A little break from Crimhuck - A Oriental Campaign Idea

I've been kicking around the idea of running a oriental campaign.  It's amazing what flipping thru a few different DMG's and your imagination will do.

So here's the premise I have so far.

A large city that holds the emperor and his seat of power has been overthrown by the invading Rakasta.  New's has come that the emperor has been slain.  The previous guard/army has either been killed, captured, escaped or pressed into service of the new warlord.  (Samurai's)

Not far from the huge city is a small village on the outskirts of the empire.  This is where we find the hero's.  Some of them are leftover's of the previous regime (samurai's), some are monks from a nearby temple, some are ninja's, and some are wu-jen (sorcerers).

The village is in trouble of being overrun by the invading Rakasta.

The local factions - the monks, town guard, and possibly the ninja's (not sure on this).  Are desperately trying to stop the advance, but they are dissuaded at every turn.  Some members have switched allegiance.  Other's have been bought.

A new army must be raised, to combat the Rakasta problem.  But that's not the only problem.  Some seer's say that they've seen dragons in the sky.  Other's believe a new emperor must be found first.  The PC's maybe sent to envoy with another nation to discuss trade talks and help with the Rakasta problem.

There are of course spies everywhere.  And because of the change in government there is chaos in the streets.

That is all i've got so far.
