I thought of a character I could play. She'd have a Japanese name, look Japanese, and have a Japanese accent (L=R, R=L). If I was allowed to play a human like that, would the name Kiyomi Sakamoto be allowed, and would it be allowed to say she is from an "eastern country" ? I think it would make for interesting, if not weird roleplay.
According to Damien there are no explored lands beyond the eastern borders of his worldmap. The people who are closest to being asian and have a certain asian appearance are the Serinjah, which I guess could be compared with Mongolians.
