ed world.
Character Classes, from Highest societal status to lowest.
1) Monk, a converted version of the Oriental Adventures one. Highest social class in normal society, being the enlightened leaders and ideal of the civilization.
2) Shaman, a divine spell caster whom is a mixture of druid and exorcist. Chiefly deals with non-physical matters aswell as nature/spirits on a whole. Respected for thier wisdom and elightenment.
3) Initiated, A form of arcane magic use use which can only use certain spell types such as divination, some alteration, abjuration and that kind of "Evolutionary" magic which mostly ignores the physical aspect of magic. These are the "Good" mages, atleast trying to become more intune with the universe. Known as white magicians, they are given a modicum of respect.
4) Liberator, the somewhat respected and oftimes controvertial thief. They are viewed in the same light as braces by the populus; upleasent but good for you in the long run. They are distained for thier lust for material goods and the physical world, while they are lauded for breaking the devolutionary links of weatlth and unnessessary goods with impede enlightenment.
5) Fleshtender, the priests of the healer goddess. They are scorned for thier methods of preserving base flesh at the expense of true enlightenment, although they are seen as a neccessary evil by the somewhat spartan society on a whole. Still, there are no others who can compare in thier healing lore like the Fleshtenders whom call themselves by different names for certain.
6) Illusionist, one who dabbles and manipulates the illusion of reality, sticking thier metaphysical hands into the devolutionary mire of creation. These arcane spell casters use Evocation, Conjuration, Illusion, some necromancy and other aspects of ther physical world. They can learn and use the spells that the Initiated cannot, and are often refered to as black magicians. While they are not inherently evil, they are viewed as being such by many.
7) Man-at-arms, a classical fighter. These are the pariah of the society, merciless killers whom rely on devolutionary weapons and armor to ply thier trade. They horde posessions and use them to end life with brutal effeciency. If they were not needed for the perenial invasions from beyond, the reprehensable eta class would be eliminated.
Its just an idea of a setting, but sometime i ought to establish it and run a game.
