RE: the original questions...
** spoiler omitted **
In our campaign, I am playing Ameiko's brother who has been fascinated with samurai and Minkai for many years, infact he is a Samurai. After a lot of unpleasantness in the campaign, alot of it caused by Ameiko, she has settled down and has named 2 primary advisors. I am one of them. One of my areas is to help train her in the culture of Minkai and prepare her to rule the Land of the Samurai. Fortunately, I have Suishen to help as everything my character knows, or thinks he knows has come from a small collection of books. I have been trying ever since we left Sandpoint to inform the others of the great difference in culture between Avistan and Tian Xa. There is little actual information on Tian Xa, a primer and a gazateer. Mostly the DM has allowed me to make up the culture as we go. As stated in the gazateer, I have based alot of it on feudal Japan.
