well then, i advise you to remember that demons, ghosts, and spirits are all great bad guys, and the government should have administrators, teachers, clerics and mages on top, followed by a strong warrior system in charge, etc. very very stratified society.
Your party should be treated by the common folk based on their class, so bards and clerics and casters would be higher ranked and looked on with respect, while theives would be spit on and denied entrance to temples or what have you.
oh, and if you're playing along the banks of the Ganges, then make sure to have loads of marble temples, with ash coated yogis sitting outside in saffron colored robes, tending holy fires, and cremating bodies. And the river itself should have lots of pilgrims bathing, and little lotus flowers with candles floating down.
and stuff.
